LeopoldS on 07 Nov 11any idea how this works - who wants to have a closer look at it?

dejanpetkow on 08 Nov 11Water is used for keeping the graphene stacks separate. Without water or some other separation method the different graphene stacks would just stick together and graphene would lose its nice properties (like a huge surface). So, water has nothing to do with energy but is just the material which keeps the graphene stacks at distance. The result is a gel. Still, energy needs to be stored in the gel.

LeopoldS on 09 Nov 11and the different graphene layers act as anodes and cathodes??
-
dejanpetkow on 09 Nov 11Layer orientation in a gel is random. Additionally to that, cathodes and anodes are about charge seperation. Graphene layers are (as far as I understand) supposed to provide huge surfaces to which something, maybe a charge, can be attached. So do we need ions and electrons? Probably not. Probably just electrons which can travel easily through the gel. I guess the whole gel (and all layers inside) would be nagtively charged, making the gel blob a fluid cathode. But again, it's just a guess.

LeopoldS on 10 Nov 11Wouldn't it be worth having a closer look?

LeopoldS on 12 Nov 11it's still not clear to me how to get electricity in and out of this thing?
