▎ 摘　　要

NOVELTY - A 3D porous carbon material producing method involves distributing pi - pi precipitated ferromanganese oxide nanoparticles on graphene surface at high density. Carbon nanotube is grown perpendicular to the graphene surface by chemistry vapor deposition method to obtain finished product. USE - Method for producing porous carbon material that is utilized in lithium-ion battery (claimed). ADVANTAGE - The method enables producing the porous carbon material with improved storage capacity of carbon nanotube and graphene, overcoming agglomeration problems of graphene and carbon nanotube during drying process, increasing electronic conductivity of carbon material and improving transfer ability and porous property of battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a lithium-ion battery comprising a cathode material and 3D porous carbon material.
