DIY Reusable Aluminium air Battery 

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

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.

What in your experience is the best all round battery.not to expensive not to dangerous good capacity charge .a diy battery

can you tell about the output capacity of this cell. i mean voltage and currunt and time. MAH

Very nice, I like the fact that you can change the anode very easily, as well as using just regular foil.👍🏼🙂

Awesome Video 👍 how long will it run would really like to know please thank you

Very nice! Simple to build but very effective, I will try this out myself for sure 👍✌

Awesome! Does the reacted Aluminium stay in solution or does it kristallise at the bottom? Thanks for sharing!

how long does it run for

very interesting!

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 ?

magnesium-air fuel cell, with diy magnesium recharge with MgO + H2 -> Mg+H2O

Freakin awesome dude!!

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!

Simple and easy

Really nice battery! I've got to make one myself. How how did you activate the carbon felt?

Rejuzybuj aluminjum er bettery

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.

BIG BROTHER THANK YOU FOR LIFE SAVING TECHNOLOGY FOR US.. THANK YOU FOR YOUR TIME 👍👍👍👍👍

This idea will be useful for further modifications and to make it vaiable for day to day use. Really awesome 🙏

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.

Fun, educational, inspiring and useful proof of concept.

Of those you've already done, would this be the one with the highest current output?

That's pretty incredible honestly

brilliant work. what was your output?

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

Have you tried potassium hydroxide with zinc oxide electrolyte with this cell?

Excellent video. What are you using for the filter paper separator?

👍👌

very interesting! thx!

Is this battery recharge able ?

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?

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?

You're gong crazy with that 3D printer! 😊

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

Thanks for such awesome project, what is the charge cycle for such battery?

Nice cell, would be good if it could use scrap drink cans rather than Al foil.

Great work! However an electrically rechargeable al air battery would be a lot more practical. You could experiment with that too.

Is the aluminium only used when a load is applied? Or does the aluminium disolve over time because of internal resistance?

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😂

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 !
