Abstract
The present disclosure relates generally to an alkaline electrochemical cell, such as a battery, and in particular to an improved gelled anode suitable for use therein. More specifically, the present disclosure relates to a gelled anode containing a highly crosslinked polyacrylic acid gelling agent that enables the benefits associated with an electrolyte having a relatively low hydroxide (e.g., potassium hydroxide) content, such as enhanced cell discharge performance, to be achieved, while avoiding the problems commonly associated with electrolytes having relatively low hydroxide content (e.g., an unacceptable level of cell gassing during discharge and/or a negative impact on discharge performance under certain load conditions including, for example, continuous load conditions).
