Hi Sam - your friendly cohort in science here with another peer review! To help your followers: 1) there is no "J" in the institute name! I got lost Google-searching for JIAP! "Researchers at the Department of Instrumentation and Applied Physics (IAP), Indian Institute of Science (IISc), have designed a novel ultramicro supercapacitor" so I hope next article you do on this will have it as "IAP". 2) At timeline "1:52 shelf life capacitors on the other hand 1:55 can store electric charge for much 1:57 longer by virtue of their design" I know what you meant. but it is not what the words say. Since I have both BS & MS, EE, I can help with this. Capacitors CANNOT store electric charge for very long at all - they CAN retain their ability to store charge for longer in their operating lives. This is a HUGE difference in communicating what the can and cannot do, with just a few subtle word changes. The general public will be confused into believing that they hold a charge for a long time with the current wording. Otherwise - great article, as usual. Cheers! Your Friend, Tom G. Also, why not include a hyperlink to one of the text articles, like this one: scitechdaily.com/ultramicro-supercapacitor-a-game-changing-energy-storage-marvel/
I could see super capacitors added to EV's. Regenerative braking charges too fast for batteries and going from stopped to moving takes lots of energy. Capacitors could supplement batteries and be especially useful in stop and go traffic. May also be good for wireless charging. You might be able to make an EV with a smaller battery which would save weight and cost less. This could be the future for Urban Robo Taxi's.
There should be very functional applications for this, my thoughts are for the space industry and aviation. However, since these are small, the defense industry,, their need for lightweight drones etc. Very interesting, please follow up with another episode when you have new information.
If you want to move 50kWh in 2min, you need to push 1.5MW. Even 125A cables on 50kW chargers can be a little unwieldy when it is cold and cable length is tight, imagine having a longer 1500A cable into a 1kV battery pack! People will be wishing for power-arms to help them move that around and plug it in. There are practical limits to consumer fast-charging and 500kW will probably be it at least until we get chargers with robotized plug-in.
Maybe if we ask Tony Stark he can work something out...I mean...we could split the energy between the 9 realms. We'll just have to put a charger at Yggdrasil to harvest all that sweet discriminating energy.
@@davidrandall2742 Wireless charging has high losses. At absurdly high power levels like 1.5MW, we'd still be talking 75kW worth of losses even at 95% efficiency. Pissing away 75kW just because you don't want to use a plug doesn't sound very eco-friendly. For that amount of power and current, you'd likely want to have the charging contacts directly on the battery pack itself to eliminate intermediate wiring losses. Park over the charging pad, the pad aligns with battery contacts, cleans the pads, applies 1kN of lift to make contact and ramps up current while monitoring the voltage difference between battery pads and charging pads for contact quality.
I appreciate that Sam said it's not a sure thing. This story came and went already, I hope it comes back, it could affect Cooling and Battery chemistry used as a buffer, Nissan should have figured this out.
Super capacitors are used in trams so they can get started without arcing the catenary. They are routinely replaced. Many former tram supercaps still have a lot of useful service life and can be bought qiite cheaply, for a fractipn of new price.
Supercapacitors are perfect for pulse weapons. (Stay tuned to Kentucky Ballistics.) There are direct current motors and alternating current motors, but no capacitor driven motors.
Supercapacitors are very useful in energy-recovery systems such as you find in hybrids and electric vehicles due to their very low internal resistance. For example, a typical EV battery can soak up around 150kW of power during regeneration and it could hold that rate for many minutes. A super-capacitor, on the other-hand, would be able to soak up megawatts of power, but would only be able to hold that rate for a few seconds. So supercapacitors won't be replacing batteries, probably ever. They don't have the energy density. But for short-term energy recovery and generation purposes the super-capacitor can operate at 99%+ efficiency while an EV battery would be sitting at 85% or lower (at those wattages) due to the voltage drop caused by its internal resistance. Similarly, for handling short-term acceleration (such as accelerating from a stop), a super-capacitor could be charged slowly from the EV battery and then discharged quickly into the motor at much greater efficiency. That is the main claim to fame and this "discovery" (if it could be called that... I'm skeptical myself)... it probably isn't going to change the equation much. That "3000%" quoted was clearly under extremely fragile conditions and probably relative to very low amounts of capacitance in the first place, for example. A game changer? Maybe decades from now a portion of this research will be in use as part of super-capacitor system. It sounds rather expensive.
Strangely enough, the main "issue" of super/ultra capacitors since the beginning is their very limited capacity ! How fun this is... The reason is the way how the energy is stored : electrons versus ions in batteries. I don't believe that super capacitors will ever surpass batteries, because energy density via electrons will never be able to compete with the one of batteries.
The application for this tech is supercars, EVTOLs and electric airplanes, because they will be able to pay the high price for it. I suspect that for most of us, we will only use LFP, LMFP or sodium ion, because price per kWh will be the most important factor.
Living for 70 years in the 5 volt electronic world, and 110/220 volt US residential world. Should there be concern regarding high voltage capacitors, mega chargers, EVs with 800volt architecture in the hands of everyday housewifes? I remember a few wet/110 volt deadly groundings as a kid.
Microscopic supercapacitors built on chips in a wafer fab may be OK to integrate small amounts of capacitance into an IC, but the cost per joule stored will rule out their use for bulk energy storage. Even with a micrometer of thickness built on the chip, which is huge, a square meter of silicon would only have 0.01 cubic centimeters of supercapacitor.
Supercapacitors are general orders of magnitude removed from having the energy to mass and energy to volume ratios of batteries. So this may well be a better supercapacitor, but I think it's stretching things to suggest it's going to replace batteries.
They're becoming quite common in electric forklifts. While they don't store as much energy, they will charge in the time it takes you to go for a pee. In a 24/7 warehouse operation, it results in higher uptime, compared with a unit that has to sit for several hours recharging batteries over that same period.
All that matters is the energy density and cost per kWh, and we are a long way off capacitors getting anywhere near batteries in terms of energy density by at least an order of magnitude. Batteries already provide sufficient power. Like all your other science announcements, it it was any good they would be already being sold and used in products. Its possible to produce high capacitance, but not high voltage, so the higher you go with capacitance the lower the voltage tolerance. They don't mention this so we can assume that is what the problem is.
The thing about capacitors in the old days is that even though they could take 250,000 cycles they would only hold a small amount of energy. Then they were opt to release it all at once. However, in the early 2000s Brigham Young University (BYU) out of Salt Lake City, Utah took an EV1 and replaced its batteries with supercapacitors. I saw them bring their capacitor powered car to The Power of DC, an EV drag race event held just outside of Washington, DC, where a bunch of homemade EVers used to drag race their EVs against each other. The caps powered EV1 from BYU would push so much power through the motor that it would twist break the axles on their EV1. Drag racing seemed the perfect place for supercapacitors because they would release all their energy in a few seconds and then they were empty. To solve this problem in electronics engineers time a bank of capacitors to release a row at a time, timed with the Hz of the electronics. Its like going small pop, pop, pop etc. to create a better smoother flow of current. Because they can be cycles for forever, (250,000 cycles) and they can capture energy so fast they really are perfect for charging with regenerative braking and then releasing that captured energy to overcome inertia, an object at rest will stay at rest unless acted upon. EVs use a lot of energy to just get going. Once they are going they don't need as much energy to stay going, An object in motion will stay in motion unless acted upon. This would leave the batteries with only the duty of keeping the vehicle going through wind resistance, mechanical resistance and road friction resistance. The problem with capacitors in the old days is that they would take up a lot of space for the volume of energy they stored. This breakthrough seems to solve the energy volume problem. With that using capacitors for all phases of EV energy storage and use would be possible. Capacitors don't really go bad like batteries. It is not a chemical reaction that has to take place in order for them to charge and discharge, so there is nothing to wearout. Original capacitors use an electric field to hold the electricity. Any of you know what a Leyden Jar is? It looks like these dudes are going old school. I mean really old school, like the middle of the 1700s old school.
I'd put this one in the 'wait and see' basket. I looked at Sam's source for the story after doing a search myself and found a different 'source' with virtually identical wording. This looks like just a regurgitation of a common press release. While I sincerely hope there is a genuine breakthrough here, I am hesitant to start popping champagne corks just yet. Here is why I'm dubious. First, apologies for the length, but once you understand the difference between batteries and capacitors, the reason for my caution will hopefully become clear. The TL;DR version is that capacitors have a long way to go before even coming close to the energy density of a battery. The likelihood that some scientists have closed that gap in a single bound is remote. Here's the non-TL;DR version... Capacitors and batteries store energy very differently. Batteries (or cells to be precise - a battery is a bank of cells and a cell is the fundamental unit storing energy this way) store energy chemically. Current is generated via ion exchange between two chemicals separated by an electrolyte. The voltage produced is a byproduct of the particular chemicals used. In some cases, the conversion from chemical energy to electrical energy is reversable. We call these "rechargeable batteries". Capacitors store energy as a static charge. You have two plates separated by a dielectric material - basically an insulator. When you charge a capacitor by applying a voltage across its two pins, electrons rush onto one plate causing electrons on the other plate to be repelled. This is why a capacitor appears like a short circuit when it is charged as current seems to flow through it. If you remove the voltage source, one plate is left with an excess of electrons with nowhere to go. The other plate has a lack of electrons with nowhere to get them. Since the dielectric substance is never a perfect insulator, electrons will cross slowly over time, so they will self-discharge, but let's ignore that for now. So, if you take this charged capacitor and apply it to a load, suddenly the electrons have somewhere to go - through the load to the plate lacking them. This continues until balance is restored and the capacitor is discharged. Unlike a battery, the voltage provided by a capacitor is determined by the voltage used to charge it. The voltage printed on the side is just its maximum rating - the point where the dielectric breaks down and the plates will arc across, most likely destroying the capacitor in the process. In fact, the higher the value of a capacitor, the larger it has to be to handle a higher voltage. Small value capacitors (useless for energy storage) can commonly handle hundreds of volts. Large value electrolytic capacitors (the big cylindrical ones in the video) can handle up to 35V, maybe a little more. There are bigger voltage ones but the point is the relationship between the value, voltage rating, and physical size. Unlike a battery, capacitors can be charged and discharged virtually without limit. Since charge is not stored chemically, it doesn't degrade through charging cycles. The dielectric substance can dry out and other things can happen to make a capacitor 'wear out', but for the most part, charging and discharging is not one of them. Unlike a battery, a capacitor can be charged and discharged at virtually any current, basically subject to the thickness of the wires connecting it. They don't need to have their charging cycles handled with kid gloves like a battery. Theoretically, they can handle as much current as you can dump into it or draw from it. So, why are we not using capacitors instead of batteries already? Storing energy as a static charge is nowhere near as energy dense as chemical storage. The formula for calculating the energy stored in a capacitor is E = (CV^2)/2 where E is the energy in Joules, C is the capacitance, and V is the voltage. In days of old, a large value capacitor would have been of the order of 33,000uF (micro-Farads). Charged up to 24V, this holds about 9.5J or 0.0026Wh of energy. By comparison, a Tesla 4680 cell is claimed to hold almost 100Wh (360,000J) of energy. Note: there are 3,600 Joules in a Watt-hour - it is like converting centimetres to inches. I recall many years ago when there was a breakthrough in capacitors. It was the birth of the supercapacitor which was nothing more than an ordinary electrolytic capacitor with an extraordinarily high capacitance value. It was a 1F capacitor capable of 5V. It's first application was to solve a big problem in the humble PC, replacing the 'coin battery' (usually a CR2032 or similar) maintaining the real time clock and CMOS RAM that stored the configuration. That 1F capacitor charged to 5V could store 12.5J of energy - wow! Remember that a capacitor stores energy based on the voltage charging it, so that old 33,000uF capacitor charged to 5V would only store 0.4J. So, a supercapacitor is just a large value ordinary capacitor. In order to improve the energy density, some manufacturers created hybrid supercapacitors merging the ordinary supercapacitor with the lithium ion battery. While they benefitted from a greater energy density, they also suffered from the drawbacks of the two technologies. For example, unlike an ordinary supercapacitor, the hybrid could not be allowed to fully discharge because of its lithium ion battery component. Going back to the subject of the video, a Field Effect Transistor (FET) is as its name implies, a type of transistor. From reading the articles it is unclear precisely how it is used and how it benefits the supercapacitor. I don't know if it is relevant, but one thing about FETs is that they have a parasitic capacitance (this refers to capacitance that is a byproduct and not necessarily wanted) between the gate and source/drain pins. In plain English, the voltage applied to the gate and source pins of a FET controls how much current is allowed to pass from the drain to the source pin. It's a bit like a tap where how much you turn the knob determines how much water flows. The thing is that the gate is insulated from the source/drain part in the same way that the plates in a capacitor are physically separated. The FET uses the excess or absence of electrons induced across the gap to choke off or open up the flow of electrons. They may be employing this aspect in their new design or it could be something entirely different. So, these scientists have a huge gulf in energy density to jump. The question is whether they have done it in one go or simply taken another incremental step towards closing the gap?
@@lxoxrxexnx , of course you are right. I was so accustomed to working with MJ and kWh, I just used my usual 3.6. I will go back and fix my comment. Thanks for pointing out my mistake.
Yes, I googled it as well. Not only that, but the graphics they use are mostly unrelated to the actual topic (and the ones Sam uses are too... I think he *accidentally* included a graphic of an actual super-capacitor in one or two places, but most his video references were of normal capacitors). So basically all the media is creating a word-salad of nonsense with very little real information inside it. There is only one actual graphic (the one showing the MoS2/SiO2 and FET). Brings back memories of the "nuclear battery" nonsense a while back.... people forgetting the ultra low currents those things generate. But back to the FET. I couldn't find a deep reference to what they were actually using the FET for, and none of the graphics shed much light either. It clearly is not being used for current control. The implication from the very poorly-worded media description is that messing with the gate is changing the capacitance between the electrodes (MoS2 on one side and SiO2 on the other). Which sounds interesting, but is kinda worthless on its own. This will also depend heavily... very heavily, on the voltages involved. Super-capacitors are pretty much universally less than 4V but gate controls tend to universally be more than 5V. How they are supposed to pack the layers together into something dense enough to be called a super-capacitor, I do not know.
Another name for a capacitor that stored more energy than a Lithium battery would be a bomb. Unlike batteries when a high capacity capacitor fails it releases all its energy instantly. A 75kw car capacitor going off would release about the same energy as a 155mm artillery shell.
So a few of these in my scooter would give it unparalleled acceleration at the traffic lights,then battery would kick in energizing the supercapaciter for the next stop/go.this is the same as aviation take off,or e car efficiency
There is a problem with high speed charging of battery packs and that is the amount of energy that the grid can supply. If you take the average house electrical supply in the Uk (80 amps at 240 volt or 19.2 Kw) a 50 Kwhr battery pack will take around 2.5 hrs to charge from low and this does not allow for any use in the house. You could use public high speed chargers but they are expensive per Kwhr as the company running them want to make a profit. If you are able to charge your car in 3 minutes (say 50Kwhr battery - it does not matter if it is Li ion or supercapacitor) you need a supply capable of 1000Kw (1 Mgw) or the average daily use of 125 houses. The idea is good but ulta high speed charging will present major problems for the grid. If you have a charging station of say 20 chargers they will require the energy capacity for a small town. One way to allow high speed charging might be to limit the time of day it can be done.
The grid capacity issue can be overcome by having local battery storage with the charger. The big problem is the connection to the vehicle. Can you imagine the thickness of cable needed for a 2 min charge!
For a 3 min charge on a 400 volt system you are looking at around 2500 amp. To put that in context the current 350 Kw chargers charges at 875 amps. These charging cable can be a problem now so a cable twice to three times the size would be impossible to handle. @@petewright4640
I think ot is an interesting development. There is a growing body of literature that suggest that Li-ion battery technologies and supercapacitor technologies are increasing evolving to a common median in terms of capacity to performance ratio and function. I don't think we'll get as far as replacing EV batteries with ultracapacitors completely because the features and use case of both different. But there have been many stories in the past of complementing EV batteries with capacitors to more efficiently capture and release energy when accelerating and decelerating the EV, because the efficiency amd potential performance is better than what batteries can achieve, without thermal issues to.the battery. So combined as hybrid battery it could make EVs more efficient. Other ideas have been to replace the 12,24, 48 V EV battery with capacitors to improve longer performance over time. Weather and cold impacts capacitors less, which makes them more ideal for that purpose. I can also see ultracapcitors greatly improve inverter technologies for consumer grade products and pcb use and in EVs to make more compact products at less weight and cheaper price to build, which improves space and weight savings. And of they have better thermal properties they could potentially also greatly improve consumer grade electronics with less risk of fire risks for consumer based products.
Really need the stats on this capacitor, what is the watts per kilogram? What is the volumetric density? Ultimately if you made them to fit in the same battery space in an EV as a conventional lithium battery would it heavier and / or would it have the same or better range? Capacitors tend to need lots of space and low energy density which is why you don't see many of them powering anything by themselves. Also how long do they hold a charge?
I built a car battery from supercapacitors (schematics and build description on my youtube), as well as several flashlights/lanterns some years ago. Another advantage of supercapacitors missed in the video is though batteries support thousands of cycles, supercapacitors support millions of cycles, and are not affected by the heat/cold our weather can produce. If they can get energy density (super cap current weakness) up high enough for EVs, then the supercapacitor could in theory last the lifespan of several cars being moves from one car to the next!
Super capacitor have high self discharge behaviour, while battery not, its major difference, so when you have high energy density of super capacitor its useless if you have long delay gap between charging and discharging, for example charging now and use electricity next day or next week
@@teknosql4740 self discharge depends on the quaility of the supercapacitor. Some cheap Chinese brands (like Green-Cap) are pretty poor grade, and discharge 20%-30% in less than an hour. Then you got brands like Maxwell (I use in my flashlights). Some of their capacitors had +90% charge after 6 months. If they can get the energy density of supercapacitors near batteries you'd have the perfect power source.
The main benefit of Super capacitors is they can store a very large amount of charge, but normally discharges at a faster than usual rate, which is good if you are accelerating a car, but not so good to run as a battery
gamechanger gamechanger after gamechanger - seems there is another gamechanger after the last game changer that will be superseded by another game changer that is likely hot air
Charging not only limit by battery, grid and charging system are limiting it so even if the battery can charge in 2 min you will need 3000kw good luck with that
I could see super capacitors getting incorporated into future hybrid battery technology. Theoretically they would be better than NMC and LFP for regenerative braking, pound for pound, in a performance vehicle
I believe that this is was being considered for the Pininfarina electric super car but see no mention of it on the Wikipedia page for the automobile. Perhaps still a possibility or just not itemized there, but more likely had to be scrapped due to complexity or cost, viability etc.
That energy density sounds too high for be real. That's because capacitors are based in electrostatic charge, not chemical based in ion exchange. The electric field generate problems that limit a lot the total charge in the capacitor that makes extremely dubious that supercapacitor can reach so high energy densities. Speaking of "X%" is doesn't said too much, as it depends of the base value. If you are taking a regular capacitor as a base, 5000% is not even enough to reach lithium-ion or even sodium-ion energy density. Of course, the high current that a supercapacitor can reach make it a preferred technology over batteries on some scenarios. But for high energy demand, like aviation, high energy density is a requirement, an even current market lithium-ion densities are not enough. So supercapacitor have even less potential. There is a possible cheat here. Because they are speaking of ultrasmall capacitors, maybe... just maybe, they reach that values because they aren't close one to another, so the electric field is not a problem. So while they have reach "absurd" levels of high energy density, they have a scalability problem to make big batteries. Just putting a lot together won't work. Which makes me think if it's possible build positive charge (lack of electrons) capacitors to compensate, so a big scale supercapacitor where made of internal positive and negative very capacitors, making a macrocapacitor of zero net charge. Is it that possible? I don't know. Besides, if the density were so high, it has very little sense to focus in reach even higher densities were the problems to turn into real products are raw material costs (gold?... not a chance for massive production) and mass manufacturing. So I think that this ultracapacitors can have very high densities for capacitors standards, but I doubt they are in that values. If it's confirmed (which I doubt), they they are missing the right focus, that it must be reducing the costs which means cheaper materials and new ways of production to reduce the cost and accelerate the manufacture process.
#new_tech . Super #micro #capacitor with #fet 's . Can store energy 10 to 20 times more than lithium-iorn battery. Will this help make #ev #flight possible?
Wow another game changer video. How many games do you want to change. Reading an articulate like he’s an expert. Can’t believe anything until it’s released as a product/ working in real life. If it works and he claims then it there will easily get investment for mass production. Also how many solid state batteries have you actually seen in a product? Answer zero!
I believe certain technologies will advance and make obsolete some of the current ones, just as the moment in time cassette tapes replaced 8-track tapes and then cd's replaced cassettes and now we are here: streaming straight off of the internet and almost no one continues to buy cd's or lp's for that matter. They still exist, but the masses have adopted the new tech. That day will come. No one knows exactly when or where, but it will arrive. I personally believe sooner (1-3 years) rather than later (15 years)
Keep it up Sam, but super capacitors? Yawn... I'll get excited when they make it to mass market and they can store even just 10% of a lithium battery. That said lithium capacitors are quite interesting.
The magic black box that provides power to our vehicle motors in 10 years and gives us "range anxiety free" 1500 mile ranges even in large SUVs ... may not even be called a battery anymore. When vehicle ranges are so great that almost everybody can do their entire round trip vacation roadtrips without EVER charging up on the road ... today's supercharger network will go the way of the phone booth.
Some sort of supercharger network will be necessary anyway. For instance, right now, my electric supplier offers 22kwh total off-peak overnight. So much more than 1 night charge to fill up my EV.
Unproven technology still being developed is not game changing. It's game changing when it's proven and then investments in a factory are made, the technology is scaled up and shown to be practical and profitable. Until then, it's an interesting science story with wonderful potential.
For many *decades* we had electric vehicles that transported us around town without any batteries - and yes, I was just a kid when I rode in them. I'm old now, but we had a whole system that let us go anywhere for a low price. But like idiots we gave it up in order to have our own cars. Now we're trying to go back to electric vehicles and we're forgetting that we were already once there. ☹️🥺😥
Those electric vehicles of which you speak had a serious limitation: they ran a fixed route on a slow fixed time table. FSD taxis will pick one up on their own schedule, take them to whatever their destination, attend to someone else, and another one will pick them up. Rinse and repeat. There will be no need for tracks or other overhead charging infrastructure. I believe the cost will drop below 10¢ a mile.
The game changes when somebody designs and manufactures a high-capacity product and the infrastructure to charge it as fast as it can be charged. When is that likely to happen? "Game changer", is like "Breaking News", tired of hearing it.
Another day, another game-changing technology, Sam's on the roll again 😉
Yeah, he does mental masturbation on unproven technology or anything about Tesla or Chinese EVs.
Capacitors are fascinating… I think we will see them in cars as a complement to the battery, as they can accept huge charges rapidly and discharge rapidly. This has huge potential for stopping (rapid charge) accelerating (rapid discharge) and is currently being used for this in some light rail applications.

Hell yeah!
I thought so too, I don't know why we haven't seen them yet. If it works out it'd be great to be able to add them aftermarket!
Thought some cars already incorporated them.
I also thought I seen a video recently where they said researchers have made a capicator that can rival modern lithium batteries in the next five years. I think I was a graphyne based super capictor (not graphene). Most likely vapor ware with researches these days trying to get more funding.
Issue always is scalability.

Supercapacitors are perfect for pulse weapons. (Stay tuned to Kentucky Ballistics.) There are direct current motors and alternating current motors, but no capacitor driven motors.
Supercapacitors are very useful in energy-recovery systems such as you find in hybrids and electric vehicles due to their very low internal resistance. For example, a typical EV battery can soak up around 150kW of power during regeneration and it could hold that rate for many minutes. A super-capacitor, on the other-hand, would be able to soak up megawatts of power, but would only be able to hold that rate for a few seconds.
So supercapacitors won't be replacing batteries, probably ever. They don't have the energy density. But for short-term energy recovery and generation purposes the super-capacitor can operate at 99%+ efficiency while an EV battery would be sitting at 85% or lower (at those wattages) due to the voltage drop caused by its internal resistance.
Similarly, for handling short-term acceleration (such as accelerating from a stop), a super-capacitor could be charged slowly from the EV battery and then discharged quickly into the motor at much greater efficiency.
That is the main claim to fame and this "discovery" (if it could be called that... I'm skeptical myself)... it probably isn't going to change the equation much. That "3000%" quoted was clearly under extremely fragile conditions and probably relative to very low amounts of capacitance in the first place, for example. A game changer? Maybe decades from now a portion of this research will be in use as part of super-capacitor system. It sounds rather expensive.
Strangely enough, the main "issue" of super/ultra capacitors since the beginning is their very limited capacity ! How fun this is...
The reason is the way how the energy is stored : electrons versus ions in batteries. I don't believe that super capacitors will ever surpass batteries, because energy density via electrons will never be able to compete with the one of batteries.
The application for this tech is supercars, EVTOLs and electric airplanes, because they will be able to pay the high price for it. I suspect that for most of us, we will only use LFP, LMFP or sodium ion, because price per kWh will be the most important factor.
Great. Another battery game changing breakthrough...
That's the 4th one this week. Throw it on the pile.
Living for 70 years in the 5 volt electronic world, and 110/220 volt US residential world. Should there be concern regarding high voltage capacitors, mega chargers, EVs with 800volt architecture in the hands of everyday housewifes? I remember a few wet/110 volt deadly groundings as a kid.
Microscopic supercapacitors built on chips in a wafer fab may be OK to integrate small amounts of capacitance into an IC, but the cost per joule stored will rule out their use for bulk energy storage. Even with a micrometer of thickness built on the chip, which is huge, a square meter of silicon would only have 0.01 cubic centimeters of supercapacitor.
This mornings game-changer from Sam. Looking forward to this afternoons 😂
Supercapacitors are general orders of magnitude removed from having the energy to mass and energy to volume ratios of batteries. So this may well be a better supercapacitor, but I think it's stretching things to suggest it's going to replace batteries.
They're becoming quite common in electric forklifts. While they don't store as much energy, they will charge in the time it takes you to go for a pee. In a 24/7 warehouse operation, it results in higher uptime, compared with a unit that has to sit for several hours recharging batteries over that same period.
Top 3 video all week MR Sam how’s th better half prayin for yall
All that matters is the energy density and cost per kWh, and we are a long way off capacitors getting anywhere near batteries in terms of energy density by at least an order of magnitude. Batteries already provide sufficient power. Like all your other science announcements, it it was any good they would be already being sold and used in products.
Its possible to produce high capacitance, but not high voltage, so the higher you go with capacitance the lower the voltage tolerance. They don't mention this so we can assume that is what the problem is.
The thing about capacitors in the old days is that even though they could take 250,000 cycles they would only hold a small amount of energy. Then they were opt to release it all at once. However, in the early 2000s Brigham Young University (BYU) out of Salt Lake City, Utah took an EV1 and replaced its batteries with supercapacitors. I saw them bring their capacitor powered car to The Power of DC, an EV drag race event held just outside of Washington, DC, where a bunch of homemade EVers used to drag race their EVs against each other. The caps powered EV1 from BYU would push so much power through the motor that it would twist break the axles on their EV1. Drag racing seemed the perfect place for supercapacitors because they would release all their energy in a few seconds and then they were empty. To solve this problem in electronics engineers time a bank of capacitors to release a row at a time, timed with the Hz of the electronics. Its like going small pop, pop, pop etc. to create a better smoother flow of current. Because they can be cycles for forever, (250,000 cycles) and they can capture energy so fast they really are perfect for charging with regenerative braking and then releasing that captured energy to overcome inertia, an object at rest will stay at rest unless acted upon. EVs use a lot of energy to just get going. Once they are going they don't need as much energy to stay going, An object in motion will stay in motion unless acted upon. This would leave the batteries with only the duty of keeping the vehicle going through wind resistance, mechanical resistance and road friction resistance. The problem with capacitors in the old days is that they would take up a lot of space for the volume of energy they stored. This breakthrough seems to solve the energy volume problem. With that using capacitors for all phases of EV energy storage and use would be possible. Capacitors don't really go bad like batteries. It is not a chemical reaction that has to take place in order for them to charge and discharge, so there is nothing to wearout. Original capacitors use an electric field to hold the electricity. Any of you know what a Leyden Jar is? It looks like these dudes are going old school. I mean really old school, like the middle of the 1700s old school.
WOW
TOTAL MAGIC
Game Changer !
When Tesla bought out Maxwell I thought they had plans for a super capacitor but it seems they needed them for battery technology.
Looks like Elon will make it work
One day we will have something that really is a game changer. No one will notice because the term is so overused that it has become near useless.
The one thing I have learned with Sam is that the game changes every day, sometimes twice per day 😮
Cheers mate
I'd put this one in the 'wait and see' basket. I looked at Sam's source for the story after doing a search myself and found a different 'source' with virtually identical wording. This looks like just a regurgitation of a common press release.
While I sincerely hope there is a genuine breakthrough here, I am hesitant to start popping champagne corks just yet.
Here is why I'm dubious. First, apologies for the length, but once you understand the difference between batteries and capacitors, the reason for my caution will hopefully become clear.
The TL;DR version is that capacitors have a long way to go before even coming close to the energy density of a battery. The likelihood that some scientists have closed that gap in a single bound is remote.
Here's the non-TL;DR version...
Capacitors and batteries store energy very differently.
Batteries (or cells to be precise - a battery is a bank of cells and a cell is the fundamental unit storing energy this way) store energy chemically. Current is generated via ion exchange between two chemicals separated by an electrolyte. The voltage produced is a byproduct of the particular chemicals used. In some cases, the conversion from chemical energy to electrical energy is reversable. We call these "rechargeable batteries".
Capacitors store energy as a static charge. You have two plates separated by a dielectric material - basically an insulator. When you charge a capacitor by applying a voltage across its two pins, electrons rush onto one plate causing electrons on the other plate to be repelled. This is why a capacitor appears like a short circuit when it is charged as current seems to flow through it. If you remove the voltage source, one plate is left with an excess of electrons with nowhere to go. The other plate has a lack of electrons with nowhere to get them. Since the dielectric substance is never a perfect insulator, electrons will cross slowly over time, so they will self-discharge, but let's ignore that for now. So, if you take this charged capacitor and apply it to a load, suddenly the electrons have somewhere to go - through the load to the plate lacking them. This continues until balance is restored and the capacitor is discharged.
Unlike a battery, the voltage provided by a capacitor is determined by the voltage used to charge it. The voltage printed on the side is just its maximum rating - the point where the dielectric breaks down and the plates will arc across, most likely destroying the capacitor in the process. In fact, the higher the value of a capacitor, the larger it has to be to handle a higher voltage. Small value capacitors (useless for energy storage) can commonly handle hundreds of volts. Large value electrolytic capacitors (the big cylindrical ones in the video) can handle up to 35V, maybe a little more. There are bigger voltage ones but the point is the relationship between the value, voltage rating, and physical size.
Unlike a battery, capacitors can be charged and discharged virtually without limit. Since charge is not stored chemically, it doesn't degrade through charging cycles. The dielectric substance can dry out and other things can happen to make a capacitor 'wear out', but for the most part, charging and discharging is not one of them.
Unlike a battery, a capacitor can be charged and discharged at virtually any current, basically subject to the thickness of the wires connecting it. They don't need to have their charging cycles handled with kid gloves like a battery. Theoretically, they can handle as much current as you can dump into it or draw from it.
So, why are we not using capacitors instead of batteries already? Storing energy as a static charge is nowhere near as energy dense as chemical storage. The formula for calculating the energy stored in a capacitor is E = (CV^2)/2 where E is the energy in Joules, C is the capacitance, and V is the voltage. In days of old, a large value capacitor would have been of the order of 33,000uF (micro-Farads). Charged up to 24V, this holds about 9.5J or 0.0026Wh of energy. By comparison, a Tesla 4680 cell is claimed to hold almost 100Wh (360,000J) of energy. Note: there are 3,600 Joules in a Watt-hour - it is like converting centimetres to inches.
I recall many years ago when there was a breakthrough in capacitors. It was the birth of the supercapacitor which was nothing more than an ordinary electrolytic capacitor with an extraordinarily high capacitance value. It was a 1F capacitor capable of 5V. It's first application was to solve a big problem in the humble PC, replacing the 'coin battery' (usually a CR2032 or similar) maintaining the real time clock and CMOS RAM that stored the configuration. That 1F capacitor charged to 5V could store 12.5J of energy - wow! Remember that a capacitor stores energy based on the voltage charging it, so that old 33,000uF capacitor charged to 5V would only store 0.4J. So, a supercapacitor is just a large value ordinary capacitor.
In order to improve the energy density, some manufacturers created hybrid supercapacitors merging the ordinary supercapacitor with the lithium ion battery. While they benefitted from a greater energy density, they also suffered from the drawbacks of the two technologies. For example, unlike an ordinary supercapacitor, the hybrid could not be allowed to fully discharge because of its lithium ion battery component.
Going back to the subject of the video, a Field Effect Transistor (FET) is as its name implies, a type of transistor. From reading the articles it is unclear precisely how it is used and how it benefits the supercapacitor. I don't know if it is relevant, but one thing about FETs is that they have a parasitic capacitance (this refers to capacitance that is a byproduct and not necessarily wanted) between the gate and source/drain pins. In plain English, the voltage applied to the gate and source pins of a FET controls how much current is allowed to pass from the drain to the source pin. It's a bit like a tap where how much you turn the knob determines how much water flows. The thing is that the gate is insulated from the source/drain part in the same way that the plates in a capacitor are physically separated. The FET uses the excess or absence of electrons induced across the gap to choke off or open up the flow of electrons. They may be employing this aspect in their new design or it could be something entirely different.
So, these scientists have a huge gulf in energy density to jump. The question is whether they have done it in one go or simply taken another incremental step towards closing the gap?
A watt is one joule per second, so 1 W-h is 3600 J or 3.6 kJ. Thus 100 W-h is 360 kJ. In like manner, 9.5 J is 9.5/3600=0.003 W-h.
@@lxoxrxexnx , of course you are right. I was so accustomed to working with MJ and kWh, I just used my usual 3.6.
I will go back and fix my comment. Thanks for pointing out my mistake.
@@briancampbell179 you’re welcome. I didn’t check your other numbers and results, but I rather think they are accurate or accurate enough.
Yes, I googled it as well. Not only that, but the graphics they use are mostly unrelated to the actual topic (and the ones Sam uses are too... I think he *accidentally* included a graphic of an actual super-capacitor in one or two places, but most his video references were of normal capacitors).
So basically all the media is creating a word-salad of nonsense with very little real information inside it. There is only one actual graphic (the one showing the MoS2/SiO2 and FET). Brings back memories of the "nuclear battery" nonsense a while back.... people forgetting the ultra low currents those things generate.
But back to the FET. I couldn't find a deep reference to what they were actually using the FET for, and none of the graphics shed much light either. It clearly is not being used for current control. The implication from the very poorly-worded media description is that messing with the gate is changing the capacitance between the electrodes (MoS2 on one side and SiO2 on the other). Which sounds interesting, but is kinda worthless on its own.
This will also depend heavily... very heavily, on the voltages involved. Super-capacitors are pretty much universally less than 4V but gate controls tend to universally be more than 5V. How they are supposed to pack the layers together into something dense enough to be called a super-capacitor, I do not know.
Hi Sam its interesting but how fast can it be charged from solar
Another name for a capacitor that stored more energy than a Lithium battery would be a bomb.
Unlike batteries when a high capacity capacitor fails it releases all its energy instantly.
A 75kw car capacitor going off would release about the same energy as a 155mm artillery shell.
So a few of these in my scooter would give it unparalleled acceleration at the traffic lights,then battery would kick in energizing the supercapaciter for the next stop/go.this is the same as aviation take off,or e car efficiency
There is a problem with high speed charging of battery packs and that is the amount of energy that the grid can supply. If you take the average house electrical supply in the Uk (80 amps at 240 volt or 19.2 Kw) a 50 Kwhr battery pack will take around 2.5 hrs to charge from low and this does not allow for any use in the house. You could use public high speed chargers but they are expensive per Kwhr as the company running them want to make a profit. If you are able to charge your car in 3 minutes (say 50Kwhr battery - it does not matter if it is Li ion or supercapacitor) you need a supply capable of 1000Kw (1 Mgw) or the average daily use of 125 houses. The idea is good but ulta high speed charging will present major problems for the grid. If you have a charging station of say 20 chargers they will require the energy capacity for a small town. One way to allow high speed charging might be to limit the time of day it can be done.
The grid capacity issue can be overcome by having local battery storage with the charger. The big problem is the connection to the vehicle. Can you imagine the thickness of cable needed for a 2 min charge!
For a 3 min charge on a 400 volt system you are looking at around 2500 amp. To put that in context the current 350 Kw chargers charges at 875 amps. These charging cable can be a problem now so a cable twice to three times the size would be impossible to handle. @@petewright4640
I think ot is an interesting development. There is a growing body of literature that suggest that Li-ion battery technologies and supercapacitor technologies are increasing evolving to a common median in terms of capacity to performance ratio and function. I don't think we'll get as far as replacing EV batteries with ultracapacitors completely because the features and use case of both different. But there have been many stories in the past of complementing EV batteries with capacitors to more efficiently capture and release energy when accelerating and decelerating the EV, because the efficiency amd potential performance is better than what batteries can achieve, without thermal issues to.the battery. So combined as hybrid battery it could make EVs more efficient. Other ideas have been to replace the 12,24, 48 V EV battery with capacitors to improve longer performance over time. Weather and cold impacts capacitors less, which makes them more ideal for that purpose.
I can also see ultracapcitors greatly improve inverter technologies for consumer grade products and pcb use and in EVs to make more compact products at less weight and cheaper price to build, which improves space and weight savings. And of they have better thermal properties they could potentially also greatly improve consumer grade electronics with less risk of fire risks for consumer based products.
Really need the stats on this capacitor, what is the watts per kilogram? What is the volumetric density? Ultimately if you made them to fit in the same battery space in an EV as a conventional lithium battery would it heavier and / or would it have the same or better range? Capacitors tend to need lots of space and low energy density which is why you don't see many of them powering anything by themselves. Also how long do they hold a charge?
I built a car battery from supercapacitors (schematics and build description on my youtube), as well as several flashlights/lanterns some years ago. Another advantage of supercapacitors missed in the video is though batteries support thousands of cycles, supercapacitors support millions of cycles, and are not affected by the heat/cold our weather can produce. If they can get energy density (super cap current weakness) up high enough for EVs, then the supercapacitor could in theory last the lifespan of several cars being moves from one car to the next!
Super capacitor have high self discharge behaviour, while battery not, its major difference, so when you have high energy density of super capacitor its useless if you have long delay gap between charging and discharging, for example charging now and use electricity next day or next week
@@teknosql4740 self discharge depends on the quaility of the supercapacitor. Some cheap Chinese brands (like Green-Cap) are pretty poor grade, and discharge 20%-30% in less than an hour. Then you got brands like Maxwell (I use in my flashlights). Some of their capacitors had +90% charge after 6 months. If they can get the energy density of supercapacitors near batteries you'd have the perfect power source.
The main benefit of Super capacitors is they can store a very large amount of charge, but normally discharges at a faster than usual rate, which is good if you are accelerating a car, but not so good to run as a battery
AGREE 100% that capacitors are the way forward.

But people say…………….. th darnedest things
Charging not only limit by battery, grid and charging system are limiting it so even if the battery can charge in 2 min you will need 3000kw good luck with that
I could see super capacitors getting incorporated into future hybrid battery technology. Theoretically they would be better than NMC and LFP for regenerative braking, pound for pound, in a performance vehicle
I believe that this is was being considered for the Pininfarina electric super car but see no mention of it on the Wikipedia page for the automobile. Perhaps still a possibility or just not itemized there, but more likely had to be scrapped due to complexity or cost, viability etc.
Morning mate
Maybe using lightning strikes charging a flux capacitor might already be patented? 😄
Another "game changing energy storage device"? So many I don't even know what game we are playing anymore.
??? Price ??? Energy Density ??? Ease of manufacture ??? Supply of bulk Graphine ???
That energy density sounds too high for be real.
That's because capacitors are based in electrostatic charge, not chemical based in ion exchange. The electric field generate problems that limit a lot the total charge in the capacitor that makes extremely dubious that supercapacitor can reach so high energy densities.
Speaking of "X%" is doesn't said too much, as it depends of the base value. If you are taking a regular capacitor as a base, 5000% is not even enough to reach lithium-ion or even sodium-ion energy density.
Of course, the high current that a supercapacitor can reach make it a preferred technology over batteries on some scenarios. But for high energy demand, like aviation, high energy density is a requirement, an even current market lithium-ion densities are not enough. So supercapacitor have even less potential.
There is a possible cheat here. Because they are speaking of ultrasmall capacitors, maybe... just maybe, they reach that values because they aren't close one to another, so the electric field is not a problem. So while they have reach "absurd" levels of high energy density, they have a scalability problem to make big batteries. Just putting a lot together won't work.
Which makes me think if it's possible build positive charge (lack of electrons) capacitors to compensate, so a big scale supercapacitor where made of internal positive and negative very capacitors, making a macrocapacitor of zero net charge.
Is it that possible? I don't know.
Besides, if the density were so high, it has very little sense to focus in reach even higher densities were the problems to turn into real products are raw material costs (gold?... not a chance for massive production) and mass manufacturing.
So I think that this ultracapacitors can have very high densities for capacitors standards, but I doubt they are in that values.
If it's confirmed (which I doubt), they they are missing the right focus, that it must be reducing the costs which means cheaper materials and new ways of production to reduce the cost and accelerate the manufacture process.
It would charge faster than a petrol or diesel at a pump

Wow another game changer video. How many games do you want to change. Reading an articulate like he’s an expert. Can’t believe anything until it’s released as a product/ working in real life. If it works and he claims then it there will easily get investment for mass production. Also how many solid state batteries have you actually seen in a product? Answer zero!
I believe certain technologies will advance and make obsolete some of the current ones, just as the moment in time cassette tapes replaced 8-track tapes and then cd's replaced cassettes and now we are here: streaming straight off of the internet and almost no one continues to buy cd's or lp's for that matter. They still exist, but the masses have adopted the new tech. That day will come. No one knows exactly when or where, but it will arrive. I personally believe sooner (1-3 years) rather than later (15 years)
But vinyl has had a resurgence. Who knew?
They haven’t been able to scale these things
Private take up of evs in the UK is tanking. Only massive tax payers funding keeping registrations afloat for corporate and fleet.
Keep it up Sam, but super capacitors? Yawn... I'll get excited when they make it to mass market and they can store even just 10% of a lithium battery. That said lithium capacitors are quite interesting.
The magic black box that provides power to our vehicle motors in 10 years and gives us "range anxiety free" 1500 mile ranges even in large SUVs ... may not even be called a battery anymore. When vehicle ranges are so great that almost everybody can do their entire round trip vacation roadtrips without EVER charging up on the road ... today's supercharger network will go the way of the phone booth.
Some sort of supercharger network will be necessary anyway. For instance, right now, my electric supplier offers 22kwh total off-peak overnight. So much more than 1 night charge to fill up my EV.
This won't change any game. Capacitors energy density per volume makes it a sideshow at best.
Unproven technology still being developed is not game changing. It's game changing when it's proven and then investments in a factory are made, the technology is scaled up and shown to be practical and profitable. Until then, it's an interesting science story with wonderful potential.
For many *decades* we had electric vehicles that transported us around town without any batteries - and yes, I was just a kid when I rode in them. I'm old now, but we had a whole system that let us go anywhere for a low price. But like idiots we gave it up in order to have our own cars. Now we're trying to go back to electric vehicles and we're forgetting that we were already once there. ☹️🥺😥
I remember the Cleveland, Ohio electric trolley cars in the 1950's.
EVs are a bit of the best of both, e power off the tracks
Those electric vehicles of which you speak had a serious limitation: they ran a fixed route on a slow fixed time table. FSD taxis will pick one up on their own schedule, take them to whatever their destination, attend to someone else, and another one will pick them up. Rinse and repeat.
There will be no need for tracks or other overhead charging infrastructure. I believe the cost will drop below 10¢ a mile.
