Abstract: An explosion-proof valve comprises an explosion-proof valve body. which is provided with score grooves, and the score grooves comprise two first score grooves, two second score grooves, and one third score groove. One end of each of the two first score grooves and one end of each of the two second score grooves are respectively connected to two ends of the third score groove. The other ends of the two first score grooves extend in a direction away from each other, and the other ends of the second score grooves extend in a direction away from each other. The explosion-proof valve body comprises an opening area. In the depth direction of the score grooves, the outer edge of the orthographic projection of the opening area is a predetermined opening boundary, and the area of the orthographic projection of the opening area is (I), wherein S≥80 mm2, c≥4 mm, and α≥30°.

Abstract: A battery cell includes a housing having an inner cavity, a first side wall and a second side wall opposite to each other. The second side wall includes an explosion-proof hole. A first bottom support and a second bottom support are disposed in the inner cavity, support the electrode core, spaced apart from each other, and define a first gas channel. The second side wall support the first bottom support and the second bottom support. The explosion-proof hole communicates with the inner cavity through the first gas channel. A terminal post is disposed on a side wall of the housing other than the second side wall; An explosion-proof valve is mounted on the second side wall, and configured to cover the explosion-proof hole. An electrode core is disposed in the inner cavity, connected to the terminal post, and spaced apart from the explosion-proof hole.
