Embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
embodiment 1.
As shown in Figure 3, a kind of aluminum plastic film of polymer Li-ion battery, it comprises aluminum plastic film body 1, described aluminum plastic film body 1 is provided with the core body groove 2 of the core body for encapsulating polymer Li-ion battery, it also comprises symmetrically arranged two the doubling grooves 3 of center line 4 along aluminum plastic film body 1, and described two doubling grooves 3 comprise a doubling groove 31 and a doubling tongue 32.
In use, the core body of polymer Li-ion battery is encased in core body groove 2, then by aluminum plastic film body 1 doubling, during doubling, coordinated with doubling tongue 32 by doubling groove 31, edging 5 is alignd after doubling can be made, guarantee there will not be dislocation, avoid aluminum plastic film wrinkling and the phenomenons such as gas rises, leakage that cause polymer Li-ion battery to occur, ensure the quality of polymer Li-ion battery, ensure its outward appearance and the stability of size.In addition, doubling groove 31 and doubling tongue 32 are aimed at by operating personnel, coordinating just can by neat for aluminum plastic film body 1 doubling, operating personnel do not need can carry out doubling operation under the state of high concentration energy, reduce the labour intensity of operating personnel, there is when doubling operates the effect of fool proof.
The area of doubling groove 3 described in the present embodiment is less than the area of described core body groove 2, and in certain scope, the area of doubling groove 3 is less, and the cooperation of doubling groove 31 and doubling tongue 32 is tightr, there will not be dislocation after more ensureing aluminum plastic film body 1 doubling.
Doubling groove 3 described in the present embodiment and the distance of the center line 4 of aluminum plastic film body 1 are greater than the distance of the center line 4 of described core body groove 2 and aluminum plastic film body 1, certain distance is provided with between doubling groove 31 and doubling tongue 32, aim at when being convenient to doubling operation, coordinate, enhance productivity.
Described in the present embodiment, doubling groove 3 is square, easy punch forming; Certainly, doubling groove 3 also can be the shapes such as circle, triangle, ellipse, the shape not circumscribed of doubling groove 3.
embodiment 2.
As shown in Figure 4, the difference of the present embodiment and embodiment 1 is: described in the present embodiment, core body groove 2 is two, and described two core body grooves 2 are symmetrical arranged along the center line 4 of aluminum plastic film body 1.
When the capacity of polymer Li-ion battery is larger, core body is also thicker, at this moment, center line 4 in aluminum plastic film body 1 is symmetrical arranged two core body grooves 2, during 1 doubling of aluminum plastic film body, two core body grooves 2 form larger accommodation space, can hold thicker core body, meet the needs of high capacity polymer lithium ion battery, the scope of application is wider.
Unaccounted feature in the present embodiment, adopts the explanation in embodiment 1, no longer repeats at this.
embodiment 3.
That prepares the aluminum plastic film of the polymer Li-ion battery of embodiment 1 rushes a shell side method, comprises following preparation process:
