1. A battery, comprising:
a battery cell comprising a pressure relief mechanism, the pressure relief mechanism being arranged in a first wall of the battery cell, and the pressure relief mechanism being configured, when an internal pressure or temperature of the battery cell reaches a threshold, to be actuated to release the internal pressure; and
a thermal management component for containing a fluid to adjust a temperature of the battery cell;
wherein a first surface of the thermal management component is attached to the first wall, when the pressure relief mechanism is actuated, emissions from the battery cell are discharged toward the thermal management component, and the thermal management component is configured to be capable of being damaged when the pressure relief mechanism is actuated, so that the fluid is discharged from inside of the thermal management component;
wherein the thermal management component is provided with a second through hole therein, the second through hole being configured such that emissions discharged from the battery cell can pass through the thermal management component via the second through hole when the pressure relief mechanism is actuated;
wherein a radial dimension of the second through hole gradually decreases in a direction away from the pressure relief mechanism.
