Abstract
The utility model discloses a polymer Li-ion battery, which comprises a shell, an electrical core arranged in the shell, a positive pole lug, a negative pole lug and a insulating bonding layer sleevedon the lugs, wherein the positive pole lug and the negative pole lug penetrate through the same insulating bonding layer and extend into the electrical core. The positive pole lug and the negative pole lug are inserted into the same insulating bonding layer, so the positive pole lug and the negative pole lug are in an integral mode, and the width between the two lugs can be reduced so as to makethe width of the finished battery smaller without affecting the sealing performance of the battery.

Technical field
The utility model relates to battery, especially polymer Li-ion battery.
Background technology
At present, as shown in Figure 1, the used lug of polymer Li-ion battery all adopts the monomer lug, i.e. corresponding dielectric adhesive layer of each lug, because monomer lug width minimum is wanted 1.5mm, the overall width that adds after the dielectric adhesive layer will reach more than the 2.5mm.Simultaneously in order not influence the sealing of battery, generally to keep the above distance of 2mm between the dielectric adhesive layer of positive and negative lug, therefore, the overall width minimum that electric core two lugs contain after the dielectric adhesive layer can only be accomplished 7mm, thereby the width of made finished product battery is difficult to accomplish below the 9mm.In addition, adopt single lug welding, battery pole ear centre-to-centre spacing is difficult to control, influences efficient and the rate of finished products of follow-up welding PCB.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of polymer Li-ion battery, and its positive and negative lug adopts Contiuum type, not only can reduce the width between two lugs, does the finished product cell widths littler, and does not influence the sealing of battery.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of polymer Li-ion battery comprises housing, places housing interior electric core, positive pole ear, negative lug, is enclosed within the dielectric adhesive layer on the lug; Described positive pole ear and negative lug link into an integrated entity by same dielectric adhesive layer.The lug of employing Contiuum type not only can reduce the width between two lugs, does the finished product cell widths littler, and does not influence the sealing of battery.
As improvement, the length of described dielectric adhesive layer is L, 3.0mm≤L≤10.0mm; Width is D, D 〉=3.0mm, and the length of dielectric adhesive layer and width directly influence the size of finished product battery, select the dielectric adhesive layer of different specifications, no matter can prepare the lithium ion battery of different size, be the lithium ion battery of what specification, and its two lugs centre-to-centre spacing can be effectively controlled.
As further improvement, described 4.0mmmm≤D≤10.0mm.
As improvement, described dielectric adhesive layer is PP or PE layer.
As improvement, described negative lug is nickel strap, copper strips or ambrose alloy composite band, and positive pole ear is an aluminium strip.
The beneficial effect that the utility model is compared with prior art brought is:
Positive and negative lug inserts in the same dielectric adhesive layer, makes positive and negative two lugs become Contiuum type, not only can reduce the width between two lugs, does the finished product cell widths littler, and does not influence the sealing of battery; In addition, two lug centre-to-centre spacing are fully by disjunctor lug decision, tolerance can be controlled in ± 0.2mm in.

Embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in Figure 2, a kind of polymer Li-ion battery comprises housing (indicate), places electric core 4 in the housing, the negative lug 2 of the positive pole ear 1 of aluminum, nickel material, is enclosed within the dielectric adhesive layer 3 of the PP material on the lug.Described positive pole ear 1 passes same dielectric adhesive layer 3 with negative lug 2 and stretches in the electric core 4, and positive and negative electrode lug 1,2 becomes Contiuum type.The positive and negative electrode lug 1,2 of polymer Li-ion battery is the tape shape, the width of lug generally has the specification of 0.5mm, 1.0mm, 1.5mm, the side of dielectric adhesive layer 3 is generally 0.5mm apart from the width of lug, distance between the lug is generally more than or equal to 1.0mm, the present embodiment value is 1.0mm, and tolerance is generally ± 0.2mm.When the width of lug was 0.5mm, the width D of dielectric adhesive layer 3 was 0.5mm+0.5mm+1.0mm+0.5mm+0.5mm=3.0mm; When the width of lug was 1.0mm, the overall width D of dielectric adhesive layer 3 was 1.0mm+1.0mm+1.0mm+0.5mm+0.5mm=4.0mm; When the width of lug was 1.5mm, the width D of dielectric adhesive layer 3 was 0.5mm+1.5mm+1.0mm+1.5mm+0.5mm=5.0mm.As required, can suitably enlarge the distance between two lugs, when the distance between two lugs was 6.0mm, the width D of dielectric adhesive layer 3 was 10.0mm.The length of described dielectric adhesive layer is L, 3.0mm≤L≤10.0mm, and the length and the width of suitable selection dielectric adhesive layer can be made into the micro cell of different size.
Following table is that the size that the utility model adopts disjunctor lug and traditional lug to make battery compares:
| Project | The test example | Comparative Examples |
| The lug type | The disjunctor lug | The monomer lug |
