Problems solved by technology

[0003] In current batteries, when a battery cell undergoes thermal runaway, emissions will be generated inside the battery cell, including high-temperature smoke (in severe cases, open flames) and volatilized high-temperature electrolyte and other substances. These emissions During the discharge process, thermal diffusion will occur, which will cause thermal runaway of other battery cells, and even cause explosions and other accidents.

Abstract

The invention relates to the technical field of batteries, in particular to a battery, an electric device and a method and equipment for preparing the battery. The invention aims to solve the problemthat accidents are easily caused due to difficulty in pressure relief of emissions during thermal runaway of a battery. The battery includes a battery cell including a pressure relief mechanism for actuating to release an internal pressure when the internal pressure or temperature of the battery cell reaches a threshold value. The battery further comprises a fire-fighting cavity, a collecting cavity and an isolating part, wherein the isolating part is used for isolating the fire-fighting cavity from the collecting cavity and can be penetrated by the discharged material when the pressure reliefmechanism is actuated, so that the discharged material enters the collecting cavity through the fire-fighting cavity. The invention further discloses an electric device using the battery. The batterydisclosed by the embodiment of the invention has the beneficial effects of collecting emissions generated by the thermal runaway battery monomers while extinguishing fire, and reducing the occurrenceof safety accidents.

Description

technical field [0001] The present application relates to the technical field of batteries, in particular to a battery, an electrical device, a method and equipment for preparing the battery. Background technique [0002] In a device that uses electric energy as the driving energy, the battery is its core component. Ensuring the safety of the battery is crucial to ensuring the safety of the device as a whole, and the thermal runaway of the battery is an important factor that threatens the safety of the battery. [0003] In current batteries, when a battery cell undergoes thermal runaway, emissions will be generated inside the battery cell, including high-temperature smoke (in severe cases, an open flame) and volatilized high-temperature electrolyte and other substances. These emissions Thermal diffusion will occur during the discharge process, which will cause thermal runaway of other battery cells, and even cause explosions and other accidents.
