Two polar polymers with different dielectric constants, poly(viny1idene fluoride) (PVDF) and poly (ethylene oxide) (PEO), were each blended with a chlorine-terminated poly(ethy1ene ether) (PEC) and one of the two salts, LiBF4 and LiCF3C02, to form PECplasticized polymer electrolytes. The room-temper
## Abstract The addition of small amounts of crown ethers was observed to enhance the conductivity of the system PEO~20~LiCF~3~SO~3~ (PEO: poly(ethylene oxide)). Optimum conductivity enhancement was observed for the system PEO~20~LiCF~3~SO~3~(crown ether)~0.003~ when 12‐crown‐4 and benzo‐12‐crown‐4
