ABSTRACT:
graphite sheet or block anode material can be used for non-aqueous lithium secondary battery, which has the improved characteristics of battery charge-discharge, as well as a circuit substrate and a shield plate in which dopants should be intercalated. The graphite sheet or block can be made of graphitized polymer film or films and comprises: a) an electric conductive body having a surface, in which graphite crystals are oriented along the surface of the graphite sheet or block and b) interphase insertion potions uniformly distributed over the surface of the graphite sheet or block, in which graphite phases are built perpendicularly to the surface to permit dopant to be inserted into a gap between graphite phases.
