Abstract
The utility model discloses a soft packaging electrokinetic cell which comprises a cell core, a positive pole ear, a negative pole ear and a packaging film, wherein the packaging film is rectangle and is provided with an H-shaped final encapsulation, and the positive pole ear and the negative pole ear extend from the upper part final encapsulation from the H-shaped final encapsulation. Insulation adhesive tapes are arranged among the packaging film, the positive pole ear and the negative pole ear. The soft packaging electrokinetic cell of the utility model makes use of the H-shaped encapsulation of a folded packaging film the superfluous edge trimming is reduced, and the material is saved. During the packaging process, the technological operation for pressing the packaging film is omitted, and the packaging process is simplified. Since various moulds are not need to be prepared, the production cost is reduced greatly. The production efficiency and the finished product quality are raised greatly particularly for the soft packaging electrokinetic cell with large thickness.
Description
Technical field
The utility model relates to the battery technology field, particularly a kind of flexible packaging power battery.
Background technology
At present, the three limits heat-sealing form that is packaged as that polymer Li-ion battery is commonly used.This packaged form normally adopts compression molding techniques, and first mould with certain specification is pressed into packaging film box-like, and the battery of then packing into is after closing in three limits, with hot pressing strip of paper used for sealing compacting involution.This method needs different moulds to the battery of different size, and production cost is higher.In addition, along with the increase of polymer lithium ion power cell capacity, cell thickness also increases thereupon.When using flexible packaging film to pack, be subjected to the restriction of packaging film ductility, cause the cracking of packaging material easily and influence useful life of battery.
The utility model content
The purpose of this utility model provides a kind of flexible packaging power battery of saving material, simplifying packaging process.
For achieving the above object, the utility model provides a kind of flexible packaging power battery, comprises battery, and positive and negative lug and packaging film, packaging film are rectangle and have sealing of " worker " font that the top that positive and negative lug is sealed by " worker " font is sealed and stretched out.
The utility model flexible packaging power battery is provided with the insulation adhesive tape between packaging film and the positive and negative lug.
The utility model flexible packaging power battery, packaging film are aluminum plastic film.
The utility model flexible packaging power battery, the useful technique effect of obtaining is: utilize packaging film doubling " worker " font seal package, reduced unnecessary cutting edge, saved material.In packaging process, saved the technological operation that packaging film is suppressed, simplified packaging process.Because needn't prepare multiple different mould, production cost is reduced greatly, improved production efficiency and end product quality.
Description of drawings
Fig. 1 is the common structural representation of present flexible packaging power battery;
Fig. 2 is the front view of the utility model flexible packaging power battery structure;
Fig. 3 is the rearview of the utility model flexible packaging power battery structure;
Fig. 4-Fig. 8 is the utility model flexible packaging power battery encapsulation method schematic diagram set by step.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
The utility model provides a kind of flexible packaging power battery, comprises battery, positive and negative lug 3 and packaging film 1, packaging film 1 for rectangle and have " worker " font seal 2, positive and negative lug seals 2 top by " worker " font and seals and stretch out.Be provided with insulation adhesive tape 4 between packaging film 1 and the positive and negative lug 3.
With reference to Fig. 2 and Fig. 3, in embodiment of the present utility model, packaging film 1 is an aluminum plastic film.
With reference to Fig. 4-Fig. 8, in the embodiment of the utility model flexible packaging power battery, the encapsulation process of flexible packaging power battery comprises the steps:
1) cut out the packaging film 1 of certain size, its width is a battery at the 2-3 of this direction size doubly, and its length is battery at the 1-2 of this direction size doubly, simultaneously with the mid portion on the upper edge edge of the sticking packaging film of insulation adhesive tape 4 envelopes;
2) doubling and overlap dual-side makes battery be close to this conduplication side 9 and fixes the position; With these conduplication side 9 hot sealings;
3) lug is stretched out along exposing from upper edge, after the good battery of embedding, with this upper edge along 5 hot sealings;
4) add electrolyte from lower edges 10;
5) with lower edges 10 hot sealings and vacuumize; This battery is after changing into, and hot sealing forms heat-sealing limit 8 and vacuumizes once more, carries out shaping at last, cuts out and goes unnecessary packaging bag, becomes the finished product battery.
With reference to Fig. 2, because the capacity of polymer power battery is big more, the thickness of its battery is also just big more, evagination 11 can appear in upper and lower two sealing parts of battery, and cell thickness is big more, its evagination part is just obvious more, but this can not exert an influence for the electrokinetic cell performance, has reached the intended purposes of the big thickness flexible package of high-capacity polymer electrokinetic cell.Utilize " worker " font seal package of packaging film doubling, reduced unnecessary cutting edge, saved material.In packaging process, saved the technological operation that packaging film is suppressed, simplified packaging process.Because needn't prepare multiple different mould, production cost is reduced greatly, improved production efficiency and end product quality.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; do not breaking away under the utility model design concept prerequisite; common engineers and technicians make the technical solution of the utility model in this area various modification and improvement; all should fall into protection range of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
