摘要:
Provided is a method of producing a nanoparticle-filled phase inversion polymer electrolyte. The method includes mixing a nanoparticle inorganic filler and a polymer with a solvent to obtain a slurry; casting the obtained slurry to form a membrane; obtaining an inorganic nanoparticle-filled porous polymer membrane by developing internal pores in the cast membrane using a phase inversion method; and impregnating the inorganic nanoparticle-filled porous polymer membrane with an electrolytic solution. The polymer electrolyte produced using the method can be used in a small lithium secondary battery having a high capacity, thereby providing an excellent battery property.
