Zinc/air cell

The present invention provides a zinc/air button cell having an air spacer member within the air inlet space of the cathode can. The spacer member may be of solid plastic, rubber, or metal construction inserted into the air inlet space (plenum region) of the cathode can adjacent air holes in the can. The spacer member may be of disk-like configuration with cut out sections therein of varying configurations. The cut out sections in the spacer disk form channels of unoccupied free space underlying the air holes allowing air to pass unobstructed from the air holes to the cathode assembly. The channels of free space are generally much wider than the diameter of the air holes. The wide channels of unoccupied ''free space'' running between the air holes and cathode assembly improve air flow distribution to the cathode assembly. The spacer disk simultaneously provides sufficient support to the cathode assembly preventing it from bending into the cathode can air inlet space.
