Abstract

The possibility of using composite films based on polyvinyl alcohol (PVA) and Na-carboxymethylcellulose (Na-CMC) as a separating material is considered for nickel-zinc and silver-zinc batteries. The sorption properties and porous structure of PVA/Na-CMC composite films treated with potassium hydroxide, as well as the electrochemical characteristics of nickel-zinc battery cells (open circuit voltage, average discharge voltage, charge retention) were investigated. The fundamental possibility of using PVA/Na-CMC composite films instead of a cellulose hydrate film is shown as a separating material for nickel-zinc and silver-zinc batteries.

聚乙烯醇与羧甲基纤维素钠复合膜的分离

摘要

对于镍锌和银锌电池，考虑使用基于聚乙烯醇（PVA）和Na-羧甲基纤维素（Na-CMC）的复合膜作为隔离材料的可能性。研究了用氢氧化钾处理的PVA / Na-CMC复合膜的吸附性能和多孔结构，以及镍锌电池的电化学特性（开路电压，平均放电电压，电荷保持率）。显示了使用PVA / Na-CMC复合膜代替水合纤维素膜的基本可能性，作为镍锌和银锌电池的隔离材料。
