In some feasible implementations, the position to which glue is applied bypasses the third weak zone 931 when the fire prevention pipeline 70 is being bonded to the protection part 93, so that the emissions is able to break through the third weak zone 931 successfully.

FIG. 12 is a flowchart of a method for preparing battery according to some embodiments of this application. The battery is the battery according to the foregoing embodiments. This method applies to a device for preparing battery.

S101. Install a battery cell, where the battery cell is provided with an electrode terminal.

S102. Install a fastener and connect the fastener to the electrode terminal.

S103. Install a fire prevention pipeline and fasten the fire prevention pipeline to the fastener, where the fire prevention pipeline is configured to accommodate a fire prevention medium.

According to this embodiment, during the installation process, the fastener is connected to the electrode terminal, to fasten the fire prevention pipeline by using the fastener. Compared with the conventional technology, the fire prevention pipeline is reliably fastened, and easy to install and operate.
