摘要： A battery and an electric device are provided. The battery includes a first box portion, a second box portion, a battery cell, and an insulating liquid. The first box portion and the second box portion fit together to define an accommodating space. The battery cell is accommodated in the accommodating space. The battery cell is provided with an electrode terminal and a pressure relief mechanism. The electrode terminal is closer to the first box portion relative to the pressure relief mechanism. The pressure relief mechanism is configured to be actuated when an internal pressure or temperature of the battery cell reaches a threshold, to release the internal pressure or high-temperature gas. The insulating liquid is provided in the accommodating space and immerses the pressure relief mechanism. When the insulating liquid is provided in the accommodating space, the first box portion is located above the second box portion.
