Hi! Aluminum metallurgist here. Typical aluminum foil is made with a 3XXX alloys (like 3003 or 3004), these alloys are high in Mn. I would like to see this batteries with either a 1XXX (close to pure Al either 1100, 1350 or 1199) or 4XXX (alloys series high in silicon like 4032). I figure both of those would have better conductivity.
could you help me out Michael? I know it has been a while since you posted this, but I have some questions. as, I am also a metallurgist, in the making. XD could you tell me what alloys aluminum foil, aluminum irrigation pipes, aluminum cans and aluminum powerlines are made from? all info would be helpful.
These experiments are a great new addition to the channel! I personally still love the chemistry videos, but these are great for showing real applications ofchemistry. Keep up the good work!
what's more important if such experiments were to be implemented we would solve the problem of polluting the planet,specially if such battery would last almost forever. But something that last almost forever would kill capitalists and capitalism!,which on my humble opinion its good thing!,and captalism should be a crime punish it with death penalty since capitalists corrupt politicians. And people pleas spare me capitalism its good thing since what capitalists today profits on are inventions made in other centuries by true scientists,not forgetting chinise takes things built on youtube by other people,change few things and sell these copied things like their inventions!
Excellent video! I'm glad you're providing narration again and I wish you would release your Russian videos of volcanoes with English narration too. They look Awesome! I miss the ending music with your cat to, but I am delighted your voice is back!
You don't need to apologize for the crude way you cobble your parts together. I remember seeing one of the first particle accelerators at a museum. It was hammered together with sheets of copper. All of the handmade projects look like that. Yours is actually one of the best looking ones. Great video, btw!
Making a battery with aluminium foil, a solar panel with toothpaste. Great experiments... Wait... are you preparing us for some kind of natural disaster?!
Hey, my friend,!! I'm SO, HAPPY" YOU HAVE STARTED, TALKING AGAIN,!! I really appreciate you telling us, in English, ALL ABOUT WHAT YOU'RE DOING, & WHAT IS GOING ON CHEMICAL REACTION WISE.!! THANKS FOR SHARING YOU'RE KNOWLEDGE.!!! GOOD 👍😊 VIDEOS,!! & GOOD LUCK WITH WHAT EVER YOU DO IN THE FUETURE.!!
you should use way more thinner materials, that would result in a way more effective battery. Besides the Aluminium foil, use washi (japanese very thin paper) and graphitefoil. The layers should be as close to each other as they can. If the Graphite foil is thin enough, or has a very thin metallic support, you can roll the packet tightly together to make the battery. Also use potassium hydroxide as electrolyte.
Potassium hydroxide is highly caustic and would likely disolve the aluminum. While yes, it is a powerful electrolite and or can make a potent electrolite solution, with such thin aluminum I would be concerned.
What? The force it can withstand is limited by the shear stress of the threads of the bolts. The hydraulic component is useless. It could be capable of exerting a thousand tons of force, but the moment that you exceed the shear stress of the threads, they break. So you might better use bigger diamèter bolts and a long spanner, and forget the hydraulic jack. It's important in diy and professional engineering to see where the weakest link is. The design offered in this video is daft.
@@raykent3211 the jack speeds up the process of tightening the bolts, he jacks up the jack and then finger tighten the nuts, after that kiss it with a wrench a few more turns and done!
Well done, better use washing soda Na2CO3 or Pottassium Carbonate K2CO3 in water as the electrolyte only. Then it will last longer.. Also adding MnO2 to the carbon will help and you need to put the carbon electrode not in a sealed bag, but this way, that air comes into the carbon, as it a metal air battery...you can also use use a stronger oxidator like KMnO4 on the carbon, so you supply the oxygen without the air needed...then you can seal it up again...Hope this helps...
Very good. Easy step by step proces explained . Basically you use ReDox reactions with metal and salts. The energy from chemical to electricity. Most batt are so. But these are storable. ( like those lead/sulphuricacid for car without demiwater added.) I like the simple household material use.
It’s an emergency! 5 hours later (add 12 more if you don’t have a blowtorch)... woo! Almost as much power with a dozen of these as a very small crank light/generator which works all the time! Interesting concept, but it’s only like 2.5 to 3 watts max (from the 5 packs put together), and if it only lasts 5 hours then that’s 15 watt/hour. But for this much work you might as well get a pocket sized crank generator or if you really want, make a bicycle generator (I’m ridiculously scrawny, but if I were just super leisurely pedaling for a 10 hour day, maybe like powering a laptop or desktop, I would probably average at least 100w, it seems like that would be much more useful since it will power much more and always be at the ready, and re-usable, and can be powered by Tacos, plus it’s just as easy to build and probably with more common supplies like a drill motor (or anything DC), and then a bicycle or exercise bike and a rope/belt/rubber bands/fabric/shoelaces etc). I wouldn’t even own half the materials he uses anyways. Cool concept, but certainly not “perfect” for anything, let alone emergencies! If I need power in an emergency, I’m not carrying a syringe of salt water! And if I packed DIY battery pouches, I’d rather have a USB output hand crank or any of my other batteries (the small LiPo packs I use of similar size and voltage would be capable of of about 100 amps continuous and 200 amps peak compared to the 0.75 amps max he had shorted (I’m guessing mine would be over 300 amps likewise shorted, but it would be some eventful arcs and glowing wires in about 1/2 second though, so that makes it difficult to measure, haha!), so those batteries can actually do something useful, you would need about 12 of those cells shown in this video to slow charge a cell phone at 800 mA, so that’s not really “useful” amount of power for an emergency (and Id say charging a phone for help is an emergency).
Interesting. The press might be too elaborate. Nuts and bolts, if you think about it, are basically screw jacks over and above being fasteners. According to the equations: (2*pi*f*R) = F/pitch. Definitions ---- pi = 3.14 (about), R = radius of lever arm, f = force applied to the lever arm (in foot pounds); F = force (either push or pull) of the nut/bolt set up, pitch is the number of threads per inch. So if you have an electric drill that stalls at about 6 foot pounds and if you have a bolt/nut combo that has 28 threads per inch then the F might be something like 6 short tonnes. I think that my math is approximately right --- you can wheel on over to Wikipedia to check it out using a scientific calculator.
Nothing free about his project given all the stuff that is required. Aluminum foil is also not free, nor is the jack, drill bits, metal sheets, chemicals, etc. Nothing is actually free other than people to make choices
@@AaronSchwarz42 salt water is free recycled metals are free copper can be free from stripping a bit off wire or even penny's.. alluminium foil is what £1.50 enough too do hundreds off batts with depending your build there is many things you can get free or get your build cost per unit like a few penny's each...zinc is free in old batteries you can use vinigar which is 30p a bottle enough too do alot with you can look for scrap copper pipe and brass taps or even foil take away food containers not hard too spot there's all sorts if use your head but really it's about cost effectiveness and these such materials n builds are hugely cost effective
Im wondering if the hydrogen is being absorbed by the graphite creating an electrochemical process boosting your output. You may have a hybrid battery/fuel cell there with the sodium hydroxide / aluminum chemistry
A word of wisdom to make your life easier.. unless using carbide drills, drill at a slower speed with plenty of pressure and a little bit of lightweight oil making sure the drill and the steel arent getting too hot. This will help make your bits stay sharper and cut through the metal faster
Rule 1 of youtube: if the title has lots of capitals and an exclamation mark, beware, it's probably junk. Sad in this case, because I'm confident that the method would work, yield the results stated and I enjoyed the video. Not a scam. The author should take note. The title hype and misdirection is intended to attract but has the opposite effect on less naïve you tubers. I would have ignored it if the notification hadn't arrived when I had half an hour to kill.
After the fall of modern man...people will be wishing they had watched this video man and won't care that your method is inefficient..it works..that all that matters bro.
Very cool but alot of work for 5hr listening and I think not very practical in emergency...I suggest a video on alternative simple batteries..copper pennies and aluminum with a salt electrolyte..simple fast and can be made without complicated presses etc...love your videos
I lived near Lincoln Park in Los Angeles for about 3 years recently. The actual park is called "Plaza de la Raza" after the Mexican Revolutionary Ideal that a mixed peoples are more vigorous and cooperate better with each other.
That depends on the total wattage generated, and if it doesn't get generated fast enough then it'll depend on the watt-hours generated and whether you have a way to store that.
This build is very similar to a disposable hand-warmer product that was on the market in the 1980's. The electrolyte was stored inside the packet, but was encased in a wax vial, which you would crush or snap in order to activate. The only overall differences were that the entire was wrapped in batting, in order to prevent burning, and no electrodes, as the energy was left to create the heat within. I think they only lasted about 15 to 20 minutes, but would make your pocket, glove, boots and/or hands quite toasty. I think they were called "Hot Shots" or something like that, although the venture failed apparently; however - the product DID work. Interesting segment! I was unaware of spray graphite until now - good to know...
I make it, and use NaCl or table salt 10mg in 100ml water. I think if we can completely seal the battery package, it will very reliable for survival situation. Okay, I use Joule Thief toroidless for load, and it give me usable light for 10 days non stopped. Great DIY battery for me, so easy to make! 😃😃😃
The experiment alone was quite interesting, at least to simply 'demystify' the usual plug and play block (battery) we usually use and take for granted. Electricity have quite the many sources besides the ones we are used to.
Thoisoi, I'm glad you have expanded into making batteries, this has been a fun (but also sometimes frustrating) activity for me for many years now. I have also built similar batteries, but I don't believe the half reaction at the cathode is the complete reduction of oxygen, this requires sophisticated catalysts on the carbon. Instead, I think the oxygen is being reduced to its superoxide: O2(g) + H2O + e- => HO2- + OH-, E° = -0.065V (J. Phys. Chem. Ref. Data, Vol. 18, No. 1, 1989) The half cell potential is not good (which is why you observe the overall lower than expected cell potential), but it proceeds kinetically quickly because no bond breaking of the oxygen is involved and so activation energy is very small for this process, it's essentially only electron capture by oxygen adsorbed onto the surface of the AC and doesn't need a catalyst. Also, I don't believe that the strongly alkaline version of the oxidation of aluminium is the correct half reaction occurring here (because 'reasons' lol), I think a more appropriate equation for aluminium oxidation under these conditions is: 2Al + 2H2O => Al2(OH)2(4+) + 2H+ + 6e-, E° = 1.60V (J. Phys. Chem. Ref. Data, Vol. 18, No. 1, 1989) When you correct for your pH using the Nernst equation, I think you will find this comes very close to your observed cell potential.
Try and put the aluminium foil on mash as an electrode. That way the circuit won't get cut off as the aluminium dissolves. And maybe take apart the rough mash and make a wire out of it, so you could seal with heat the top part of the battery.
What do you think the very best electrolyte for the battery? How can we know the AH of the battry bro? And after discharge are we going to charge it with same volts supply?
The best electrolyte is probably proprietary. To get amp-hours, hook up an ammeter, and film the meter with a camera until it reads 0 amps: then calculate the integral. As far as recharging goes, these are _not_ rechargable: maybe if you replaced the air and water with something else (and even then you might need to keep it really hot), but _not_ with an aluminum-air battery.
Use magnesium and manganese oxide (out of any alkaline battery) use a carbon rod as a current collector And you get high current 1amp and greater, and around 2v

Surprised that the epoxy didn't work as an insulator as you spread it completely over the surface. Awesome result though - very well done :)
The secret is to force the pieces of carbon into contact with each other, and keep them there, while the epoxy cures. That's what the press was for.

I was worried that we were going to lose you when you were baring down on that homemade hydraulic press.
Thoisoi, I'm glad you have expanded into making batteries, this has been a fun (but also sometimes frustrating) activity for me for many years now. I have also built similar batteries, but I don't believe the half reaction at the cathode is the complete reduction of oxygen, this requires sophisticated catalysts on the carbon.

When you correct for your pH using the Nernst equation, I think you will find this comes very close to your observed cell potential.
I have a question about how O2(g) can come inside the battery and react with H2O? It may affect the long-time battery life too.
Magnificent work! Thank you! 🍷
That's actually a pretty solid press! Great video!
Would it be better to use those power tool battery? Would it be easier to use those bolts to tighten down w/o press?
Try and put the aluminium foil on mash as an electrode. That way the circuit won't get cut off as the aluminium dissolves. And maybe take apart the rough mash and make a wire out of it, so you could seal with heat the top part of the battery.

As far as recharging goes, these are _not_ rechargable: maybe if you replaced the air and water with something else (and even then you might need to keep it really hot), but _not_ with an aluminum-air battery.
Thanks
4h worth of battery for 40min *4 batteries... Very, very nice!! And cool experiment
Use magnesium and manganese oxide (out of any alkaline battery) use a carbon rod as a current collector
And you get high current 1amp and greater, and around 2v
Is this batery rechargable?
Can these be Recharged?
