1. A battery, comprising:
a battery cell, the battery cell being of a cylinder shape, a cylindrical side surface of the battery cell being provided with a pressure relief mechanism, the pressure relief mechanism being configured to be actuated, in response to an internal pressure or temperature of the battery cell reaching a threshold, to relieve the internal pressure of the battery cell;
an electrical chamber configured to accommodate the battery cell;
a collection chamber configured to collect emissions from the battery cell when the pressure relief mechanism is actuated; and
an isolation component configured to isolate the electrical chamber from the collection chamber, wherein the isolation component comprises a first region and a second region, the first region is used for accommodating a first portion of the battery cell such that the first portion protrudes, towards the collection chamber, from a surface of the second region facing towards the collection chamber, and the pressure relief mechanism is disposed in a region of the cylindrical side surface located in the first portion such that the emissions are allowed to enter the collection chamber when the pressure relief mechanism is actuated.
