Battery, power consumption device, method and device for preparing a battery

A power consumption device, comprising a battery;

• wherein the battery comprises:
• a battery cell comprising a pressure relief mechanism, at least a portion of the pressure relief mechanism protruding outward from 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 thermal management component is attached to the first wall of the battery cell, the first surface of thermal management component is provided with an avoidance chamber, and the avoidance chamber is configured to accommodate the at least portion of the pressure relief mechanism;
• wherein the thermal management component is configured to be capable of being damaged by the emissions when the pressure relief mechanism is actuated;
• wherein a bottom wall of the avoidance chamber is provided with a weakened zone, and the weakened zone is configured to be capable of being damaged by emissions discharged from the battery cell when the pressure relief mechanism is actuated, so that the emissions pass through the weakened zone;
• and
• wherein the weakened zone has a thickness less than or equal to 3 mm.
