▎ 摘　　要

NOVELTY - A graphene lithium-ion battery electrolyte comprises lithium salt, non-aqueous organic solvent and additive containing 5-6.5 wt.%. alkyl amine hexamethyldisilazane, 0.5-3.5 wt.%. octamethylcyclotetrasiloxane, 4.5-8.5 wt.%. graphene and 0.3-5.3 wt.%. vitamin E. USE - Graphene lithium-ion battery electrolyte (claimed). ADVANTAGE - The electrolyte has increased voltage bearing performance and circulation performance. The separation of hydrogen is reduced at high temperature storage. The capacity maintaining rate and capacity recovery rate of battery electrolyte are high. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene lithium-ion battery electrolyte.
