摘要： A cover plate assembly, a battery, and a method for assembling a battery are provided. The cover plate assembly includes a cover plate, a pole, and an explosion-proof assembly. The cover plate includes a cover plate body and a carrier portion. The cover plate body is disposed around an external periphery of the carrier portion. The carrier portion is recessed from a first surface of the cover plate body. The carrier portion and the cover plate body cooperatively define a first recess communicating with a first through hole defined by the carrier portion. The pole is disposed in the first recess. The pole abuts against the carrier portion. The explosion-proof assembly includes an explosion-proof valve and a protective sheet. The explosion-proof valve and the protective sheet are disposed in a second through hole defined by the pole. The explosion-proof valve is spaced apart from the protective sheet.

摘要： A top cover assembly for a battery, a battery, and an energy storage device are provided in the disclosure. The top cover assembly includes an insulating cover plate, a top cover plate, an insulating member, and a current collector stacked in sequence. A surface of the first flange close to the insulating member, an inner circumferential wall of the mounting hole, and a surface of the top cover plate close to the first flange and extending beyond the inner circumferential wall of the mounting hole define a sealing cavity. An inner circumferential wall of the through hole and an outer circumferential wall of the main body define a gap therebetween, the gap communicates with the sealing cavity, and a sealing member is received in the sealing cavity.

摘要： A top cover assembly for a battery, a battery, and an energy storage device are provided in the disclosure. The top cover assembly for a battery includes a pole and a pressing block. The pressing block defines a limiting hole. The pole extends through and is at least partially located in the limiting hole. The limiting hole has a first hole section and a second hole section axially connected with the first hole section. The first hole section has a radial size larger than the second hole section. In the top cover assembly for a battery according to implementations of the disclosure, the first hole section and the second hole section connected in the axial direction can make an inner circumferential wall of the limiting hole stepped.
