SOLID-LIQUID HYBRID ELECTROLYTE MEMBRANE AND METHOD FOR MANUFACTURING THE SAME

The present disclosure relates to a method for manufacturing a solid-liquid hybrid electrolyte membrane, including the steps of: (S1) preparing a dispersion containing a plurality of polymer particles dispersed in a liquid electrolyte and a volatile organic solvent; (S2) applying the dispersion onto a substrate, followed by drying, to form a porous structure; and (S3) pressurizing the porous structure to obtain a solid-liquid hybrid electrolyte membrane, wherein the solid polymer particles in the porous structure are packed, while being in contact with one another, the porous structure includes a pore structure formed among the solid polymer particles, the liquid electrolyte surrounds the inside of the pores of the porous structure, the portions in which the solid polymer particles are in surface contact with one another, or the surfaces of the solid polymer particles, the content of the liquid electrolyte is 1-20 wt% based on the total weight of the solid-liquid hybrid electrolyte membrane, and the organic solvent has higher volatility as compared to the liquid electrolyte.
