BATTERY, ELECTRICAL DEVICE, AND METHOD AND DEVICE FOR PREPARING BATTERY

A battery, a power consumption device, and a method and device for producing a battery are provided, which could enhance the safety of the battery. The battery includes: a battery cell including a pressure relief mechanism configured to be actuated when an internal pressure or temperature of the battery cell reaches a threshold, to relieve the internal pressure; and a fire-fighting pipeline configured to accommodate a fire-fighting medium and discharge the fire-fighting medium when the pressure relief mechanism is actuated; where the fire-fighting pipeline is covered with an isolation layer, and the isolation layer is configured to block the contact of gases and the fire-fighting pipeline so as not to generate condensate. In a battery provided by an embodiment of the present application, a battery cell is provided with a pressure relief mechanism, when the pressure relief mechanism is actuated, emissions thereof may damage a fire-fighting pipeline, so that a fire-fighting medium in the fire-fighting pipeline flows out and flows to the battery cell, to lower a temperature of the battery cell; meanwhile, the fire-fighting pipeline is covered with an isolation layer, and the isolation layer may be configured to reduce the probability of forming condensate on the fire-fighting pipeline, thereby reducing or even eliminating the influence of the condensate on the battery and improving the safety of the battery.
