Abstract
A lithium-and-manganese flexible packaging battery air bag structure is characterized in that the section of the air bag structure is trapezoid, and one side close to a battery cavity is an inclined line and provided with a right-trapezoid-shaped section. According to the lithium-and-manganese flexible packaging battery air bag structure, the lithium-and-manganese flexible packaging battery air bag forming structure is improved, the section of an air bag is trapezoid, the edge close to the battery cavity is slope-shaped and accordingly can guide electrolyte, and therefore the electrolyte can enter the battery cavity, and the problem of insufficient battery cell electrolyte absorption amount is solved.
Description
Technical field
The utility model relates to disposable lithium manganese aluminum plastic film flexible-packed battery industry, and more particularly it is a kind of lithium manganese flexible-packed battery airbag structure.
Background technology
In today that digital electronic goods are propagated its belief on a large scale, the application of polymer Li-ion battery has been deep into the every nook and cranny of our daily life, be subjected to the impact of secondary flexible packaged battery pool technology, the flexible-packaged lithium manganese cell in the disposable lithium-manganese cell system is also developed rapidly.The same with the technique of secondary cell, one time lithium manganese flexible-packed battery also adopts the mode in aluminum plastic film punching hole to make battery case, and leave air bag on the battery cavities next door, when battery encapsulates for the first time, battery to be placed in air bag mode up, electrolyte is injected by air bag one side, treat to be absorbed by battery core through after a while storage electrolyte, inside battery is extracted the gas of inside battery and unnecessary electrolyte out after reaching preliminary chemical balance in air bag, finish final encapsulation and cut away air bag.Traditional inside air bag space is the cuboid of standard, finishes the conventional softer battery pack airbag structure of first encapsulation as shown in Figure 1.
There is following deficiency in the air bag of traditional structure: because electrolyte at first is injected in the air bag, two-layer aluminum plastic film between air bag and the battery cavities pastes very closely, cause electrolyte very narrow from the passage that air bag imports battery cavities, traditional air bag four limits and cell plane be state nearly all at right angles, the gravity of electrolyte self is largely born by the edge of air bag near battery cavities, the actuating force that may cause forcing electrolyte to flow into battery cavities downwards is not enough, it is too much the interior residual electrolyte of air bag so just may to occur, and the problem of the insufficient electrolyte of arrival battery cavities, the battery core imbibition is not enough can be impacted the performance of battery.
Summary of the invention
The purpose of this utility model is to overcome the weak point of above-mentioned existing background technology, and a kind of lithium manganese flexible-packed battery airbag structure is provided, and it can improve battery core imbibition effect.
The purpose of this utility model reaches by following measure: lithium manganese flexible-packed battery airbag structure, it is characterized in that its cross section is trapezoidal, and with the battery cavities nearside be oblique line.
In technique scheme, described cross section is right-angled trapezium.
The utility model has improved lithium manganese flexible-packed battery air bag molding structure, the air bag section is trapezoidal, and the edge close with battery cavities is ramped shaped, can play to electrolyte the effect of drainage, be conducive to electrolyte and enter battery cavities, avoided the problem of battery core liquid absorption deficiency.

Embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not consist of to restriction of the present utility model, only for example.Simultaneously by illustrating that advantage of the present utility model will become more clear and easily understanding.
The utility model lithium manganese flexible-packed battery airbag structure, its cross section is trapezoidal, and with the battery cavities nearside be oblique line 6.
Further, the cross section is right-angled trapezium.
For finishing the flexible-packed battery airbag structure that the utility model proposes of first encapsulation, comprise battery cavities 1, section is trapezoidal air bag 5, be electrolyte passage 3 between the trapezoidal air bag 5 at battery cavities 1 and section, be positioned at the liquid injection port 4 that section is trapezoidal air bag 5 outsides, section be trapezoidal air bag 5 and battery cavities 1 nearside be oblique line 6(as shown in Figure 2).It has changed the conventional balloon inner space is the design feature (as shown in Figure 1) of the cuboid of standard.
The manufacturing process of the utility model lithium manganese flexible-packed battery airbag structure is as follows:
1., when making lithium manganese flexible-packed battery rushes the shell mould, shell mould air bag punch 9 width that rush of punching out air bag part are made half of rushing shell mould air bag die 10 width, and the part of vacancy is near battery cavities, only stay on one side in addition and cooperate necessary gap, mate fully and rush shell mould battery cavities punch 7 and rush shell mould battery cavities die 8 shapes, as shown in Figure 3.
2., combine mould and rush shell by normal procedure afterwards, the battery case air bag of institute's punching out partly is flexible-packed battery shell and the airbag structure figure that the utility model proposes, wherein battery cavities 1 and section are trapezoidal air bag 5 upwards, between battery cavities 1 and section are trapezoidal air bag 5, electrolyte passage 3 is arranged, it is oblique line 6 with battery cavities 1 nearside that section is trapezoidal air bag 5, as shown in Figure 4.
3., the manufacture craft of battery is consistent with traditional handicraft, battery core enter after shell and the preliminary encapsulation effect namely as shown in Figure 2.
Claims (2)
1. lithium manganese flexible-packed battery airbag structure is characterized in that its cross section is trapezoidal, and with the battery cavities nearside be oblique line.
2. lithium manganese flexible-packed battery airbag structure according to claim 1 is characterized in that its cross section is right-angled trapezium.
