1. A battery, comprising:
a battery cell comprising a pressure relief mechanism, the pressure relief mechanism being disposed on a first wall of the battery cell, and the pressure relief mechanism being configured to be actuated when an internal pressure or temperature of the battery cell reaches a threshold, to relieve the internal pressure; and
an electrical chamber configured to accommodate the battery cells;
a collection chamber configured to collect emissions from the battery cell when the pressure relief mechanism is actuated;
a thermal management component configured to isolate the electrical chamber from the collection chamber, and to accommodate a fluid to adjust a temperature of the battery cell, a first surface of the thermal management component being attached to the first wall, and the thermal management component being provided with a pressure relief zone, so that emissions discharged from an inside of the battery cell are capable of being discharged through the pressure relief zone to the collection chamber when the pressure relief mechanism is actuated;
wherein the first wall is provided with a first restraint member, the thermal management component is provided with a second restraint member, and the first restraint member and the second restraint member are arranged to be mated, so that the pressure relief mechanism is arranged opposite to the pressure relief zone.
