ALKALINE ELECTROCHEMICAL CELLS WITH SEPARATOR AND ELECTROLYTE COMBINATION

An alkaline electrochemical cell having an anode including electrochemically active anode material comprising at least 3.3 g of zinc or zinc alloy, a cathode including electrochemically active cathode material comprising 10 g to 11.5 g of manganese dioxide, a separator between the anode and the cathode, and an electrolyte comprising 25% to 35% by weight of an alkali hydroxide based on the total weight of the electrolyte. The separator in combination with the electrolyte may have an initial area-specific resistance between 100 mOhm-cm2 and 220 mOhm-cm2.
