Abstract: Embodiments of the present application provide a battery and an electrical device. The battery comprises: a box body including an electrical cavity; a battery cell accommodated in the electrical cavity and provided with a pressure relief mechanism on a first wall of the battery cell; a first passage and a second passage, the first passage and the second passage being configured to be able to communicate with the inside of the battery cell through the pressure relief mechanism when the pressure relief mechanism is actuated, wherein the first passage is used to discharge the emissions discharged from the pressure relief mechanism into the electrical cavity, and the second passage is used to discharge the emissions discharged from the pressure relief mechanism out of the electrical cavity.

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: Embodiments of the present application provide a battery, a power consumption apparatus, and a method and apparatus for producing a battery. The battery includes: a battery cell, provided with a pressure relief mechanism, the pressure relief mechanism being configured to be actuated when an internal pressure or temperature of the battery cell reaches a threshold, to relieve the internal pressure; a bus component, configured to be electrically connected to the battery cell; an electrical cavity, configured to accommodate the battery cell and the bus component; a collecting cavity, configured to collect emissions from the battery cell when the pressure relief mechanism is actuated; and a sealing structure, disposed in an airflow path formed between the pressure relief mechanism and a wall of the electrical cavity and configured to prevent the emissions from reaching the bus component when the pressure relief mechanism is actuated.

Abstract: The embodiments of the present application provide a method, apparatus and system for thermal runaway processing and a storage medium. The method first obtains a battery parameter for each of a plurality of battery modules in a power battery pack, then determines that a thermal runaway is occurred in a first battery module based on the battery parameter for each of the plurality of battery modules; and then obtains a second battery module based on the first battery module, wherein the second battery module corresponds to at least one battery module excluding the first battery module in the power battery pack; and finally supplies power to a chiller system with the second battery module.
