Glass-polymer composite electrolytes of high lithium ion conducting oxysulfide glass and the comb-shaped poly(oxyethylene) polymer (TEC-19) were prepared. The conductivity of the composite with 2 vol% TEC-19 doped with LiClO4 was 1 x 10(-3) at 100 degreesC and 3 x 10(-5) S cm(-1) at 30 degreesC. The composite exhibited a 4 V stable potential window versus Li+/Li.
