This application relates to a battery, an electric apparatus, and a method and an apparatus for manufacturing a battery. The battery includes a plurality of battery cells and an insulation part. The plurality of battery cells are electrically connected by a busbar; and the battery cell includes a pressure relief mechanism, and the pressure relief mechanism is configured to be actuated when internal pressure or temperature of the battery cell reaches a threshold, to release the internal pressure. The insulation part is configured to cover the busbar, to prevent emissions from the battery cell from causing short circuit of at least one battery cell when the pressure relief mechanism is actuated.

Battery, electric apparatus, and method and apparatus for manufacturing battery

A battery, a power consumption device, and a method and device for producing a battery are disclosed. The battery includes: a first battery cell and a second battery cell adjacent to each other, the first battery cell including a pressure relief mechanism disposed on a first wall of the first battery cell; a fire-fighting pipeline configured to discharge a fire-fighting medium toward the first wall when the pressure relief mechanism is actuated; and a blocking component protruding from the first wall along a direction perpendicular to the first wall, and the blocking component being configured to block the fire-fighting medium discharged from the fire-fighting pipeline from flowing from the first battery cell to the second battery cell to improve the safety performance of the battery.

Battery, power consumption device, and method and device for producing battery

The present application provides a fire-fighting apparatus, a box assembly, a battery, a power consumption apparatus, and a method for preparing a battery. The fire-fighting apparatus includes: a pipe, a gas release mechanism, and a blocking structure. The pipe has an air inlet end and an air outlet end, and the air inlet end is configured to be connected to the battery, so that a combustible gas generated in the battery during thermal runaway events is capable of entering the pipe from the box via the air inlet end and being discharged from the pipe via the air outlet end; and the gas release mechanism is configured to be connected to the pipe and release a fire-fighting gas into the pipe when thermal runaway occurs in the battery; and the blocking structure is configured to block the combustible gas and the fire-fighting gas and change a flow direction.
