摘要： The present application discloses a battery, a power apparatus, and a battery manufacturing method and device. The battery comprises a plurality of battery cells arranged in a first direction, each of the battery cells is provided with a plate-shaped electrode terminal along an end surface in the first direction, and two of the battery cells are provided with two of the electrode terminals between two opposite end surfaces that are arranged opposite to each other in the first direction. In the thickness direction of the electrode terminals, two of the electrode terminals are configured to be at least partially stacked and fixedly connected between the two end surfaces to implement the electric connection between two of the battery cells. By fixedly connecting the electrode terminals of the battery cells directly, the electric connection between two battery cells is implemented, thereby simplifying the electric connection structure between the battery cells, and reducing various risks caused by the arrangement of a bus component.
