Abstract
A metal air battery having multiple anode-cathode disc assemblies that include a first and second cathode disc flanking an anode disc. An actuator moves at least one cathode disc relative to the other cathode disc, and thereby facilitates the size of the anode-cathode gap. The anode disc has a hole that engages a power shaft to rotate the anode disc.
Claims20
A metal air battery comprising:
- a housing comprising an opening with a keyed power shaft disposed in the opening;
- a plurality of anode-cathode disc assemblies disposed within the housing each anode-cathode disc assembly comprising;
- a first cathode disc, wherein the keyed power shaft is disposed within a first circular hole of the first cathode disc;
- a second cathode disc, wherein the keyed power shaft is disposed within a second circular hole of the second cathode disc;
- an actuator directly connected to both the first cathode disc and the second cathode disc, the actuator configured to change a magnitude of a gap between the first cathode disc and the second cathode disc;
- a rotating anode disc disposed between the first cathode disc and the second cathode disc, wherein the keyed power shaft is disposed within a keyed hole of the rotating anode disc such that rotation of the keyed power shaft rotates the rotating anode disc, the keyed hole being non-circular;
- the housing further comprising at least one access port configured to provide a liquid, a gas or an electrical connection to the plurality of anode-cathode disc assemblies.
