Abstract:
An impact resistant wound cell comprises a first electrode plate with a first surface and a second surface. The first surface comprises a first active material area and a first current collector area, the second surface comprises a second active material area and a second current collector area. The first current collector area is located on an inner side of an outermost circle of the wound cell. In the first electrode plate, the second current collector area and the first current collector area are adjacent to and opposite to each other, the first current collector area and the second current collector area are bonded together by a first bonding member. The present disclosure further provides a battery using the wound cell.
