In some feasible implementations, the fire prevention pipeline 70 may be bonded to the separation part 92. For example, a structural adhesive may be used for bonding.

FIG. 11 is a schematic structural diagram of a fire prevention pipeline provided on a battery according to still another embodiment of this application. The main difference between this embodiment and the foregoing embodiment is that the battery is further provided with a protection part 93.

In some feasible implementations, the protection part 93 may be made of an insulation material. For example, the protection part 93 may be a mica layer.

The protection part 93 is laid on the separation part 92 and covers the electrode terminal 5 to prevent the electrode terminal 5 from being short circuited by the emissions or fire prevention medium. The fire prevention pipeline 70 is located on the protection part 93.

To avoid that the position of the pressure relief mechanism 6 is blocked and the pressure relief mechanism 6 is unable to be spouted open, and also to allow the fire prevention medium discharged from the fire prevention pipeline 70 to enter the battery cell 400 to implement a good fire prevention, the protection part 93 is further provided with a third weak zone 931, configured to allow the emissions from the battery cells to pass through when the pressure relief mechanism 6 is actuated, so that the fire prevention medium passes through the third weak zone 931 to destroy the fire prevention pipeline 70, and the fire prevention medium in the fire prevention pipeline 70 flows to the battery cell 400.
