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

[@arabiccola]

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

[@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

[@MrElectron]

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.

👍verry good 👍thank's

[@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. 😁

[@MrElectron]

Thanks! Video about the same is coming tomorrow or the day after. Yes its easy to buy koh here.

[@raymondhintz5457]

Where do you get air battery if you use an electrolyte?

[@cosmefulanito5933]

This is not aluminium. Is galvanized steel

[@david2ljdavid2lj56]

Came to the comments to say that.

[@hegelee]

I was about to comment the same

[@smaxinfo]

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.

[@Rockworksbyashish]

Bro try to use pencil ✏️😅

[@Rockworksbyashish]

It's also available carbon must use 10hb😅 fevercassil

[@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. ❤

[@MiguelAlejandro1969]

Tienes un problema allí. El carbón debe estar separado del aluminio sólo unas micras con aislante y el aluminio debe ser mas grande y cubrir todo el carbón en su entorno. Así te aseguras mas corriente. Es fundamental igualar la supreficie de ambos electrodos y suinima separación. Ahí es donde fallan los maH de capacidad.

[@yankozlatanov]

The problem with this battery is the aluminium will be destroyed by the electrolyte very quickly no matter if you draw current or not. Probably you should remove the hydroxide electrolyte when the battery is in storage.

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.

This does not seem to be an Al Air battery, just a redox battery.

[@gsestream]

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.
