Abstract: An electrode assembly includes unit cells stacked in a longitudinal direction, each unit cell including an electrode structure, a separator, and a counter-electrode structure. The electrode structure includes an electrode current collector and an electrode active material layer. The counter-electrode structure includes a counter-electrode current collector and a counter-electrode active material layer. An end portion of the counter-electrode current collector extends past the counter-electrode active material and the separator. The end portion of the counter-electrode current collector is bent to define a bent end portion of the respective counter-electrode current collector. The bent end portions of at least some of the counter-electrode current collectors overlap the bent end portion of an adjacent counter-electrode current collector. The electrode assembly also includes a counter-electrode busbar extending across and attached to the bent end portions such that the counter-electrode current collectors are electrically connected to and are disposed inboard of the counter-electrode busbar.
