A thermal runaway trigger method relates to the technical field of batteries. The thermal runaway trigger method includes: providing a battery cell and a heating member arranged in the battery cell; and heating the inside of the battery cell by the heating member, so as to cause a thermal runaway of the battery cell. The heating member is arranged inside the battery cell, and the heating member heats the inside of the battery cell to cause the thermal runaway of the battery cell, so that the inside of the battery cell can be heated to cause the thermal runaway of the battery cell in a relatively short time. Due to the reduced internal space of the battery cell, the range of diffusion of the heating member inside the battery cell is small, and the heat loss of the heating member is relatively small.

Thermal runaway trigger method

A battery includes a cylindrical battery cell having a cylindrical side surface provided with a pressure relief mechanism, 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. The isolation component includes 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.
