摘要: Composite polymer electrolyte films consisting of poly (acrylonitrile-co-methyl methacrylate)(P (AN-co-MMA)), EC–PC, LiClO4 salts, and also silica particles have been prepared, and their electrochemical properties were studied. A maximum in the ion conductivity was found for the plasticized polymer electrolyte containing 10 wt% silica with EC–PC and was 1.7× 10− 4 S/cm at− 15° C and 1.9× 10− 3 S/cm at 25° C. The reduction in Tg of the plasticizer-rich phase in the composite polymer electrolytes due to the interaction …
