Abstract: A battery including a curved metal shell, a curved metal plate, and a curved electrode assembly. The curved metal shell has a curved surface and a plurality of side walls extending from the curved surface. The curved electrode assembly is disposed between the curved metal shell and the curved metal plate. The plurality of side walls are bound with the curved metal plate to seal the curved electrode assembly between the curved metal shell and the curved metal plate. By disposing a direction of an opening of the curved metal shell, the difficulty in the manufacturing process of the battery is greatly reduced, curved electrode assemblies in different structural forms are placed into the curved metal shell more conveniently and smoothly, and the energy density of the battery is also increased.

Abstract: 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.
