​Generally, rubber is insulated. If it needs to be conductive, then conductive material needs to be added. Graphite powder has excellent conductivity and lubricating release properties. Processing graphite into graphite powder has excellent lubrication and conductivity. The higher the purity of the graphite powder, the better the conductivity.

The advent of graphene broke the graphene that the scientific community guessed at the time could not exist alone, but needed Graphite exists as a carrier,Graphene is used as a negative electrode material to exhibit superior effects.
