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

[MW383]

Read the following Zinc Air Battery patents. Should aid construction efforts for those building these things.

I can personally attest to the capabilities of this battery chemistry in regards to power aspects.

Hi All,
as I look on the graphics of:

http://www.revolttechnology.com/res/photo/-11.battery_layers.jpg

it might be, that they put the KOH eletrolyte just into a gel based
solution, so the electrolyte is just not a liquid , but a gel.

You can get cheap gel salts, that bind water and other liquids from
diapers via Superabsorbers ( PolyAcryl-Salts)

See here:

Translate it with Google.

Via the gel based electrolyte it might be easier to recharge the cell
without the KOH destroying the cell.

Hi All,
today I bought Pottassium Permanganat
(in German language Kaliumpermanganat KMnO4)
and I want to mix this with lampblack (some kind of conductive graphite-carbon) and an acrylic binder
to produce one eletrode of the battery.

Do you think this will be dangerous ?
As Pottassium Permanganat (KMnO4) is a very high oxidizer and can selfignite with some
other chemicals like Glycerin (glycerol)
how should I prepare this without blowing myself up ?

Maybe it is best first to solute the Pottassium Permanganat into water and then
add wet lampblack and then add the acrylic binder ?

Will this get hot ?

And then let it dry ?
Could I heat it up a bit to get it faster to dry or will this explode then ?

I want to use this as one electrode and use KOH or K2CO3 in water as the electrolyte
and Alufoil or a Zincplate as the other electrode for this airbattery...

So will I blow myself up, if I will try this or what other precautions should I take ?
I don´t want to get my fingers ripped away from an explosion.

I know how dangerours for instance Acetone-peroxid is,
with which I played in my younger years and that exploded
already by hit with a hammer !


Please let me know.

Many thanks.

Regards, Stefan.

one drop at a time, test it for volatility.
