BATTERY, AND RELATED DEVICE, PREPARATION METHOD AND PREPARATION APPARATUS THEREOF

The present application discloses a battery, and a related device, preparation apparatus thereof. The battery includes a battery cell, the battery cell including a pressure relief mechanism and at least two walls, the at least two walls including a first wall and a second wall that intersect with each other, the pressure relief mechanism being disposed at the first wall and being configured to, when an internal pressure or temperature of the battery cell reaches a threshold, be actuated to release the internal pressure; a thermal management component attached to the first wall and being configured to accommodate a fluid to cool the battery cell; and a support component attached to the second wall, and configured to support the battery cell; wherein the thermal management component is configured such that when the pressure relief mechanism is actuated, emissions discharged from the battery cell pass through the thermal management component.
