1. A battery comprising:
a battery cell, provided with a pressure relief mechanism configured to be actuated in response to internal pressure or temperature in the battery cell reaching a threshold, to release the internal pressure;
a collection pipe configured to accommodate a firefighting medium; and
a firefighting pipe configured to connect to the collection pipe to allow the firefighting medium to be fed to the firefighting pipe, the firefighting pipe being configured to discharge the firefighting medium toward the battery cell in response to the pressure relief mechanism being actuated;
wherein two ends of the firefighting pipe are a first end and a second end respectively, the first end is configured to connect to the collection pipe to allow the firefighting medium to enter the firefighting pipe through the first end, and the second end is closed, wherein the firefighting pipe is higher than the collection pipe in a direction of gravity, so as to block the firefighting medium in the collection pipe when the pressure relief mechanism is not actuated.
