Beschreibung
Zusammenfassung:	The invention provides a special-shaped battery cell die cutting method and a special-shaped battery packaging method. The die cutting method comprises the step of carrying out die cutting on a positive pole piece or a negative pole piece according to the shape of a special-shaped battery cell and the shape of the special-shaped battery cell through a 90-degree anticlockwise rotating symmetrical shape. The special-shaped battery packaging method comprises the following steps: obtaining the special-shaped positive electrode cell and the special-shaped negative electrode cell by adopting the die cutting method; and sequentially laminating the special-shaped positive electrode battery cell and the special-shaped negative electrode battery cell to obtain a naked battery cell, and sequentially welding, packaging, baking, injecting liquid, forming, secondary sealing, grading capacity, OCV and detecting the naked battery cell to obtain the lithium ion battery. The die cutting method is particularly suitable for the
