Intercalated graphite carries a resting voltage without giving a charge.

Made a new cell of ground up material. Wrapped in tissue a few drops of salt water. Then clampep. 800mv over the 3k resistor same waveform but the scope voltage is 10x whereas the dmm is still 1.1? Wtf also the earth spikes have phase shifted

In all my battery experiments at home I use graphite cathode and aluminum anode. Depending on the electrolyte and its strength will effect its performance. The highest voltage I was able to get was 2.8 volts. This was by replicating a YouTuber named Cayrex2. The video I believe was "bi-functional hydrogel aluminum battery".

When you wrap the tin foil do you put shiny or dull side facing out. If you put shiny side facing out does it start to dull over time. Or should I say faster than it normally would.

Smokys comments have forced me to rethink everything I have done up too this point.

Kaj,


Important thing to know about aluminum foil
(or any pressed oxidizing metal foil /thin sheet)


The machines that do this run dual-layers of material
against each other then press them.
the shiny side was facing the roller and has a very thick oxide layer
the dull side was al-al through the press and the oxide layer is very thin


Always put the dull side in the battery. This surface can make a much
better contact with the electrolyte.








Jim,
you see from that circuit now what I was talking about?
The 1MOhm resistor in the DMM can feed that V back the other way
I'm pretty sure the 1V is the drop from 5v to 4v internally
the resistors are set up for multiple pathways and the IC can bleed
so while you are measuring outside, the inside sends the V through
the lead loop, and picks it up as a measurement.


With the analog meter it has to actually BE there to move the needle.


The scope shot is interesting.
Seems like it is able to pick up the signals better when it's smaller pieces?
I know this isn't about earth currents, but your "antenna" got an upgrade
