Embodiment
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
Fig. 1 is the structural representation of the encapsulating structure of a kind of new type lithium ion battery provided by the invention, and Fig. 2 is for using the surface structure schematic diagram of the polymer Li-ion battery encapsulating material that forms after the encapsulation process of the present invention.
Referring to Fig. 1, Fig. 2, the invention provides a kind of encapsulating structure of new type lithium ion battery, include left side end socket 10 and right side end socket 20, described left side end socket 10 and the 20 lateral symmetry settings of right side end socket, has material 30 to be packaged between described left side end socket 10 and the right side end socket 20, described left side end socket 10 and right side end socket 20 have encapsulation plane 40 respectively in a side in opposite directions, have intermeshing sawtooth 41 on described two encapsulation planes 40.
In the present invention, being not limited to be provided with intermeshing sawtooth 41 on described two encapsulation planes 40, can also be other joggled structure, for example, and intermeshing a plurality of grooves of symmetry and projection.
Referring to Fig. 2, Fig. 3, the right-hand member of described material 30 to be packaged has the packaging belt 31 as position to be packaged in the lump, and described packaging belt 31 is placed with encapsulation plane 40 symmetries on described left side end socket 10 and the right side end socket 20.For the present invention, in view of having intermeshing sawtooth 41 on described two encapsulation planes 40, therefore, by the sawtooth 41 on left side end socket 10 and the right side end socket 20, described material 30 to be packaged is encapsulated, after encapsulation, can on this packaging belt 31, form an inside and have several uniformly-spaced packaging areas of striped, at this moment the indentation structure can take place repeatedly to bend in the encapsulating material in the packaging belt 31.
Need to prove that in the prior art, with good two the direct pressing of the end socket materials to be packaged of flatness, formed packaging belt zone is smooth, if the end socket distortion, the imprecise problem of pressing appears in packaging belt zone easily.Compared with prior art, the present invention is on the described left side end socket 10 that is used for pressing material to be packaged and the plane that is in contact with one another of right side end socket 20, process the sawtooth or the striped that are laminated, thereby make that being clipped in the material to be packaged that seals between two end sockets can repeatedly bending take place along with the sawtooth or the striped of left side end socket 10 and right side end socket 20, and increased the area that encapsulates, can avoid because the not closely generation of situation problem of the pressing that the encapsulation header distortion causes.
On the specific implementation, the present invention can process by the encapsulation plane to a pair of end socket, makes to encapsulate to occur intermeshing, that the depth is identical groove and projection on the plane; So,, configure on the packaging machine encapsulation parameters such as package temperature earlier, then material to be packaged is put into pressing between these two end sockets, and made two end sockets be laminated, then can realize treating the purpose that encapsulating material encapsulates in when encapsulation.After encapsulation, referring to Fig. 2, on the direction of parallel cells packaging belt, formed a plurality of striped traces, referring to Fig. 3, at the section of vertical packaging belt, packaging belt is ripple fluctuating shape, and encapsulating material is repeatedly bent, and packaging effect is good.
Therefore, the present invention has a plurality of advantages: 1, can utilize intermeshing sawtooth or striped on the encapsulation plane of end socket, treat encapsulating material and repeatedly bend, increase the area of encapsulation; 2, by changing the result of end socket, can solve the problem of end socket distortion, even left side end socket 10 and right side end socket 20 these two end sockets deform, so after encapsulating, it is the difference that the packaging belt 31 interior sawtooth that form have the depth on the material 30 to be packaged, but can not influence packaging effect, whole packaging belt does not have the imprecise position of pressing; 3, workable, applicability is good, can improve the fail safe of large tracts of land encapsulation greatly; 4, by the improvement of end enclosure structure, can reduce parameters such as package temperature, improve the security performance of battery; 5, material to be packaged is after encapsulation, and formed packaging belt trace is obvious, and the easy operating workman judges the stitching state of encapsulating material, thereby knows the packaging effect of polymer Li-ion battery, and it is visual to make packaging effect realize.
In sum, compared with prior art, the encapsulating structure of a kind of new type lithium ion battery provided by the invention, it can encapsulate polymer Li-ion battery effectively, guarantees the package quality of battery, strengthens the sealing of battery, improve the security performance of polymer Li-ion battery greatly, and then the whole serviceability of raising battery, the market application foreground of expansion battery production producer product is of great practical significance.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
