DIY Multi metal air Battery - Aluminium air "flow" Battery 

bon travail, c'est intéressant pour le principe du flow... mais: ça reste un fuel cell qui, comme les batteries primaires ne se recharge pas: du gâchis de matière et de la pollution à mon avis😪 les accumulateurs, supercapacitors, redox flow, ... ont de l’intérêt car rechargeable. methanol /ethanol hydrogène fuel cell pourquoi pas, c'est accessible et renouvelable... pas l'aluminium ou les terres rares... en tout cas ce que vous faites est genial😀😉, ça aide beaucoup de monde sur l'autonomie énergétique merci

Very nice concept that enables the extended use of a primary cell and, instead of a traditional primary cell, keeps re-using the basic battery infrastructure and only swaps out the consummables (aluminum anode and electrolyte). I don't know the full energy and financial accounting of this architecture but seems like scaling up would benefit those equations....although I do still think while it "looks" inexpensive to just use something so seemingly cheap as household aluminum foil, the larger equation of the energy and financial cost to produce aluminum would still keep this as an energy source more expensive than the burning of hydrocarbons....however, pure financial expense is not always one's objective and I can see a lot of useful applications for this.

I was thinking of something similar where you threw aluminium cans in although the paint/coatings/continuity on the cans would cause problems. Difficult but nice if you ever get it to work.

Thank you very much for the useful videos. Is it possible to show the preparation of sodium batteries?

Great iteration man

Very clear explanation. I will try this some time. Here is an idea. Not sure if it would work at all but here goes. I have tried a few things that produce voltage but negligible current this could be another one of those. If you have two granular (sand like) materials with different electronegativity (aluminum vs lead) as well as a buffer sand and you had them mixed in some electrolyte solution (just wet) or maybe dry. Imagine there are collector plates on the top and bottom of the mix. Is there any chance you could generate voltage with usable current as the particles moved up or down (because of liquefaction) based on their density and difference in electronegativity? Just a thought. If it worked it would only produce when in a state of liquefaction and there would be no real consumption of material. Best start may be to have a layer of buffer sand covering each of the collectors. As the liquifaction begins the heavy particles would sink and the lighter ones with float making contact with their respective collectors. I could not find this idea explored anywhere so likely not viable. ChatGPT did not say it had no chance of working.

looks like putting a coin in the machine

Awesome 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻

Me párese un buena idea,, me gustaría ver cuantos volt. Produce y cuantos Amperios o miliamperios

i would like to see a all-liquid "refillable" fuel cell, for example use the reaction between bleach and hydrogen peroxide, separated by a proton exchange membrane. (similar to a hydrogen fuel cell) I'd try it myself but i dont have to tools or equipment to try it.

We now have mature vanadium battery products for household and commercial use

Do you have characterization values available? Discharge curve, Coulomb efficiency, energy efficiency, energy density, power density, etc?

Would it not be easier to have an open type of cell and physically lift the Al electrode from the electrolyte when not in use?
