Title: Inexpensive cross-linked polymeric separators made from water-soluble polymers

Abstract

Polyvinyl alcohol (PVA) cross-linked chemically with aldehyde reagents produces membranes which demonstrate oxidation resistance, dimensional stability, low ionic resistivity (<0.8 /OMEGA/-cm/sup 2/), low zincate diffusivity (1x10/sup -7/ mols/cm/sup 2//-min), and low zinc dendrite penetration rate (>350 min) which make them suitable for use as alkaline battery separators. They are intrinsically low in cost, and environmental health and safety problems associated with commercial production appear minimal. Preparation, property measurements, and cell test results in Ni/Zn and Ag/Zn cells are described and discussed. 4 refs.
