POLYMER SOLID ELECTROLYTE

摘要

PURPOSE:To obtain an electrolyte with excellent ion conductivity and mechanical strength by setting the ratio of absorbance at the specific frequency of a cross-linking body to a fixed range in a polymer solid electrolyte using the polyethylene oxide bridge body as a polymer matrix. CONSTITUTION:A polymer solid electrolyte is constituted of ion conducting polymer and electrolyte salt serving as a carrier, ion conduction is realized when the electrolyte solvated in a polymer matrix is dissociated and diffused and moved in the matrix along electrolysis. In the polymer solid electrolyte using a polyethylene oxide cross-linking body as the polymer matrix, the polymer solid electrolyte obtained by selecting the characteristic so that the ratio between the absorbance of the 1R spectrum of the bridge body at 1280cm<-1> and the absorbance at 842cm<-1> is A1280/A842<=0.80 is excellent in ion conductivity and mechanical strength and is not colored.
