▎ 摘  要

NOVELTY - Preparation of porous graphene, involves reacting graphene and hydrogen peroxide at weight ratio of 1:5-1:50 along with stirring at 80-120 degrees C for 3-6 hours, separating the graphene oxide, and reducing the graphene oxide with a reducing agent to obtain a porous graphene. USE - Preparation of porous graphene used as electrode material in supercapacitor and rechargeable ion battery such as lithium ion battery. (all claimed). ADVANTAGE - The graphene is obtained with nanopore structure, and the pores are even. The battery is obtained with improved energy density.
