BATTERY CELL AND ELECTRIC DEVICE

Abstract

An electrode assembly includes a first electrode plate group and a second electrode plate group stacked along a first direction. Along a second direction, a length of the first electrode plate group is greater than a length of the second electrode plate group, the second direction is perpendicular to the first direction. The first electrode plate group includes a first electrode plate closest to the second electrode plate group, where the first electrode plate includes a current collector. The current collector includes a first region and a second region, both sides of the first region are provided with an active material layer, the second region is provided with the active material layer only on a side facing away from the second electrode plate group. The first region at least partially overlaps with the first electrode plate group.
