Abstract: This application relates to batteries with an asymmetric design. At least some batteries described herein include two sections having different shapes and/or sizes, thus having different volumes. Having a battery formed with a relatively larger sections allows for several advantages. For example, the larger section can accommodate bending of a tab used to connect several electrodes together. Additionally, with the larger section providing space for the bent tab, the electrodes can be extended in, for example, the relatively smaller section. As a result, the battery can provide additional energy storage.
