Abstract

A battery cell (100), a battery (1000) comprising same, and an electric device. The battery cell (100) comprises: a casing (10), the casing having an accommodating cavity (11), the accommodating cavity (11) having a first wall and a second wall which are oppositely arranged in a first direction, and an explosion-proof valve being provided on the first wall; and air guide plates (20), the air guide plates (20) being arranged in the accommodating cavity (11) and located between the first wall and the second wall, an air guide channel and vent holes (23) being formed in each air guide plate (20), the air guide channel extending in the first direction, and the air guide channel being communicated with the accommodating cavity (11) outside the air guide channel by means of the vent holes (23). According to the battery cell, a large discharge space is formed for gas generated in a cycle process of the battery cell, thereby reducing the probability of thermal runaway of the battery cell and reducing the risk of weld cracking of the casing caused by excessive pressure. In addition, a moving direction of the gas can be defined, and the gas generated in the cycle process of the battery cell is guided, so that the gas can be smoothly discharged, thereby improving the gas discharge effect.
