Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The object of the present invention is to provide a kind of high injection electrolyte efficiency, the high speed of evacuation, electroless liquid to splash out pollution shell
The soft bag lithium ionic cell shell stamp structure of body.
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, soft bag lithium ionic cell shell stamp structure of the present invention includes the first sub- shell 1, the
Two sub- shells 2, naked battery core 3, airbag region 4, punching hole region 5, the first depressed section 6, the second sunk area 7.
First sub- shell 1 and the second sub- shell 2 form the first depressed section 6 after technique is cheated in punching, the first sub- shell 1 and the
Two sub- shells 2 are fastened and connected, the airbag region 4 that the first depressed section 6 forms punching hole region 5 and connect with punching hole region 5, punching hole
Place naked battery core 3, the gas that airbag region 4 is used to add electrolyte and generates when accommodating Battery formation in region 5.
