Intercalated graphite carries a resting voltage without giving a charge.

hi all I'd mad some intercalated graphite recently using fecl3 and some plant material. I used Robert Murray smith method of soaking in fecl3 then into the kiln slowly ramped up to 750c . The device on my bench measures just over a volt and is dry. Not a chemical reaction. Can post scope shots and videos if anyone wants to take a look. It does not seem like normal behavior though. MERRY CHRISTMAS!

Hook a bunch of them in series and parallel
See what happens


By the way, is your ground reference the earth?
Or is your scope isolated?


During the Cold War ionic carbon was thought to be a
potential source of a room temperature superconductor.
Many governments enlisted the scientists of the world to
try and make one.
They are still trying today......

I've tried both more interesting results with the house ground https://youtu.be/mfo_ITGSjh8 you may recognise the material given your handle. Check your pm at our.

Here's a quick and dirty conductivity test https://www.youtube.com/watch?v=mGU5Aw7hKKE

If you have your meter connected between anode and cathode you are seeing galvanic voltage. You won't be able to discharge it like a capacitor. I am also working on a rechargeable aluminum ion battery. I've only been at it a few weeks so I've still much to learn. Looking forward to seeing your further progress. Ps: The oxide layer that forms on aluminum is a killer. Saltwater will not readily strip it away.
