ALKALINE ELECTROCHEMICAL CELL WITH DENDRITE-INHIBITING SEPARATOR

摘要

A sealed alkaline battery cell is composed of a positive electrode, zinc-active negative electrode, electrolyte-absorbent separator and electrolyte in semi-dry amounts within the assembled cell. An essentially invariant interface between separator and adjacent negative electrode is attained by maximizing homogeneity of wetness to electrolyte along the interface and within the separator and minimizing the presence of occluded voids along the interface. The contents of the cell are spirally wound or otherwise stacked in a configuration under firm pressure.
