    Abstract: A explosion-proof valve body of a battery has an opening region, which is provided with an explosion-proof notched groove at the edge thereof. The explosion-proof notched groove comprises a first straight line section, two arc sections and at least one second straight line section. Two ends of the first straight line section are connected to the two arc sections, respectively; at least one of the ends of the second straight line section is connected to the arc section; and the first straight line section is arranged parallel to the second straight line section. In a depth direction of the explosion-proof notched groove, an orthographic projection of the opening region is in an oblong shape. An outer edge of the orthographic projection of the opening region is a predetermined opening boundary, and the area of the orthographic projection of the opening region is S, where S=a×b+π×b2/4, S≥80 mm2, and b≥6 mm.

    Abstract: This application provides a battery. The battery includes a housing and a plurality of accommodating cavities located in the housing. Two adjacent accommodating cavities are isolated by a partition plate, and an electrode core assembly comprising at least one electrode core is arranged in the accommodating cavity. A plurality of electrode core assemblies are sequentially arranged along a first direction and connected in series. A liquid guiding hole and a gas guiding hole are provided on the partition plate. The liquid guiding hole and the gas guiding hole are used to connect two adjacent accommodating cavities at both sides of the partition plate. The battery further includes a blocking mechanism that enables the liquid guiding hole to be in a settable state including an open state and a closed state.
