Rechargeable metal air electrochemical cell incorporating collapsible cathode assembly

摘要

The rechargeable metal air electrochemical cell generally includes a pair of air cathode portions centrally disposed and attached to each other with a collapsible mechanism. Anodes are disposed in ionic communication with each air cathode portions via a suitable electrolyte. For recharging, a pair of third charging electrodes is provided ionic communication with the anode portions.
