Gel polymer electrolytes (GPEs) have drawn a lot of interest due to their special qualities, which include high conductivity that is comparable to liquid electrolytes, excellent mechanical stability, and high flexibility. Using the solution casting approach, we have synthesized copper ion conducting gel polymer electrolyte (GPE) films made of polyvinyl alcohol (PVA) as the polymer host. An ionic salt, copper sulphate (CuSO), and a plasticizing solvent, PANI/ [BMIM] [BF] polyionic liquid, were employed. The structural, electrical, and electrochemical properties of the GPE films were carefully examined. The significant XRD crystalline peak decreased and disappeared upon the addition of PANI/[BMIM] [BF] polyionic liquid, suggesting that PIL is a useful plasticizer for the PVA/HPMC polymers.

提高充电电池电解质用 PVA/HPMC/PANI/CuSO4 凝胶聚合物的离子电导率和电化学稳定性

凝胶聚合物电解质（GPE）因其特殊的品质而引起了广泛的关注，其中包括与液体电解质相当的高电导率、优异的机械稳定性和高柔韧性。采用溶液浇铸方法，我们合成了以聚乙烯醇（PVA）为聚合物主体的铜离子导电凝胶聚合物电解质（GPE）薄膜。使用离子盐硫酸铜 (CuSO) 和增塑溶剂 PANI/[BMIM][BF] 聚离子液体。对 GPE 薄膜的结构、电学和电化学性能进行了仔细检查。添加 PANI/[BMIM][BF] 聚离子液体后，显着的 XRD 结晶峰降低并消失，表明 PIL 是 PVA/HPMC 聚合物的有用增塑剂。
