ABSTRACT:
A zinc air-type battery comprising first and second cathodes each with positive contacts and an anode with a negative contact. The second cathode is situated proximal to the negative contact and proximal to the anode, which can enable air ingress to be substantially doubled and the internal resistance of the battery to be substantially halved, and further can provide for a relatively short diffusion length of ions from the second cathode.
