you can use sausage casings as a separator

No problem

Nice video. I just lacked carbon-magnesium. 👍

Espectacular todos tus vídeos.. Felicidades te animo a que sigas con el mismo ímpetu. Muy interesante lo del doble electrolito.. Has obtenido un voltage interesante me gustaría saber cual es su corriente... Saludos cordiales.

Well. Yes. Old.good.Al.....i.like.it.

Yes, the current depends mainly on the type of active material. Some material will give you better current that others.

I wonder what the shelf life is on that battery.

@cayrex 14 дней назад

The shelf life of the aluminium battery without corrosion inhibitor will be short. If the aluminium is mechanically removed then the shelf life much more extended. Or if you use a zinc version of that battery then the shelf life will be also better.

I didn't know what "dual electrolyte" meant. Now I've learned it's acid/alkaline. Any combination possible. Now I hear an aluminum/iron combo. What??? That makes thermite!!! Just more click bait I found on RU-vid. You're awesome. Thanks.

So, an aluminum air battery could be modified by using Nacl and "charged" converting NaCl into its constituent chemicals. Two problems: hcl and chlorine gas. They could be engineered to mitigate but always present and a risk. Thanks again.

I've taken my jar lid aluminum air battery and used saltwater. It recharges again and again. Used coffee filter, wax paper and pva and heat pressed it. Works a little longer. I had a good battery day. Thanks

Nice content! How much current can a single cell give? I'm trying to make this cell for a project and I'm worried about current. A single Li-ion cell gives around 3A as the max discharge current. Also, the current depends directly on the surface area? Finally, could the graphite plate be replaced with a stainless steel mesh? Does it affect the oxigen difusion through the cell? Hope u can help me with those questions. I follow ur content and its really helpful as well as interesting!

@cayrex 13 дней назад

The current will depending on the amount, type and surface area of the active material. Yes you can use SS mesh,... but this will only effect the voltage a little bit.

oui, c'est sympa les air batteries... et le charbon actif dopé à l'azote dont tu nous avait parlé ? hihi! ;-)

@Tikun-Israel5784 14 дней назад

Non Rechargeable, correct?

@cayrex 14 дней назад

Correct. Aluminium version is non rechargeable. The zinc version is rechargeable

have you ever submerged crushed aluminium foil into concentrated koh water. it goes hydrogen poof instantly. koh is not actually suitable for high surface area aluminium-air battery. koh might be fine for thick block plate aluminium-air battery. try baking soda instead. for single electrolyte aluminium air battery. baking soda is dirt cheap, if using bags of soda blasting media. how about baking soda vinegar dual electrolyte cell. yep vinegar with baking soda will produce tons of co2 if the are mixed. a ceramic tile would work also for the membrane. also the baking soda will remove the oxidation layer from the aluminium. ceramic membrane is just a porous glass fiber separator. how about a gravity cell, where top electrolyte is koh and bottom one is h2so4. well requires electrolytes that dont react acid-base. sometimes is not worth the hassle to have two electrolytes when they make the flooded cell structure way more complex.

Uuuuu for sure,... I run hydrogen fuel cells with aluminium. Yes baking soda can work and can be used in the cell, but can also limit the performance of the cell (comperisong to the KOH cell). But In most cases when is used KOH or NaOH electrolyte some alloys of aluminium and tin or others are used for the anode. In the end,.... you have tons of combination which can be used as a cell.
