无机盐固熔体对高分子固体电解质电导率的影响

摘要

A new type of solid polymer electrolyte (SPE) “polymer-in-salt”has been discussed. The effects of different kinds,content,and structure of inorganic salts on the conductivity of SPE are studied. The conductivity of LiCIO4-urea(mole ratio= 1:4.5)-polymer can reach 1.84×10-3S/cm,and the study results show that solid solution of inorganic salts has important effect on the conductivity of SPE.%用无机盐和脲制成固熔体，加入PEG，PVA等高分子物质制备新型的“Poly-met-in-Salt”。研究了无机盐种类、含量、结构对高分子固体电解质(SPE)电导率的影响，制备的LiClO4-脲(物质的量比为1：4.5)-高分子体系室温电导率可达1.84×10-3S·cm-1。研究表明无机盐固熔体对SPE的电导率具有重要影响。
