Battery cells are presented that have notched electrodes. In one embodiment, the battery cells have a first notch in an electrode and a second notch in a seal. The second notch allows a first portion of the seal adjacent the first edge to fold without overlapping a second portion of the seal adjacent the second edge. The first notch serves as a relief zone that enables the seal to maintain a seal distance during folding. In another embodiment, the battery cells have a first notch in an electrode and a second notch in a portion of a separator. The first notch and the second notch, in combination, allow the separator to fold along a fold line without tearing. Other battery cells are presented.
