Abstract
The present disclosure generally relates to an alkaline electrochemical cell comprising an additive for improved discharge performance. The additive is a finely dispersed superabsorbent material comprising particles having a substantially uniform shape and a small particle size relative to typical materials used in alkaline cells. The superabsorbent material results in enhanced discharge performance of the alkaline cell by increasing access of zinc to the electrolyte.
