▎ 摘　　要

NOVELTY - The composite material is obtained from the raw materials containing graphite 1% to 40% and the hard carbon is 60%~99%. USE - Hard carbon/graphene composite material. ADVANTAGE - The hard carbon/graphene composite material has good conductivity, excellent mechanical property, higher power density and volume capacity. The service life of composite material is prolonged. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a hard carbon/graphite composite material preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a scanning electron microscope image of hard carbon/graphene composite material. (Drawing includes non-English language text)
