[0027] In this embodiment, the shaping tool 10 can apply a preset pressure to the battery cell 20 installed in the battery cell installation position to shape the battery cell 20. The shaping tool 10 is installed in the heating area 31 of the auxiliary heating structure 30, and the auxiliary heating structure 30 is installed in the oven 40.
