Abstract
This invention teaches an elongate air depolarized electrochemical cell. The cell has a cathode, including an air cathode assembly, and a separator disposed inwardly of the air cathode assembly. A bottom member defines a bottom of the cell. An anode cavity, defined inwardly of the separator and the bottom member, receives a mass of electroactive anode material. An elongate hollow tube anode current collector is in electroactive contact with the mass of electroactive anode material. The anode current collector preferably has an enlarged cross-section such that the average distance between the anode current collector and the separator is reduced, thereby to reduce the overall mass of electroactive anode material used in the cell.
