The polymer electrolyte formed with poly(ethylene oxide), P(EO) and LiClO4 in the n = 8:1 ratio (n = [EO units]/[Li]) was exposed to γ-radiation at room temperature in aqueous solution, then dried and characterized using thermal and conductivity measurements. Its improved electrical and mechanical properties, in comparison with those of the non-irradiated material, suggest that cross-linked P(EO)8·LiClO4 can advantageously replace the usual polymer electrolyte of the same composition in electrochemical devices in the solid state.

Abstract
The polymer electrolyte formed with poly(ethylene oxide), P(EO) and LiClO4 in the n = 8:1 ratio (n = [EO units]/[Li]) was exposed to γ-radiation at room temperature in aqueous solution, then dried and characterized using thermal and conductivity measurements. Its improved electrical and mechanical properties, in comparison with those of the non-irradiated material, suggest that cross-linked P(EO)8·LiClO4 can advantageously replace the usual polymer electrolyte of the same composition in electrochemical devices in the solid state.File in questo prodotto:
