▎ 摘　　要

NOVELTY - A graphene material comprises porous graphene sheet and halide particle in porous graphene sheet layer. The halide particle is present as a single layer uniformly paved on the graphene sheet. USE - Graphene material for electrode material preparation for battery. ADVANTAGE - The material uses inexpensive raw materials and can be manufactured using simple equipment at reduced cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene material comprising taking halide plugging layer porous graphene material for ultrasonic peeling in the presence of solvent.
