[0017] During the process of assembling the battery, the soft-pack battery cell 14 and the protection board 13 are fixed inside the cylindrical steel shell 16 through the connection between the head shell 2 and the cylindrical steel shell 16.
[0018] The charging and discharging of the soft-pack battery cell 14 are realized through the protection board 13, and at the same time, short-circuit protection is carried out on the soft-pack battery cell 14; The positive electrode tab 6 is connected to the protection board 13, and the negative electrode of the soft-pack battery cell 14 is connected to the protection board 13 through the cylindrical steel shell 16 and the negative nickel sheet 4, so that the positive and negative electrodes of the battery are located at one end of the battery.
