1. A case of a battery, comprising:
an electrical chamber configured to accommodate a battery cell, wherein the battery cell comprises a pressure relief mechanism;
a collection chamber configured to collect emissions from the battery cell provided with the pressure relief mechanism when the pressure relief mechanism is actuated; and
an isolating component configured to isolate the electrical chamber from the collection chamber,
wherein the isolating component is a thermal management component,
wherein the thermal management component is provided with a weakened zone, and the weakened zone is configured to be capable of being damaged when the pressure relief mechanism is actuated, such that the emissions from the battery cell provided with the pressure relief mechanism pass through the weakened zone and enter the collection chamber, and
wherein the thermal management component is provided with a recess arranged opposite to the pressure relief mechanism, and a bottom wall of the recess forms the weakened zone;
wherein the pressure relief mechanism is disposed at a first wall of the battery cell provided with the pressure relief mechanism, the first wall is attached to the thermal management component, and the recess is disposed on a surface of the thermal management component facing the first wall;
wherein the thermal management component comprises a first thermally conductive plate and a second thermally conductive plate, the first thermally conductive plate is located between the first wall and the second thermally conductive plate and attached to the first wall, a first region of the first thermally conductive plate is recessed toward the second thermally conductive plate to form the recess, and the first region is connected to the second thermally conductive plate.
