Abstract
The utility model discloses a kind of semi-finished product structure of ultra-thin polymer lithium ion battery, comprise multiple battery core, upper film and lower film; Described multiple battery cores are equidistant, being arranged between film and lower film and at the periphery of each battery core of interval carries out heat-seal; Lug in multiple battery core stretches out the top margin of film and lower film.Because multiple battery core can disposablely be placed between upper film and lower film by the utility model, by closedtop, side seal, fluid injection, the first underseal, bleed, change into, the step such as second time underseal, disposablely can produce multiple lithium ion battery, production efficiency is high, good product consistency.
Description
Technical field
The utility model relates to field of batteries, particularly relates to a kind of semi-finished product structure of ultra-thin polymer lithium ion battery.
Background technology
Lithium ion battery, since last century, the nineties exploitation was come out, within the short more than ten years, has obtained and has developed rapidly.Ultra-thin polymer lithium ion battery has the advantages such as energy density is higher, cycle life is better, therefore enjoys favor.As shown in Figure 1, lithium ion battery forms primarily of shell 1 ' and battery core 2 ', and battery core 2 ' is wrapped in shell 1 ', and traditional lithium ion battery is produced, and be mostly single processing, production efficiency is low.
Summary of the invention
The purpose of this utility model is to provide the semi-finished product structure of the ultra-thin polymer lithium ion battery that a kind of production efficiency is high.
For achieving the above object, technical solution of the present utility model is:
After adopting such scheme, because multiple battery core can disposablely be placed between upper film and lower film by the utility model, by closedtop, side seal, fluid injection, the first underseal, bleed, change into, the step such as second time underseal, disposablely can produce multiple lithium ion battery, production efficiency is high, good product consistency.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the front view of lithium ion battery;
Fig. 2 is three-dimensional exploded view of the present utility model;
Fig. 3 is front view of the present utility model;
Fig. 4 is the installation diagram of the utility model battery core and lower film.
Embodiment
As shown in figs 2-4, the utility model is a kind of semi-finished product structure of ultra-thin polymer lithium ion battery, comprises six battery cores 1, upper film 2 and lower film 3.
Six described battery cores 1 are equidistant, being arranged between film 2 and lower film 3 and at the periphery of each battery core of interval carries out heat-seal; Lug 11 in six battery cores 1 stretches out the top margin of film 2 and lower film 3.
In the utility model, the position of its heat-seal is as follows: the upper film 2 at six battery core 1 tops and lower film 3 are provided with closedtop 41, upper film 2 six battery core 1 both sides and lower film 3 are provided with side seal 42, during upper film 2 bottom six battery cores 1 and lower film 3 are provided with, envelope 43, is provided with underseal 44 at upper film 2 and the base of lower film 3, the below of middle envelope 43.
In order to ensure the accurate of upper film 2 and lower film 3 position, be all provided with location hole 21,31 in the both sides of upper film 2 and lower film 3.
Encapsulated moulding technique of the present utility model, comprises the following steps:
(1) mounted box location:
(2) closedtop: upper film 2 and lower film 3 are carried out heat-seal with the top of multiple battery cores 1 of wrapping up in it, forms closedtop 41;
(3) side seal: carry out heat-seal to the both sides of multiple battery core 1, forms side seal 42;
(4) fluid injection;
(5) bleed;
(6) first time underseal: upper film 2 and lower film 3 are carried out heat-seal with the bottom of the multiple battery cores 1 be wrapped between the two, form underseal 44;
(7) change into, survey appearance;
(8) second time underseal: according to the length of battery core 1, carries out heat-seal to upper film 2 and lower film 3 with the middle part of multiple battery cores 1 of wrapping up in it, seals 43 in formation;
The above, be only the utility model preferred embodiment, therefore can not limit with this scope that the utility model implements, the equivalence namely done according to the utility model claim and description change with modify, all should still belong in scope that the utility model patent contains.
