Abstract:
A battery includes a first mono cell formed from a first electrode foil having a first body and a first tab, and a first coating. The first body has long edges and short edges, and a length-to-width ratio of the first body is at least five. The first tab extends from one of the long edges of the first body entirely between one of the short edges a midpoint of the long edge. A second electrode foil has similar structure to the first electrode foil and coating, but a second tab is aligned opposite the first tab along the short edges. A second mono cell has similar structure. A third tab and a fourth tab of the second mono cell are on an opposing side of the midpoint of the long edges from the first tab and the second tab.
