摘要： A battery cover plate includes an electrode post plate, a hot-melt adhesive film, a cover plate assembly and a busbar. The cover plate assembly defines a first through hole; the electrode post plate and the busbar are located on two sides of the first through hole, a boss is arranged on the busbar, the boss is embedded in the first through hole, one end of the boss is connected with the electrode post plate. With the hot-melt adhesive film covered on the first through hole, the electrode post plate and the hot-melt adhesive film are placed on the first through hole; under the action of thermal pressing, the electrode post plate and the cover plate assembly are thermally fused together; the hot-melt adhesive film can further seal a part of the boss to fix the electrode post plate in a more reliable way.
