Instead of Sodium/Potassium Hydroxide you can use a mixture of Salt and Sodium Carbonate(Washing Soda not the Baking Soda) Washing soda it's very Alkaline but will not attack the PLA
Yes, use Washing Soda Na2CO3 or K2CO3 !
Choline chloride and imidizolium chloride make a brilliant deep eutectic solvent electrolyte for rechargable AL batteries 😉 just add some aluminium chloride, carbon and Nickle or titanium electrodes. Works as a plating/de-plating battery.
Yes, good idea. But is not appropriate for the idea of that project. Because here the idea is to make a easy reusable al air cell that can make most of people. 😉
Very nice, I like the fact that you can change the anode very easily, as well as using just regular foil.👍🏼🙂
Very nice! Simple to build but very effective, I will try this out myself for sure 👍✌
This idea will be useful for further modifications and to make it vaiable for day to day use. Really awesome 🙏
Of those you've already done, would this be the one with the highest current output?
Brilliant! Thank you. Reminds me of the old locomotive where you just had to shove in coal and the magic was done! I don't know how that would perform if I put in a large chunk of aluminium foam metal!
That's pretty incredible honestly
BIG BROTHER THANK YOU FOR LIFE SAVING TECHNOLOGY FOR US.. THANK YOU FOR YOUR TIME 👍👍👍👍👍
Awesome! Does the reacted Aluminium stay in solution or does it kristallise at the bottom? Thanks for sharing!
Fun, educational, inspiring and useful proof of concept.
Good one Cayrex!
Really nice work here!👍
I just had a question regarding the dual electrolyte aluminium air battery you made a couple of years ago. I tried making it a few days back and it seemed to give a good voltage output for a long time but the current dropped out very quickly could you suggest any solutions so I get a better current output for a longer time
Yes this is because of the membrane. To get better performance you will need to use a nafion like membrane
Okay thank you👍
Excellent video. What are you using for the filter paper separator?
Just normal coffee filter paper which I find in the store
What in your experience is the best all round battery.not to expensive not to dangerous good capacity charge .a diy battery
Freakin awesome dude!!
Really nice battery! I've got to make one myself. How how did you activate the carbon felt?
I get the activated carbon. But you can mix some activated carbon slurry and you coated the graphitic carbon felt.
You're gong crazy with that 3D printer! 😊
Emm... 😅
very interesting! thx!
can you tell about the output capacity of this cell. i mean voltage and currunt and time. MAH
HI, very good stuff.
Something i dont understand here, what is the most important, air contact with electrodes (anode,cathode) or air contact with aluminium ?
Plastic spacer? The parts here are + Titanium current collector, activated carbon felt, separator, plastic spacer, electrolyte and - Titanium current collector
Неплохо. Однако следует поменять местами катод и анод. Таким образом, на катод будет подаваться снизу водород из за деполяризации алюминия. Кислород будет подаваться из атмосферы воздуха через "дыхательные отверстия". Катод в свою очередь будет катализировать или как бы "утилизировать" выделяемый водород при помощи кислорода воздуха
Hello, do you know where I can find some of those activated carbon you used? I attempted this project, and though it showed 5 volts on the tester, it failed to power the small dynamo. I suspect the purchased carbon may not be authentic, as it felt more like a foam filter. Unfortunately, I couldn't verify if it was genuinely activated carbon when I bought it online.
Hello! The ACF I get from some company which make sell business to business. But on internet you will ba also able to find some companies that can sell to people. www.ceramaterials.com/product/activated-carbon-felt-sheets/ , www.graphimaterials.com/activated-carbon.html , www.graphiteinsulation.com/product/specialty-felt/activated-carbon-felt/ (ACF 1600 is good) ,
@@cayrex Thanks for the info, do you think using an activated carbon sponge as an alternative to felt will still make the product work?
very interesting!
Great work...
Hey is it possible to put one in a vacuum chamber and see if it still works?
Based upon what I know about electronegativity you should have .9v of potential difference between carbon and aluminum per cell. Is that what you see in voltage of a single cell?
The voltage is from 1 to 1.1V per cell
@@cayrex Ok.. This is what I was working on before I couldn't work no more. If you can protect the electrodes from the galvanic destruction you should be able to draw current from that potential difference. The problem I had was figuring out what would protect each electrode and still pass a good current. Carbon seems to be the answer. The storage mechanism is the disassembly/reassembly of the electrolyte. Because of quantum tunneling the parts know how to reassemble and give current back.
Have you tried potassium hydroxide with zinc oxide electrolyte with this cell?
Yes,.... but I make way toooo concentrated KOH (my bad). And when I put the aluminium foil into the cell,.... I get the volcano. So around 10% of KOH will be fine.
Awesome Video 👍 how long will it run would really like to know please thank you
It run for about 2- 3 hours on small piece of aluminium. KOH electrolyte will make better run.
Thanks for such awesome project, what is the charge cycle for such battery?
Charge cycle? Adding fresh aluminium and electrolyte
Is the aluminium only used when a load is applied? Or does the aluminium disolve over time because of internal resistance?
It will desolve due to the alkaline electrolyte attack on Aluminum
You can leave the aluminum there, if you want an "emergency battery" you are supposed to just drop in the liquid electrolyte and start using the battery.
@@ezequieladrianminniti6252 thx
Like @nicamarvin already said,.... the electrolyte will spontaneously react with aluminium, especially in KOH electrolyte. The reaction in NaCl electrolyte is much slower and the aluminium will protected himself with oxide layer. For that reason you need to add the electrolyte and aluminium when you will use the battery
Just wondering about the performance: power output and capacity? I'm guessing they are not huge.
brilliant work. what was your output?
1.2V and around 620 mA,.... but the current depends on the amount of aluminium.
@@cayrex That's a really usable amount of power! Can't wait to make one of these.
how long does it run for
2 to 3 hours on small piece of aluminium
Please make LTO lithium batteries What are the required materials? Please download a video about this battery and how it works
Something I don't understand. If you close the lid how is the air supposed to get into the air battery.
The cell will be fine with less that 1mm hole. And also the cell is not airtight
👍👌
Nice cell, would be good if it could use scrap drink cans rather than Al foil.
You can put any source of aluminium
@@cayrex I realise that, but you have to buy aluminium foil whereas empty drinks cans are already waste material and I was thinking of a cell specifically designed to operate on waste aluminium cans.
Great work!
However an electrically rechargeable al air battery would be a lot more practical. You could experiment with that too.
Correct! The Al-air batteries would be better if they can be rechargeable by electricity.
@@cayrex That is simply not going to happen!
@@idjlesand for this reason I said "would be" better if this would be posible.
@@idjlesSorry for my English😅
You mean Al-ion not Al-air
magnesium-air fuel cell, with diy magnesium recharge with MgO + H2 -> Mg+H2O
I have a challenge. I want to use a 20 l plastic bucket and make a battery inside it. You who have a lot of experience can recommend me some material that can be obtained. With about 10 buckets put in series, move an electric car. It's just for testing. I don't know whether to make an aluminum air. Can you recommend any of your videos to follow but on this scale?
So, you want to run a electric car on aluminium air batteries? Sorry I dont have any videos about that,... jet. For that case is needed to re-design the cell.
@@cayrexi mean if you can tell me based on your experience what kind of method I could use to make a battery of that size. Could you recommend me something? I saw videos of people using a 20 liter bucket with charcoal and copper electrodes but from your experience I am asking you if you think it is possible. In the end, who would make the expense would be me. thanks for answering.
Is this battery recharge able ?
Yes,... mechanically. You change the fuel (aluminium) and electrolyte
As-in can you use a solar panel to recharge the cell? No, it's not that kind of cell, but you can go to the kitchen and get the foil for your turkey and some salt from the table. All you need is something that makes Aluminium and salt from solar process 😁
Rejuzybuj aluminjum er bettery
Nice, simple architecture and of course very accessible for nearly anyone to DIY their own replica at home. A question if / when you have time to respond...with the air cathode buried within the case, do you think there's any risk of the air cathode in this configuration being starved of oxygen ? Also, and on a different topic altogether...but requesting at some point when you're perhaps trying to figure out what new content to create --> a build demo on your conductive HDPE...I've personally been unable to melt HDPE into a workable enough liquid form to just blend in the conductive materials and then solidify. I've done a few trials myself using a double-sided heater with an hdpe coupon coated with graphite / carbon on both sides which results in the conductive material being concentrated near the surface but so far I've been unable to promote a more fully blended / homogenous material. I'm still experimenting with an ldpe matrix around the conductive material and creating more of a conductive film as well as various methods with hdpe melting / creation of a composite make up but just curious if you're able to share your recipe for conductive HDPE, it would be greatly appreciated. And of course, thanks very much for your continued excellent content !
Hello. Thank you! About the air cathode that being starved of oxygen,.... not really. And about HDPE is that I dont make my own HDPE,... I buy it. I make some conductive plastic from polystyrene,... but not from HDPE.
@@cayrex Thanks for your time & thoughtful reply. Appreciate your continually insightful content. 👍
Please redesign it because the design is morronically clunky. In that volume you could pack definitely more cells in it to make it actually usable for daily use😂
Oh,.... if I want to make more practical I will go with much more different form. That was shown as diy project which many people can make out from basic materials. Because not all people have cnc, 3d printers, etc to make a fancy cells.
Well done for insulting a guy who is demonstrating something practical. Where's your morronic contribution?
