Multi-tab battery cycle life extension through alternating electrode charging

Abstract:

Systems, methods, and apparatus for a multi-tab battery cycle life extension through alternating electrode charging are disclosed. In one or more embodiments, a battery comprises a plurality of battery cells. The battery further comprises a plurality of anode electrodes and a plurality of cathode electrodes, of each of the battery cells, arranged around a perimeter of the battery. Further, the battery comprises a controller to apply, for each of the battery cells, a load or a charge from the anode electrodes to the cathode electrodes in a pattern such that charge is uniformly distributed across each of the battery cells. In one or more embodiments, the controller is located external or internal to the battery. In some embodiments, the battery further comprises a processor to determine the pattern for applying the load or the charge from the anode electrodes to the cathode electrodes for each of the battery cells.
