It can express or implicitly include one or more this feature.
Referring to Fig. 1, it is the sectional view of soft-package battery side seal end socket end socket 100 provided in an embodiment of the present invention.It is described
Soft-package battery side seal end socket 100 includes the first end socket 11 and the second end socket 12 being oppositely arranged with first end socket.At this
In embodiment, first end socket 11 sets fluted 111 towards the side of second end socket 12.The length of the groove 11
Degree can be adjusted according to the side edge length of soft-package battery 200 (ginseng Fig. 3) to be sealed.Preferably, the length of the groove 111
For the 25%~35% of 200 side edge length of soft-package battery.In addition, first end socket 11 and second end socket 12 are by Huang
Copper is into and then having stronger wearability.
Referring to Fig. 2, the flow chart of its soft-package battery mouth-sealing method provided in an embodiment of the present invention.It should be noted that
The method of the present invention is not limited to the order of following step, and in other embodiment, method of the invention can only include with
Under the step a portion, or part steps therein can be deleted.
Step S01, treats the Soft Roll electricity of sealing after the completion of closedtop and fluid injection using the soft-package battery side seal end socket 100
Once sealed in pond 200.
Referring again to Fig. 3, the soft-package battery 200 include airbag 21, the battery core 22 that is arranged in the airbag 21 and
Two poles 23 being connected with the battery core 22.One of pole 23 is Positive Poles, and another pole 23 is anode pole
Column.In the present embodiment, the battery core 22 is square-shaped, and the battery core 22 is close to the side of the airbag 21.Wherein, institute
It is aluminum plastic film to state airbag 21.
Further, that the soft-package battery 200 is once sealed is located proximate to the battery core 22, such as Tu3Zhong A areas
Shown in domain, since first end socket 11 sets fluted 111, once sealed to the soft-package battery 200
When, unencapsulated region L is left, wherein, the length of unencapsulated region L and the equal length of the groove 111.
Step S02, carries out the soft-package battery 200 vacuum and envelope and is honored as a queen in advance chemical conversion in vacuum in advance.
As shown in B area in Fig. 3, carry out vacuum in side of the airbag 21 away from the battery core 22 and seal in advance, and true
The standing of soft-package battery 200 is melted into by empty pre- be honored as a queen.
Step S03, carries out vacuum secondary sealing to complete pair in the region once sealed to the soft-package battery 200
The side seal of the soft-package battery 200.
It is appreciated that as shown in figure 4, the airbag 21 on the right side of sealing (C), the Soft Roll are cut off after the completion of vacuum secondary sealing
Battery 200 is i.e. plastic.
Battery sealing method provided by the present invention, adds a sealing step compared with now with technology, and then makes
Battery core 22 can be fixed up well, prevent in subsequent handling manual operation or the battery core 22 under pressure state from moving
It is dynamic, improve the accuracy of encapsulation.Further, since the angle position of soft-package battery 200 has the seal also not easily damaged.Further,
Due to using soft-package battery side seal end socket 100 provided by the invention in a sealing step so that after the completion of once sealing,
Unencapsulated region L is left in the position once sealed.Then the vacuum for carrying out airbag 21 is sealed in advance, vacuum is honored as a queen chemical conversion in advance, change
Vacuum secondary sealing is carried out in the region once sealed after, electrolyte and gas can pass through when this process vacuumizes
Unencapsulated region L discharges when once sealing, since unencapsulated region is smaller, electrolyte outflow region is small, the dirt of edge sealing
Dye degree substantially reduces, and then improves the stability and reliability of encapsulation.
