Abstract
A battery includes 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 is configured to discharge the firefighting medium toward the battery cell in response to the pressure relief mechanism being actuated. 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.
