▎ 摘　　要

NOVELTY - A laminated composite electrolyte with interface optimization function comprises organic electrolyte, inorganic electrolyte and silane coupling agent containing acrylamide groups. USE - Laminated composite electrolyte with interface optimization function for solid state lithium-ion battery (claimed). ADVANTAGE - The laminated composite electrolyte with interface optimization function can exert the function of coupling agent organic/inorganic interface, can utilize multiple hydrogen bond of acrylamide group, can improve the environment of lithium-ion, improve the conductivity of the electrolyte, and has strong affinity, can control the lithium-ion diffusion behavior on the surface of the lithium negative electrode deposition/dissolution of the uniform lithium, and further improve the stability of the electrode/electrolyte interface. The method is simple and easy, inexpensive, and is suitable for large-scale production. The chemical effect combined with flexible physical characteristics of organic component of two sides of electrolyte can effectively improve the rigid interface problem of the solid state battery system. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a solid state lithium battery, which comprises positive electrode sheet, negative electrode sheet and the laminated composite electrolyte having interface optimization function.
