▎ 摘　　要

NOVELTY - Graphene electrolyte comprises an electrolyte salt lithium, non-aqueous organic solvent and additive, where the additive is terephthalic acid ester and/or trimesic acid ester; the conductive agent is prepared by propylene carbonate and graphene, flame retardant based on the total mass of the electrolyte, the mass ratio of additive is 0.5-5%, conductive agent is 5-10%, and flame retardant is 0.1-2%. USE - The graphene electrolyte is useful for lithium-ion batteries. ADVANTAGE - The graphene electrolyte reduces the attenuation speed of the battery capacity, increases the battery internal resistance, and improves the lithium and compatibility of the ion battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of graphene electrolyte for lithium ion battery.
