Abstract: A battery cell, a battery pack and a vehicle. The battery cell comprises: a housing, which is provided with an inner cavity, and a first side wall and a second side wall, which are opposite each other, wherein an inner wall surface of the second side wall is configured to have a recess, which is recessed in a direction facing away from the inner cavity, the recess forms an air exhaust passage in the inner cavity, and the second side wall is provided with an explosion-proof hole, which corresponds to the air exhaust passage in terms of position; a terminal, which is arranged on a side wall of the housing other than the second side wall; an explosion-proof valve, which is mounted on the second side wall and is used for covering the explosion-proof hole; and an electrode core, which is arranged inside the housing and is spaced apart from the explosion-proof hole.

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.
