Abstract
An alkaline electrochemical cell having a barium compound additive in the anode according to one embodiment, and in both the anode and the cathode according to another embodiment. The anode of the present invention comprises an active anode material such as zinc, and an anode additive comprising a barium compound, such as barium sulfate in the amount of up to 8% by weight of active anode materials. According to another embodiment, the cathode of the electrochemical cell comprises an active cathode material, such as manganese dioxide, and also has an additive comprising a barium compound, such as barium sulfate. The anode and cathode of the present invention are particularly adapted for use in an electrochemical cell having an alkaline electrolyte.
