Embodiment Construction
[0015] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.
[0016] attached figure 1 The battery core of the external sheath of the wound lithium ion battery shown is a composite component, which includes a pressing plate 1 , a winding core 2 , a positive electrode sheet 3 , a negative electrode sheet 4 and an adhesive tape 5 . According to the structure of the winding battery, the positive electrode sheet 3 and the negative electrode sheet 4 arranged alternately are inserted in the cavity of the winding core 2, and the winding core 2 adopts a stacked installation structure. The pressing plate 1 is a component designed by the present invention, and it is used to clamp the stacked winding core 2 on the one hand, and is used to protect the battery core and pack the casing on the other hand. In this embodiment, the pressing plate 1 is 2.0 mm thick and made of PP material. The long and wide sides o...
