1. A battery cell, comprising:
an electrode assembly;
a housing provided with an accommodating space for accommodating the electrode assembly, wherein the housing comprises a first side plate located on a side in a first direction; a pressure relief mechanism disposed on the first side plate; and
a cover assembly for sealing the housing,
wherein an inner surface of the first side plate of the housing is provided with a first flow channel extending along the inner surface, and the first flow channel is configured to guide a gas in the accommodating space to the pressure relief mechanism so that the pressure relief mechanism is actuated when a pressure reaches a threshold, and relieves the pressure; and
the first flow channel comprises a first intermediate flow channel and a first edge flow channel, the first edge flow channel extends along a circumferential edge of the inner surface of the first side plate and communicates with the accommodating space, and the first edge flow channel and the pressure relief mechanism are in communication through the first intermediate flow channel.
