Intercalated graphite carries a resting voltage without giving a charge.

Smoky2, I can only guess that your suggestion to use graphite is to point out something I'm overlooking.

It was for Jimboot , to eliminate galvanism as a possible explanation.
it is standard battery practice to use inert electrodes.
this also prevents corrosion and extends the lifetime of the cell.


You can connect Al or Cu or any suitable conductor to a graphite rod
and not worry about erroneous readings.


Analog meters don't usually cause the same problem that the DMM's do.
Because internally they are built to respond to the circuit,
Where as a DMM alters the circuit then analyzes the results.


Also DMM's can be susceptible to static charges and be inaccurate at times.
(sometimes shorting the terminals or removing the battery can 'fix them')




On the uneven paper electrode surface:: the paper towel might not be the best way to go.
You may need coffee filter or something that will stay flat

Thanks for the info, I have a roll of celgard 2400 seperator material on order. What I need badly is some ideas for a non aqueous electrolyte that would be suitable for aluminum ion battery.

I will repeat the test tomorrow using filter as you suggested. I'm on night shift so I'm getting a little cross eyed from no sleep.

At 65% humidity 1.125 at 60% 1.140 . Btw this started at 300mv . I surprised it's risen over time. My analogue meter is busted but that will be a good test.

Also these are screen shots I took on the 21st. I'm using the house ground which is adding by the looks of it a harmonic set of spikes. The zoom is of the final spike in the sequence.[/size]
