摘要： A gel electrolyte, a preparing method thereof, a gel electrolyte battery and a preparing method thereof are provided. The gel electrolyte comprises a non-aqueous solvent and a gel constituent, wherein the non-aqueous solvent comprises lithium salt, and the gel constituent comprises polyethylene glycol compounds with unsaturated double bonds, ester monomers with unsaturated double bonds, silane coupling agents and thermal initiators. The preparing method of the gel electrolyte battery includes preparing non-aqueous solvent containing lithium salts; dividing the prepared non-aqueous solvent containing lithium salts into two parts; adding initiators to one part to obtain a gel electrolyte part A; adding monomers and coupling agents to the other part to obtain a gel electrolyte part B; mixing the gel electrolyte part A and the gel electrolyte part B to obtain a gel electrolyte; injecting the obtained gel electrolyte into a dried battery and allowing the battery standing for 16 to 24 hours so as to sufficiently distribute the gel electrolyte inside the battery, and finally in-situ thermally polymerizing the gel electrolyte.
