Abstract

We have investigated both AC dielectric permittivity and ionic conductivity of hybrid composite solid polymer electrolyte (CSPE) films ( 100 ?m) comprised of sub-micron sized aluminum substituted cubic Li7La3Zr2O12 (LLZO) particles dispersed in polyethylene oxide-LiClO4 (PEO-LiClO4) matrix with [EO]:[Li] = 15:1. Homogeneous CSPE films with 50 wt% LLZO (PEO-LLZO-LiClO4) exhibit good flexibility and mechanical robustness up to 120
