Graphite – Wikipedia
The acoustic and thermal properties of graphite are highly anisotropic, since phonons propagate quickly along the tightly bound planes, but are slower to travel from one plane to another. Graphite’s high thermal stability and electrical and thermal conductivity facilitate its widespread use as electrodes and refractories in high temperature material processing applications.

Electrochemical and thermal properties of graphite
To evaluate the electrochemical properties of graphite electrodes, a slurry was prepared by mixing 97 wt.% graphite as an active material with 3 wt.% polyvinylidene fluoride (PVdF) binder dissolved in anhydrous N-methyl-2-pyrrolidinone (NMP). The resulting slurry was cast on copper foil and the composite electrode was dried in a convection oven
