摘要： An electrochemical device includes a shell, an electrode post, and an electrode assembly. A through-hole is provided on the shell. The electrode post is disposed on the shell and at least partially accommodated in the through-hole. The electrode post is electrically connected to the electrode assembly. A frangible portion is provided at a position corresponding to the through-hole on the electrode post. The frangible portion is configured to be burst open when a pressure in the shell reaches a threshold, so as to implement communication between inside and outside of the shell to relieve the pressure. Provided on the electrode post, the frangible portion can be broken when the pressure in the electrochemical device reaches the threshold, so as to relieve the pressure in the electrochemical device.

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.
