    Abstract: A battery cell (e.g., in a battery pack, or in a vehicle) comprises: a housing having an inner cavity, a first side wall, and a second side wall; a terminal post; an explosion-proof valve; and an electrode core. A first recess and a plurality of second recesses are arranged on an inner wall surface of the second side wall and are concave in a direction facing away from the inner cavity. The first recess forms a main air passage in the inner cavity. The plurality of second recesses form a plurality of branch air passages, separately communicating with the main air passage, in the inner cavity. The second side wall comprises an explosion-proof hole corresponding to a position of the main air passage. The explosion-proof valve is mounted on the second side wall. The electrode core is arranged in the housing and spaced apart from the explosion-proof hole.

    Abstract: A vehicle has a battery pack. The battery pack includes a battery or a battery module. The battery includes a battery shell and an explosion-proof valve. The explosion-proof valve is arranged on the battery shell. The volume of the battery is V, and the unit of V is mm3. The explosion-proof valve is provided with a notch groove, and the explosion-proof valve has an opening region. In a depth direction of the notch groove, an outer edge of the orthographic projection of the opening region is a predetermined opening boundary, the area of the orthographic projection of the opening region is S, and the unit of S is mm2. S and V satisfy 0.3 mm−1≤(5000×S)/V≤6 mm−1.
