Abstract: Conventional lithium-ion batteries are facing challenges safety issues such as liquid electrolyte leakage and flammability.The high safety and energy density of lithium-ion batteries can be achieved by replacing liquid electrolytes with solid electrolytes.However, the traditional preparation method of solid electrolytes membrane has a complex preparation process and high energy consumption, which adds challenges to its practical application.The preparation of solid electrolytes membrane by solvent-free method has the advantages of energy saving and environment friendly, which saves the solvent drying and solvent recovery steps in the traditional preparation process.However, the application of this technology to prepare solid electrolytes membrane in the field of energy storage is still immature and needs further research and development.This review summarizes the research progress of solvent free preparation of polymer, inorganic and composite solid electrolytes membrane, expounds the challenges faced by solvent free preparation of solid electrolytes membrane in the commercialization process, and finally forecasts the practical application of this technology in all solid state batteries in the future.
