The Effect of Solid Solution of Inorganic Salts on the Conductivity of Solid Polymer Electrolytes
【摘要】 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“Polymer- 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 Li Cl O4 -脲 (物质的量比为 1∶ 4.5 ) -高分子体系室温电导率可达 1 .84×1 0 - 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
【Abstract】 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 LiClO 4 urea(mole ratio=1∶4.5) polymer can reach 1.84×10 -3 S/cm,and the study results show that solid solution of inorganic salts has important effect on the conductivity of SPE.
