▎ 摘　　要

NOVELTY - Preparing graphene by mechanical stripping, comprises (1) dispersing the graphite raw material in foaming agent aqueous solution to obtain graphite pre-dispersion liquid; and (2) grinding the graphite pre-dispersion liquid, washing with water, centrifuging and grading to obtain the graphene; where the foaming agent aqueous solution comprises sodium alpha-alkenyl sulfonate, fatty alcohol polyoxyethylene ether sodium sulfate, coconut oil diethanolamide, polyethylene glycol and water. USE - The method is useful for preparing graphene by mechanical stripping. ADVANTAGE - The graphene is useful in preparation of catalyst or battery active materials (claimed).
