▎ 摘　　要

NOVELTY - Graphene powder is obtained by spraying and stripping graphite through a supercritical fluid slit. USE - Graphene powder for graphene conductive paste for lithium ion batteries (all claimed). ADVANTAGE - The graphene powder ensures low cost, mild conditions, no pollution and easy control, and is more suitable for industrial promotion and application. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a graphene conductive paste, which comprises 2-4 pts. wt. graphene powder, 0.5-1 pts. wt. binder and 95-97.5 pts. wt. solvent; and (2) a method for preparing a graphene conductive paste, which involves immersing the graphite in the supercritical fluid under the condition of airtight pressure, and mixing to obtain the supercritical state mixed liquid, pressurizing the supercritical state mixed liquid, slit spraying and peeling to obtain graphene powder, mixing graphene powder, binder and solvent to obtain the graphene conductive paste.
