As a preferred technical scheme, the middle part of the positive pole lug is bent, and one end, far away from the positive pole aluminum foil, of the positive pole lug is elastically connected to the battery cover.
The utility model has the advantages that: the rapidly-formed hard-shell button type battery is simple in production process, high in manufacturing efficiency, convenient to install and capable of saving manufacturing materials.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and examples.
FIG. 1 is an overall cross-sectional view of a rapid prototyping hard shell button cell of the type described in the examples;
fig. 2 is a structural diagram of each layer after unpacking the battery cells according to the embodiment.
In fig. 1 to 2:
1. a positive aluminum foil; 2. a negative copper foil; 3. a positive electrode tab; 4. a negative electrode tab; 5. a first diaphragm; 6. a second diaphragm; 7. an electric core; 8. a housing; 9. a battery cover.
Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
As shown in fig. 1 to fig. 2, in this embodiment, a fast-forming hard-shell button battery includes a positive aluminum foil 1, a negative copper foil 2, a positive tab 3, a negative tab 4, a first diaphragm 5, a second diaphragm 6, a housing 8 and a battery cover 9, where the first diaphragm 5 is located between the positive aluminum foil 1 and the negative copper foil 2, the second diaphragm 6 is located on one side of the negative copper foil 2 away from the positive aluminum foil 1, the first diaphragm 5, the negative copper foil 2 and the second diaphragm 6 are sequentially bonded and wound into a battery cell 7 with the positive aluminum foil 1 as the inside, the battery cell 7 is placed inside the housing 8, an opening is provided on the housing 8, the battery cover 9 covers the opening, the positive tab 3 is fixed on the positive aluminum foil 1, the negative tab 4 is fixed on the negative copper foil 2, the middle part of the negative electrode lug 4 is bent, and one end, far away from the negative electrode copper foil 2, of the negative electrode lug 4 is elastically connected to the shell 8.
Compared with the existing button cell, the use of adhesive is reduced, in the installation process of the cell, the negative pole tab 4 only needs to be bent for one time, two times or three times, then the cell 7 is placed in the shell 8, so that the outer end of the negative pole tab 4 is pressed against the inner side wall of the shell 8, and due to the elasticity after bending, the cell 7 can be relatively fixed with the shell 8, so that the stability of the adhesive is not needed, and the cell cover 9 is covered for packaging, and then the finished button cell can be completed.
More specifically, a coating film is coated on the outer side of the battery cell 7, and the positive electrode tab 3 and the negative electrode tab 4 both penetrate through the coating film.
The middle part of the positive electrode tab 3 is bent, and one end, far away from the positive electrode aluminum foil 1, of the positive electrode tab 3 is elastically connected to the battery cover 9.
Certainly, not only be limited to the negative pole utmost point ear 4 is buckled, anodal utmost point ear 3 is also buckled, covers after the battery cover 9, anodal utmost point ear 3 also elasticity is pushed up on the battery cover 9, only need the battery cover 9 with the fixed back of casing 8, anodal utmost point ear 3 also can with the battery cover 9 switches on.
It should be noted that the above embodiments are only preferred embodiments of the present invention and the technical principles applied, and any changes or substitutions which can be easily conceived by those skilled in the art within the technical scope of the present invention are covered by the protection scope of the present invention.
