[@conceptcreation]

yes I agree with you but that doesn't prevent it from not being air or O2 so you contradict the title of your video. I know air capacitors very well because they were adjustable but air batteries, unless you call them violins because you will have to blow into them to be energetic

[@conceptcreation]

Is your battery rechargeable???

[@arabiccola]

I loved how excited he got when the battery worked, we need more of that genuine excitement for science and expérimentation 🎉

[@shahramarya6417]

Your work was great, we are waiting for the next video🇮🇷🇮🇳

[@MrElectron]

Episode 3 video 👉 kzbin.info/www/bejne/iH6vmHiDoZilhdE Nice to see you all participating. The anode metal i used is aluminum. It looks like that because i started working on air batteries around 3 months back, and that's when i poured Koh on it because of which it lost its shine. Yes, i also tried aluminum heat sinks as the electrodes, and i got the same result as I am showing here. Same for the aluminum line cables as electrodes. For me, Vmax was 1.7v per cell in one of my experiments under some very specific conditions. It's not shown in the video.

[@markcampbell9198]

[@HetemHassan-i1d]

Would you possibly know how does Naoh compare to koh for electrolyte in these cells? I know it's simple enough to convert one to the other but just wondering for simplicity's sake. I can find Al and graphite on the streets picking up scrap all day and can buy a lb of Naoh at Wally world for ~6$ just koh is slightly less accessible

[@HetemHassan-i1d]

Btw meant to say ty for such a great concise video this would make a great cell for an emergency situation with the availability of these components. Keep up the good work.

[@shhall1]

OMG! Thanks for pointing out what those little carbon things were with the picture. I just had a corded drill burn out on me so I dissected it and saw those exact things you pictured and now I know what they are, so I know what I can use them for. You Rock!

[@MrElectron]

😊

[@partciudgam8478]

that is galvanized steel, (then it will be a zinc-air battery) aluminium looks like the heatsinks on your LEDs, aluminium air gives out about 2 volts per cell, and tends to fall quickly as hidroxides block the cell.

[@danjelbm]

its certainly Zn galvanized steel, and I guess that battery lasted for 20 minutes. its like 12um Zn max on it, and it goes so fast

How can I prepare a liquid electrolyte to dissolve the sulfate in the gel battery electrolyte? Can you help me?

[@christopherleubner6633]

Ingredient for cathode Aluminum, ingredients for the anode, activated carbon, manganese dioxide ,iron oxide, and graphite. Anode current collector can be either copper foil or steel.separator can be paper towel or cloth. Outer wrap should be made of something oxygen permeable but water tight like tyvek. Electrolyte can be either potassium aluminum sulfate or potassium hydroxide. The alum based version will need some current to kick start the reaction but will store for a long time, the potassium or sodium hydroxide version will self start but is use it or lose it. This version can be made dry to be activated by water at a later date. ❤

[@dav1dbone]

You made a good DIY battery, I am confused as to how the carbon brushes are working as air cathode? Also it would be better if there was a non caustic electrolyte as we know much anode material is lost due to reacting and releasing H2. Can you easily buy Koh powder in a tub in your local shop, we don't have it nearby? Thanks 👍

[@neepsmcfly4176]

I'm no chemist but as I understand it, you'll have to mix the pot hydrochloride powder w distilled water which, after double checking my math, would make the hydroxide. Dunno if you can get it premixed. I do know someone who's in the know, tho. Starts w an A & ends w a zon. Tell em Troy sent ya. 😁

[@thexaviousdoesthings568]

This is really great, aluminum-air batteries look incredibly promising, i appreciate you providing excellent information on it. I have a question though, are the three carbon brushes per cell necessary? What would be the effect of less? Are you mostly just trying to get more surface area? I can't want to test this chemistry myself, but i'm tinkering with zinc-iodine batteries right now, i dont want to get too far ahead of myself!

[@MrElectron]

I'm glad you liked it! Yes, it's the surface area. All the best with your zinc iodine battery research. I, too, will look into them.

Возможно есть материал или вещество которое может поглощать выделяемый газ еще до того как он поднимется на поверхность. Есть такое вещество? Например рядом с алюминием в электролит поместить его для частичного поглощения выделяемого газа. Ведь это касается безопасности, это важно.

[@MrElectron]

Or one can find a method for reducing the hydrogen emission by modifying the electrolyte.

[@neepsmcfly4176]

Yeah, my initial reaction was to laugh but, hell, you're on to something there!

[@neepsmcfly4176]

​@@MrElectron less h release would be Byproduct of lower output, would it not?

[@joseferraz-sq3tm]

É o gás que reduz a capacidade da célula produzir intensidade. As bolhas ao formarem-se afastam o electrólito das paredes do eletrodo de alumínio reduzindo a superfície de contacto/ área activa. Há substâncias que absorvem o hidrogénio. Nas pilhas zinco-carvão é o dióxido de manganês que é o despolarizador de forma a impedir que o hidrogénio isole o eléctrodo. Aumentar a área dos eléctrodos aumenta a capacidade e a intensidade.

[@hikewomeat]

Если вместо раствора щелочи КОН использовать окислитель, например, хлорку, содержащую гипохлорит, то выделения водорода не будет происходить. Напряжение так же будет выше, примерно 2,2 В. Такие элементы используются в реальности. Для эффективной работы и большого выхода тока важна развитая поверхность алюминия и небольшое расстояние между электродами.

try carbon fiber cloth instead, much simpler to use, resistance of graphite cloth is very low, close to zero, same as those brush carbon blocks. baking soda works even better, for aluminium-air and is non-toxic. also baking soda reacts less with the aluminium, mostly removing the aluminium oxide only, very different to potassium hydroxide, which actively produces hydrogen from the aluminium.
