1. A box of a battery, comprising:
an electrical chamber, configured to accommodate a plurality of battery cells, wherein at least one battery cell of the plurality of battery cells comprises a pressure relief mechanism, and the pressure relief mechanism is configured to be actuated when an internal pressure or a temperature of the battery cell provided with the pressure relief mechanism reaches a threshold value, to relieve the internal pressure;
a thermal management component, configured to accommodate a fluid to adjust the temperature of the plurality of battery cells; and,
a collection chamber, configured to collect emissions from the battery cell provided with the pressure relief mechanism when the pressure relief mechanism is actuated;
wherein the thermal management component is configured to isolate the electrical chamber from the collection chamber, a pressure relief region is disposed on the thermal management component, and the emissions collected in the collection chamber is discharged to the outside of the collection chamber after passing through the pressure relief region;
wherein the pressure relief region is staggered with the pressure relief mechanism, and
wherein the thermal management component is configured to be capable of making the emissions enter the collection chamber through the thermal management component when the pressure relief mechanism is actuated.
