Graphite-Paper - Aluminium-Foil galvanic cell with 1.7 to 1.92 Volts

Yes, that is also a good idea to use it as
just an energy generator and charge up a battery via a joule
thief or simular pulsing circuit.

Also please have a look at what Henrique Sousa
is doing.
He is also building great ALuminium air cells:

Have a look at his blog:

Lithium batteries are not good for the environment !
Aluminium would be better !

I hope you aren't cooking food on that stove, after making those experiments.

Joke aside, so you made a primary battery, what's the big deal?

People have been doing this 100 years ago as it has been a main source of portable (and other) EMF, beside the mains (DC and AC). Actually, there had been many more primary battery designs, some better than this one that produce much more current.

As a side note, you might want to short-circuit your cell for 12-24hrs after it's made, to bring it to the full current potential.

If you want a higher current cell, look up the Gethins and/or the Hussey bluestone cells. They give out around 1V but 1-5A output, in standard sizes.

Just my 2c.

Hi Plengo,
do you mean this paper ?

Or please post links to the other cell you mentioned.

Well, I am not claiming to produce anything very new,
but I just want to find a cheap solution how to do
an emergency battery at home or a cheap battery
selfmade battery, that can be used with Joule Thief circuits
for lighting purposes and uses only very cheap resources
like a bit of alufoil from the supermarket and can power
pretty long your LEDs.

Also it can be tested, if it will
be reachargeable when using superabsorbers
for the electrolyte and use reverse current to charge up
the cell.
There are still many things to try out to enhance the
functions of these cells and their power output.

Regards, Stefan.
