Getting amps from small selfmade DIY Zinc Air cells, amazing !

Hi Stefan.

there are some chemical formula similar to what you are trying to achieve but the is no details on volatility.

Since KMNO4 is a strong oxidizer there is a chance that when the Acrylic starts to set it might self ignite due to the oxidized accelerating of the chemical reaction.

I have never made the formula you are trying to achieve so I would make a very small sample first, test it for impact ignition, self ignition, and fire ignition, spark ignition. just to play it safe.

KMNO4 and sugar will self ignite if handled improperly. KMNO4 & KOH & Sugar will self ignite whether handled or not. be very careful.

try to keep the solution well ventilated incase there is a gas reaction on top of any other reaction present.

Many thanks.

These were the tips I was looking for...
So I will only add small amounts of a
weak KMNO4 -water solution to the graphite-acrylic binder mix
and
also use a low concentration KOH solution as the electrolyte and will
do it all on my balcony first with small quantities only...
Many thanks for these valuable tips !

Regards, Stefan.

@Stefan
I hope this is of some help to you ,I copied and pasted some companies that are commercialising Zinc Air bateries. I know a few universities and large corporations are also working on this. I copied this from the Freenegy website where I suggest you go and have a look.

Zinc Air
ReVolt Technology - Rechargeable Zinc-air batteries have more than twice as much energy as conventional Li-ion batteries, they cost less to manufacture, are safer to use, and are environmentally friendly. They are suitable for consumer electronics - mobile phones, laptop computers, digital cameras, etc.
New rechargeable zinc-air batteries coming soon - A new breed of rechargeable zinc-air batteries by Swiss company, ReVolt, is soon to be available, and may replace lithium-ion batteries in cell phones, laptops and other consumer items. Lithium-ion batteries store only a third of the energy and cost around twice as much as the new batteries. (PhysOrg; Oct. 29, 2009)

PAC Zinc Air Fuel Cells - Power Air Corporation's Zinc Air Fuel Cell offers an alternative to batteries, generators, and hydrogen fuel cells, producing zero emission energy for portable, stationary, light mobility, and transportation applications. ZAFC technology is low cost with all the advantages of batteries and engines, without the disadvantages. (The Energy Blog; May 2, 2007)

eVionyx - development of an inexpensive, metal-air, Revolutionary Power Cell (RPCâ,,¢) technology capable of meeting all of the requirements of the ideal energy source.
Fuel Cells > Powerzinc Electric - Dynamic Quick-refuel Fuel Cells (DQFC) are high power, high energy, long-lasting, low cost and environment-friendly zinc-air fuel cells for electric vehicles. The company is developing an all-Electric passenger car with a range of 400 km and a fast refuel service platform.

Hi. I have registered in this forum looking for a independet prize for a real world-scale new idea for solvering the world energy demand...I have one of such kind of ideas, can you tell me how can I apply for the prize, please?. Thank you so much. Dr. Luis Juanicó, argentinean researcher in renewables.
