▎ 摘　　要

NOVELTY - The carbon system cathode material is composed of 90-95 wt.% of carbon cathode, 1-5 wt.% of binder pitch, and 1-5 wt.% of graphene. The contact of the edge plate is exposed to the electrolyte and the base plane is aligned in the vertical direction to the carbon cathode surface. USE - Carbon system cathode material. ADVANTAGE - The graphite is coated on the carbon cathode surface so that the surface conductivity of the cathode material can be improved. The used amount of the conductive material can be reduced in the electrode metallization so that the charging/discharging efficiency can be increased with high conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for carbon system cathode material manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the carbon system cathode material.
