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;
an isolation component;
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,
a protective component, wherein the protective component is located on one side of the isolation component away from the battery cell;
wherein the isolation component is configured to isolate the electrical chamber from the collection chamber, a pressure relief region is disposed on the isolation component, and the emissions collected by the collection chamber is discharged through the pressure relief region; and
wherein a high-temperature resisting material is pasted on a bottom wall of the protective component.
