Sodium polyacrylate gelling agent for zinc gelled anode

摘要

A sodium polyacrylate superabsorbent polymer made by bulk polymerization and characterized as described herein is a superior gelling agent when provided at a suitable concentration in a gelled anode for an alkaline electrochemical cell. Suitable gelled anodes, alkaline electrochemical cells containing such gelled anodes, and methods for making and using same are also described.
