Abstract
A battery and a method for its operation are described. The battery comprises a metal-air battery with an air cathode having opposed surfaces supported for simultaneous exposure of a first surface to air and a second surface to liquid electrolyte and a metal anode positioned in spaced juxtaposed relation to the second cathode surface to define therewith an anode-cathode gap for receiving electrolyte to form an anode-cathode pair electrically coupled by electrolyte. The battery contains an alkaline electrolyte and seed particles adapted to decrease passivation of the anode during discharge of the battery.
