▎ 摘　　要

NOVELTY - Coating material comprises 0.1-30 wt.% conductive agent, 0.1-30 wt.% binder, 0.01-30wt.% coupling agent, and solvent (remaining amount). USE - Coating material for laminated electrolyte and solid battery. ADVANTAGE - The coating material effectively solves the problem that the inorganic electrolyte film and the organic electrolyte membrane are bad, the interface is deformed to generate gap, the problem of bad bonding between organic matter and inorganic substance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: a preparation method of laminated electrolyte; anda solid state battery. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of the solid-state battery of a coating material. 1Sequentially Anode 2Electrolyte layer 3Cathode 21Organic electrolyte membrane 22Inorganic electrolyte membrane 23Mixed glue solution
