Abstract: An insulation film configured to wrap at least a part of a shell of a battery cell is provided with a fragile portion configured to cover at least a part of a pressure relief mechanism in the battery cell mounted on the shell. The fragile portion is disposed on the insulation film and covers at least a part of the pressure relief mechanism, such that when the battery cell is thermally runaway, the insulation film less hinders the pressure relief mechanism.

Abstract: A battery cell includes an electrode assembly, a shell and an insulator. The shell is configured to accommodate the electrode assembly, where the shell includes a wall portion, and the wall portion is provided with a first pressure relief region configured to be opened when the battery cell is under thermal runaway. The insulator is at least partially disposed between the electrode assembly and the wall portion to dielectrically insulate the electrode assembly and the wall portion, where the insulator is provided with a second pressure relief region at a position corresponding to the first pressure relief region, and the second pressure relief region is configured to allow gas to reach the first pressure relief region through the insulator when the battery cell is under thermal runaway. When the battery cell is under thermal runaway, the second pressure relief region allows gas to be relieved of pressure through the insulator.

Abstract: 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.

Abstract: A safety regulation mechanism configured to perform a safety regulation on a battery includes a variable voltage generation module and a safety member. The variable voltage generation module is configured to establish a target voltage difference between the safety member and the battery. The target voltage difference causes the safety member to perform the safety regulation on the battery when an abnormality of the battery occurs.

Abstract: A safety control mechanism for performing safety control on a battery includes a voltage generation module and a safety member. The voltage generation module is configured to establish a voltage difference between the safety member and the battery. When the battery is abnormal, the voltage difference causes the safety member to perform safety control.
