Abstract

The utility model belongs to the technical field of batteries, and discloses a square flexibly-packaged lithium ion battery, which comprises a square cell body and tabs for extracting electric quantity. Tab sealing edges are arranged among the tabs and the cell body, lateral sealing edges are disposed at two edges of the cell body, and the tab sealing edges are folded and attached to the body. The length of the cell is reduced in the same length space, the space of the cell body can be enlarged, the effective volumetric specific energy of the cell is enhanced, and accordingly the volume of the battery is reduced compared with an existing battery with energy equivalent to that of the battery.

Description

A kind of square flexible packing lithium ion battery
Technical field
The utility model relates to a kind of flexible package column lithium ion battery, relates in particular to a kind of rectangular lithium ion battery that can effectively increase electric core volume specific energy.
Background technology
In the last few years, development along with battery technology, lithium ion battery has characteristics such as discharging current is big, good stability, fail safe is good, capacity is big and is widely used in the fields such as digital product, electric tool and power toy because of it, bring great convenience for our life.Along with the frivolous little development of digital product, energy is little, and bulky battery is more and more inapplicable.
Summary of the invention
Technical problem to be solved in the utility model provides the rectangular lithium ion battery that a kind of volume is little, the effective volume specific energy is high.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of square flexible packing lithium ion battery, comprise as core square electric core body partly and the lug of drawing electric weight, between lug and electric core body, the lug edge sealing is arranged, there is the side seal limit on electricity core body both sides, the described lug edge sealing body that is folded to and fits.
Further: in above-mentioned square flexible packing lithium ion battery, described side seal edge break to and the body of fitting.The knuckle that the front end on described side seal limit and the two ends of lug edge sealing the form lug edge sealing that is folded to and fits.
Compared with prior art, in the above-mentioned square flexible packing lithium ion battery, the described lug edge sealing body that is folded to and fits, further, its side seal limit body that also is folded to and fits.Adding man-hour, adopting accurate frock clamp that lug edge sealing and side seal limit are positioned bending, reducing electric core length, under the equal length space, electric core principal length can extend, and electric core effective volume specific energy is promoted.Thereby make that its volume reduces with the battery of homenergic.
Description of drawings
Fig. 1 is the rectangular cell structure chart that lug edge sealing and side seal limit do not have bending; Fig. 2 is the rectangular cell structure chart of lug edge sealing and side seal spring folding and applying body; Fig. 3 is the rectangular cell structure chart of lug edge sealing and side seal spring folding and applying body, knuckle bending and the lug edge sealing of fitting; Wherein 1 square electric core body, 2 lugs, 3 lug edge sealing, 4 side seal limits, 5 knuckles.
Embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with embodiment and accompanying drawing.
As Fig. 1-3: a kind of square flexible packing lithium ion battery, comprise as core square electric core body 1 partly and the lug 2 of drawing electric weight, between lug 2 and electric core body 1 lug edge sealing 3 is arranged, there is side seal limit 4 on electric core body 1 both sides, described lug edge sealing 3 body 1 that is folded to and fits.Described side seal limit 4 body 1 that is folded to and fits, as shown in Figure 2.The knuckle 5 that the front end on described side seal limit 4 and the two ends of lug edge sealing 3 the form lug edge sealing 3 that is folded to and fits, as shown in Figure 3.
Add man-hour, adopt accurate frock clamp that lug edge sealing and side seal limit are positioned bending, again with knuckle 5 bendings, and the lug edge sealing 3 of the bending of fitting.Under the equal length space, reduced electric core length, electric core principal space can strengthen, and electric core effective volume specific energy is promoted.Thereby make that its volume reduces with the battery of homenergic.
Above-mentioned only is preferred implementation of the present utility model, and in addition, the utility model can also have other implementations.That is to say that under the prerequisite that does not break away from the utility model design, any conspicuous replacement all should fall within the protection range of the present utility model.
