The EOET-LiClO_4 electrolytes exhibit not only high ionic conductivity, but also good mechanical strengthand toughness. The EOET 3400--25--LiClO_4 complex possesses the highest conductivity (4. 65×10^(-5)s·cm^(-1) at room temperature when the ratio [Li^+]/[EO] equals 1/16. The structures of these electrolytes were examined with FTIR analysis, X-ray diffractionand DSC thermograms, and the results of high ionic conductivity of the segmented copolymerswere discussed.展开更多
