- A 4 farad 1.2v graphene supercapacitor and how to make it step by step. You can buy kits and materials for your own experiments as well as my ebooks from our webshop at secure.working...
I thought no one was making videos that perfectly explained these convoluted things. It makes me happy that people are showing how to make these basic parts of very cool new technologies
cheers mate
New lol 😂😂
When he announced "4 farads" it genuinely made me smile. The future looks bright.
awesome mate lol
My left ear enjoyed this video...
that'll be the one to use then
Uh, that was left? I've reversed my speakers then.
I thought it was 1980 mono tv
Hey guys take it easy just enjoy....lol
I did enjoy it, very much actually. But only in the left ear.
LOL your laughter at the achievable scale of these things despite almost no care or precision taken, is infectious. Think I'm going to have to go back over some of your earlier vids as a primer and give it a go at last. I've been merely observing for too long.
+TheBaconWizard good man - let me know how you get on
+Robert Murray-Smith I will do :)
+TheBaconWizard cheers mate
@@TheBaconWizard Well, it's been three years now? Guess the capacitor roasted the bacon wizard.
STOP🤨🤨🤨🙏🙏🙏. Be warned… if you subscribe and try even ONE. You’re gunna get got. I have a whole kitchen slowly turning into a laboratory and a gsmall group of neighbours that are convinced I’m “not normal”.
Also… your going to have (to use the Australian vernacular), a “shittonne” of fun 😂😂
This is one of the most important videos ever made! I am damn serious about that assertion.
Damn right! Now how about this question? How do we know that the GO is actually graphene oxide? That would certainly account for why the AC does so much better, right? We really do know that the activated charcoal is as advertised. The GO....not so much. We really need a bodged together Raman Spectrometer in here!
It's good to watch these old videos from 2016. Full of great info :)
I know I've said it before, but truly love watching your videos. Mainly because you are such a big kid!!!!😜😜
+Eflat Productions lol cheers mate
I don't know if I would word it that way as I wouldn't dare risking to offend him, but I would agree that RMS is having way too much fun! I'm thinking he must be single, but if not I'd like him to explain again how he exfoliates graphite in the microwave.... without getting scalped by the wife that is.
lol - i am married mate - there are quite a few videos on microwave exfoliation 'a' does a really good one
People may be wondering why you're laughing. Not many years ago a one farad capacitor was pretty much unthinkable on a practical level. To be able to make one in 5 minutes using pennies of common materials from your house is unimaginable.
It's the electro-chemical equivalent of being able to make a smartphone in your tool shed for $5.
really nice way of putting that mate - cheers
You can make a smartphone In your toolshed for 5 dollars
Davey Hi his laugh was contagious. haha
Standard capacitors of that size are 1,000,000th the power.
I remember solving physics exercises and having to restart calculating from scratch when getting a result in farrad class because it was unrealistic and when you get a result not in uF or nF you're almost certain that you've made a mistake and have to start from scratch.
This video was the spark which ignited a raging fire. (Not literally) I have watched it and shown it to so many friends. My obsession with building supercapacitors marked the start of a very wonderfully strange chapter in my life. the one thing that I was inspired to try was to use “neverwet.” As a separator on carbon fiber veil that has been lightly electroplated with either Au, Cu, Ni or Ag. using sodium silicate as both a binder, and electrolyte; when mixed with a very small amount of grapheme oxide and acetone and doing what could be interpreted as a supercritical drying process, by freezing it, and subsequently baking it @ 250-450f in a (homemade) autoclave under the highest vacuum I could generate with a couple of reversed air compressors and a refrigerator pump , the whole thing puffs up like breakfast cereal, and hardens. Technically; I believe it falls under the definition of solid state but I don’t have any collegiate education, so its highly likely I’m wrong about that…(I later realized I had made a kind of grapheme/silica aerogel) it was solid state but in regular atmospheric conditions(I live on the rainy side of the big island of Hawaii) it would melt after a few days. I also tried this as a bastard version of the “crystal battery” which has been used in the TH-cam community by many, for a long time. This tiny device seemed to charge itself. Unfortunately the majority of my toiling was destroyed in the 2018 LERZ eruption which ate half of my neighborhood, and proceeded to melt a few more including the town of Kapoho, the largest eruption in the recorded history of Hawaiian islands. It also added an additional 18 acres or so to the island after filling in Kapoho bay. The lava was extremely liquid, and at one point it measured almost 4000 degrees Fahrenheit. I have been working as a guide in the ocean and on land for a dozen or so years taking tourists to get on top of and adjacent to active lava-ocean entries. I have never measured lava more than about 2700f. My point is that there’s an awful lot of elements that came to the surface in my neighborhood and have been oxidizing in different layers for the past 4 years. The lava was 120ft thick in some places(will be cooling off for the next 20 years or more)but it is porous and has seawater leaching into it. I’m wondering if the flow fields may possibly be able to hold a charge…there’s a geothermal power plant that just so happens to be surrounded by the new lava… I find it very intriguing. I have 2 children who are 3 and 5; I rarely get the opportunity to talk to anyone who has the slightest idea what I am trying to say…what do you think?
"kitchen paper, because it's easy to get hold of" good times, good times.
Bbbbbb
Your channel is giving me flashbacks to the days when BBC used to actually be educational. Thought provoking content that encourages us to explore the perpetually uncharted world of tinkering in our own garages and kitchens? We haven't had that spirit here since 1969! lol. Hats off to you sir and thank you for the inspiration. I really appreciate your enthusiasm in your presentations. It's contagious
I love your videos and how you share your knowledge with others. To those who criticize you in any way are nothing but complainers, not contributors.
Hello Robert, I just wanted to say I have been putting off opening a google anything, BUT I did cause I APPRECIATE all the effort and commonsense you are able to impart to anyone willing to get their hands dirty. SO>>>> Thank you for your time and efforts. GREAT job
RMS, you're truly one of the greatest of all time.
-joshua bertrand
Absolutely amazing that such a high capacitance can be produced so simply and cheaply!
i think so too
And there was I, thinking that you'd need all sorts of clean-room conditions and highly technical and expensive processes. Thanks for that, subscribed! I shall be watching a lot more of your videos!
cheers mate
its all about how u use basic science to do complex designs
no fancy stuff required
if u have the mindset and wisdom u can do anythink
i agree mate - well said
Thank you Robert, not for only answering my question of "how to" cleanly and clearly, but inspiring me to experiment and find tomorrows technological break-throughs thanks again great as always keep it up!
awesome mate - I am glad you found it useful - cheers
I think you have a fantastic ethos regarding try it yourself, change the recipe etc. That is the way I have always learnt, often more with failures, but persistence is the key to success. Keep up the good work, you will make that million.
+Martin Counsell lol - cheers mate - what is it Edison said 1% inspiration 99% perspiration lol
Four Farads is a crazy amount with only 2 plates and a few grams of materials! Mind blown!
Great...marvellous video, Mr. Murry-Smith!
Love and peace to you and your beloved.
I so love watching your videos. I was interested in science as a child and was learning from a teacher that reminds me of yourself. Having someone with such a infectious attitude of teaching is grand. I was transferred during my middle school years but never found a science teacher such as yourself that was so knowledgeable of his teaching as much as you. I find it is never too late to learn. Thank you so much for your videos. From across the pond Hello and have a great day.
hiya mate - thanks for taking the time to write and say that - awesome my friend - cheers
Thank you so much for not editing the waiting period out! LOL
By the way, 3rd viewing. We all need to watch at least 3 times.
Superb video, outstanding results
Imagine banks of these to fill a building for storage of PV solar driving inverters, better yet no inverters and use the D.C.directly
+Craig Nehring that would be cool - get building lol
Hello, you are doing a very interesting job, but more valuable is that you share the fire of the heart. Good luck with your endeavors and good health to you!
I just want to thank you for this video! Been wanting to experiment with making a super capacitor power storage system
+Kevin Hughes (netsplit) cheers mate - good luck with it and keep me in touch with how it goes
So touching to listen to your enjoyment upon pondering the measurements. thank you for your consideration to teach. the video was crystal clear and well done With tons of highly informative research. This is undoubtedly the best technical video I have seen in the last number of years. This was recommended and I couldn't have imagined the value. So it was quite encouraging. Funny I was searching around asking about measuring large capacitance meters and was told they did not exist. Glad that was wrong! Cheers!
thank you for taking the time to post and say so mate - cheers
This is all new to me,
I'm fascinated watching your experiments, particularly the Hemp and Graphene battery.
I wonder how many businesses (big and small) have approached you?
Anyway, keep up the great work, thank you from Australia.
Really astonishing on table top without any messier a 4 farad grate... on the face of others who make it so delicate and something that can be manufactured in pricey labs...
just think of all those greats who did wonderful work without pricey labs - exploration of ideas doesn't need a great deal of money
Very well said .... I belong to India from a ruler back ground ... I was fortunate that I got chance to study and become capable to earn bred ... but when I go back I created people and villages having less electronic... still they just have 4 hr in full day ... I always think of doing things that could benefit them ... so I keep on reading and understanding things that can help them ..
Like super capacitors ... they can charge fast ... but the thing is that they can with hold that like battery... I constantly look beat of both worlds... they can charge fast .... with stand the charge like battery ... cheap so that all people can afford and can solve there real life problems ....
i always try to make things that can be produced any where in the world with a minimum of machinery - if any at all!
Incredibly inspiring, i am so happy for finding your channel.
Like the modern day Professor Laithwaite. Thanks very much.
lol - cheers mate
Thank you for sharing your knowledge.
+John Allen cheers mate
A very good learning and knowledge gaining vedio for learners
Top notch tutorial, Appreciate your time and effort, sir
That's pretty amazing
I have watched this 3 times now and it still excites me 👍🏻
Thats 4 times now 😂
thanks for sharing all your know how. I don't think the wives and mothers like it much though. I can never stop watching.
lol - awesome mate - cheers
From the title I expected something simpler but it is very informative
That is outstanding!!! I'm going to make some of these and see how they charge with my Bedini-starship coil energizer. This is really useful information, and a must try. Thanks for this amazing video
Bravo. Well done and great work stimulating both the young and the old. Experiments do not have to be hard nor exceptionally complex, just well thought out. Hint, use the noodle...
+BluesDoctor cheers mate - and absolutley
I am saving up now, so I can buy one of the kits from your shop!!
And I am going to have Sooo much Fun!!
I hope to be off grid within this year!! 🙂. XxX.
fantastic - clear explanation and fun - yes experiment the components are there so why not... how exciting - really this just opens up a whole new world... thankyou
cheers mate
nice one bought your e-books too, Graphene and supercapacitors - a good excuse to build a kiln in the backyard methinks... love messing with fire bricks and acids... Are you still making the ink for sale?
no mate - but i did a couple of videos on how to make it for yourself
awesome yes I have watched - very inspired by your work and knew I would just have to try something from your vast pool of info... I'm loving the graphene intercalated compound film at the moment, although handy little amounts of aluminium chloride have proven hard to come by in Australia I do have a source albeit expensive - saving pennies...
you can make your own by dissolving kitchen foil in brick cleaner - aluminium in hydrochloric acid - google will help with directions
I would go back to school to take courses from you Robert. This video was great. I love learning from you!
cheers mate
How does this only have 125k views......
TH-cam CEO is a SJW-Femminist
SJWs dont like useful videos ;D
I love this video. When I was working with electronics in the 80's, if we needed a capacitor even close to one fared, we would use an amplifier circuit to simulate it because such a large value capacitor was a practical impossibility. Now you can slap one together as easily as any Mod Podge craft project.
Never stop, Sir!
+Neil Smith cheers mate
I love all your videos, very informative and extremely easy to understand. You make a great teacher. Unfortunately I can hear what you're saying in this video and I'm excited to learn about this. Can you please add subtitles?
Please disregard, it was my phone acting up
I love the cackle hehe that is impreasive capacitance for such a small package.
That shows that carbon must have huge surface area.Very good demos thank you.
cheers mate
That's awesome, sir.
I am a computer student with nearly little or no knowledge of chemistry.
After a little study, I did try heating up graphite powder in a ceramic bowl with 43% phosphoric acid and a few drops of dil. h2o2. What formed was a spongy light grey residue. Don't know if there is any graphene there but there was remarkable increase in conductivity compared to the dry graphite powder. Kindly, cast some light on what must have happened. Thanks and regards.
intercalation
So if I am understanding this right your 4 farad capacitor, translated into size comparison to those capacitors you find in a clock radio for example, would have to be the size of the Kitchen roll you have there. (depending on the voltage used)
sounds about right mate
Great vid Rob, full of step by step information as well as many tantalising ideas hinted at.
I really must make the effort to replicate your experiment and hopefully come up with ideas along the way.
All the best - Martin.
+solarhope - you discover by doing mate
The content of the video is so amazing, but the quality of the video is so blurry it's really sad. We should all pitch in and buy you a better video camera so we can really see the details of what you're doing.
And better micro (two channel at least). But all an all video is great!
I didn't even notice lol
I'm using a 13 year old thinkpad with a 1024x768 display
A closer view of the detail things would be excellent. I often watch from my cell phone and the TH-cam app will not allow me to zoom in or at least not that I have found. I used to be able to zoom but about 8 months ago something changed and I can't anymore. Bummer!!!
So I true. I second that emotion
Personally, for an acidic electrolyte, I'd use gold foil, very low resistance and absurdly high conductivity, and almost nonexistent reactivity
Would cost a lot
Gold leaf ;)
Gold has low overpotential, the working voltage will be less than 1V in that case.
4 Farads on that device? Ok, Officially mind blown. Not long ago I was doing a Fire Investigation and we found hundreds of Capacitors in a Arsonists storage shed. The PhD that helped us on our case said a 1 Farad Cap would be as big as a room. Either I got the dumbest Engineer or I misunderstood what he was telling me.
a farad used to be huge when stored on a cap mate but that started to change around 20 years ago now you can store a farad on around 12 square centimetres of active material - but you are right 4 farads on that little thing is mind blowing lol
I remember watching an older video on capacitors and capacitance and them saying it would take a capacitor the size of a skyscraper to hold 1 farrad, that been said i think that was for oldschool capacitor design
LOL, been watching old videos. I have this standard ~7.5"*9.5" composition book with 100 sheets on it. I calculated ~18A per sheet pair so ~200A per book. A stack of 4-8 books could start a truck. That's between 1/8 to 1/4 of the normal battery size. And this is with just a standard "everyone knows" recipe using kitchen towels.. LOL.
Ofcourse it would take quite a bit of sheets to match energy storages. I'm thinking, big cheap diy solar storage. And above all, safe.
If the long capacitor electrodes are impregnated with an electrolyte, the capacity increase. In some cases, is impregnated under vacuum 24-48 hours. But even without vacuum markedly significant increase in capacity. Thank you for your Vidoje they sparked my interest and now I find it difficult to stay :)
+Karantin Kunz thanks for the comment mate - nice one
I love watching your videos, very interesting and informative, may I recommend a microphone on your coller or something closer to your mouth, your shop creates an enormous amount of echo which makes it very hard to follow what your saying. Keep up the excellent videos, thank you 😊
15:21 sound of silent satisfaction
nothing wrong with a bit of smugness every now and then mate lol
At 4 Farad and 2 mg of material, you would be looking at around 2000 F/g; much higher than your off-the-cuff calculations of 500 - 700 F/g you call out in the video. That just about beats the field far as I can tell.
I did read somewhere that a nickel hydroxide electrode was producing +3000 F/g but given your environment, set-up and simple chemistry, that's downright impressive.
all the info is on the vid for folks to make and verify if they wish mate - there is going to be a difference on specific energy when the final device is put together
Thank you for this I have been looking into building these and have been looking for a good place to learn I think I found that place!
Dear-Mr.Smith....Good Luck in..2017...and YES.hello from Latvia.
cheers mate - have a good one too
Do you think I should make a science fair with this? I would really enjoy the input!
Thanks So Much for Sharing!!! my you live long and prosper!! i will attempt to build a few for sure i have all the stuff now, again thanks so much
awesome mate - good luck with it
Very nice summary to tie things together. Thank you! Experimenting with various sifted carbon grain sizes with various adhesive glue viscosities looks promising. Perhaps even a compressable spongy adhesive to make a variable supercapacitor!
+yougeo i did a video on exactly that mate lol - let me know when you do a video of your experiments i would love to see
This is a great video glad i found it. Thanks for the detailed explanation.
i am glad you enjoyed it and thanks for taking the time to post - cheers
18:05 Makes sense the Activated Charcoal would store more. It has a larger surface area cuz of all the porous holes in it.
Awesome video
Very thorough explanation. Thank you. Just one small detail I would like to mention. The mike picked up a lot of noise form the foils. Something to keep in mind for future videos. Thanks...
That is very impressive
Thank you very much for sharing these information with us . I have several questions. Hope you don't mind!
1.If I connect several hundred of these "SuperCapacitor" in parallel can I draw lets say 100 amps without any dangerous or burn these plates ? And If the answer is yes
2. how can I calculate the duration which these Capacitors can deliver 100 amps (using this formula ---- Ah = F * V / 3600----) or something else ?
3.How much the ESR or (the peak current )?
4.my final question is If I increase the surface area size of these plates the capacitance will increase but the voltage rate will decrease right ?
Thank you very much :)
+Abdulla Qasem no worries
1 - yes
2 - looks good
3 - don't know
4 - capacitance increases voltage remains roughly the same
I've already got a hundred projects, but this video convinced me I want to add one more: research capacitors! :D
go for it mate lol
Robert Murray-Smith Thanks for the inspiration, I built a few simple capacitors over the past few days, just on my desk, and with random materials.. but it's loads of fun! :D
it is indeed mate
Before I was intimidated to make a simple electrolytic capacitors for my electronics 101 class now after watching your videos it looks like I’ll actually make a great super capacitor has one of my class projects thank you for bringing it down to a simple level that’s not intimidating easy to understand. As easy as making a penny and nickel lemon battery 👍
Also as for the layer that holds the electrolyte... The tissue, if holding more electrolyte yields more current and voltage potential then you shoukd look into magnesium carbonate... Gym chalk... I saw an experiment where a compressed block of this stuff was placed inside a container with 8 times the volume of water and weighted down until nearly all the water was absorbed by the block... Now when they removed the block it hadnt swollen in size or become soft... And when they broke inside the block all that water was contained in just a few mm at the bottom of the block... Surely electrolytes can be contained in such a medium
I wish you were my teacher in highschool
Thank you for this video! It is exactly what I have been hoping for in the context making carbon based energy storage. Right now I am puttering with making graphene, and I think I have a couple grams of it, but it's still a little short of being in a usable form. My research in this stuff in forced to take a back seat, right now I am putting together a farm business and that takes most of my mental focus.
I hope to be able to power an electric bicycle with a much larger unit in a couple years, after my LiPoly expires. I think it would be great fun to see one of your large super caps on a bike, that would be a real ground breaking video.
I am curious how great the difference in thickness of active material is between your two systems, and also I wonder what the upper limits are on how thick one can make the active material, and what limiting factors tend to come in to play as one thickens the active material.
+Ray Wharton shame about the delay mate - but good luck with the farm. I was thinking about a bike myself - i might buy one to do just exactly that with lol - I should measure it but it was just a how to make it demo. The limiting factors would be resistance mate - the thicker it gets the greater the distance to the collector plate and the higher the resistance. Attachment will be a factor too and electrolyte penetration
+Robert Murray-Smith lol. I was sitting here pondering the transient punch through V, Q and resistance issues as I saw this post. Downloaded Grafoil engineering guide and thought, quite an engineering trade-space. Permutations offers much room for optimization and plenty of interesting lab work. Amazing what 50 years of quality lab work can yield for things like grafoil.
+BluesDoctor i tend to recalander the foil down to a few microns via a two roll mill - it is amazing stuff and you are quite right there is a ton of work that can be done here
Dear sir wonderful work. I just wish camera and focus was Little better. Keep up the good work.
cheers mate
What is it that you can think of that you know or don't know about zpe zero point energy
Be warned that the power supply people may not want you to let the cat out of the bag
Ha ha old. Love your show
One of the best science shows
You must be a scientific teacher
It would be interesting to know the self discharge and esr parameters.
Good job 👏 👍
I watch all your video and they are great . Can we work on a higher voltage supercapacitor?
We live in an AC world and that's where the scientific challenge is finding a dielectric that can store high energy yet can withstand ac voltage.
Experimenters - remember that if you write down what you did, it's science. If you don't, it's just having fun.
Thank you man, learned and enjoyed a lot
You are a science God... :-)
Great Lecture I liked every step I am keen to know the capacitance of the grapheme supercapacitor.
Why voltage need to be that low? Any chance to build super capacitor that hold 100V for example?
because small ones are quick to experiment with - i have built big ones in other videos
That's a pretty nifty little device for measuring capacitance but I think it's kind of silly that it set up to make you hold the button in the entire time it seems like a hell of a shortcoming in design
Super happy about super capacitance
Thanks Mr. Murray... Brasil ( Guarapari ES)
cheers mate
Awesome - thx so much. Why bother with rechargeable batteries when we could use capacitirs? Anyone?
Hi Mate...
After running the motor until it stops, hook the battery up to your joule thief...I've done this with my batteries and it has power left after running the motor to run the thief for quite some time.....
Initially congratulation for your video and your humour.
Thus to obtain a super electrolytique capacitor one takes a graphite sheet one applies graphite oxide diluted in acetone above, one applies an insulator example a paper paper towel over the oxide coating graphite dried and then one pours some drop of adhesive contact above the insulator and then one gives an oxide graphite sheet impressed of graphite and that it ?
Which proportion of acetone mixes you one with graphite oxide?
Thank You :)
Love your videos! Please continue! - How about a series on a batteries as well? SUPER BATTERIES! :)
I guess you already did that lol thanks! Solar cell then?
+Paul Deschamps lol - solar cell it is -i agree, i need to do that
I love you so much. You are an inspiration....
+DrSpooglemon bless your heart mate and cheers
Could you do the same thing to make a capacitor that has the same dimensions as a button battery? I think that would be a real treat.
That could also make them easier to link together within a system while saving space along the vertical profile or the unit.
I was hoping to get in touch with you over an idea that would have medical benefit.
I have a idea to make a new type of lithium ion battery it has a semiconductor sandwiched plate in the center of the cell it regulates the charge and the discharge of the cell. This prolongs Battery life by regulating charge and discharge cycles and it stops Dendrites from forming shorting out the plates. The battery has 4 connections +and - and emitter and collector these connections control the passage of electricity taking the place of the separator in the cell. The battery is a rolled up cell design.
Amazing.... Good work!
-Nils
sir u are so inspiring........I am your fan.....I remember reading somewhere that voltage in a charged capacitor falls exponentially with time....what is chemical part of a capacitor/battery which is responsible for volts? and what part of it is responsible for amps?
reaction kinetics give volts and amount of material give amps - well bascially
great video gonna make some tonight
Hi I have a question about your carbon powder and binders you are covering in this video. When it comes to the acetone method, are you mixing just acetone by itself with the carbon powder or is there a third additive that is the actual binder to this formula? My apologies but I wasn't quite sure what I heard in the video. My last question is about the current collector materials in this demonstration. Did you use the same current collector materials for both capacitors? If I was not mistaken in what I heard you describe I think you used graphite foil for both capacitors. I'm aware that on one capacitor you used activated carbon and on the other capacitor you used graphene oxide if I heard you correctly. I am wanting to try my hand at this so this and you have covered this in detail and I cannot thank you enough for sharing this information with others. Take care and have a Merry Christmas, Flash001USA...
