▎ 摘　　要

NOVELTY - A modified porous graphene is prepared by subjecting porous graphene to modification with surface treatment and organolithium compound. USE - Modified porous graphene used in preparing modified porous graphene cathode electrode sheet for batteries. ADVANTAGE - The modified porous graphene produces modified porous graphene cathode electrode sheet which has high coulomb efficiency and large magnification, by controlling specific surface area, particle size, pore size distribution and surface functional group content of porous graphene. The continuous batch preparation can also be achieved by controlling thickness and density. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of modified porous graphene cathode electrode sheet using modified porous graphene.
