Abstract
The utility model relates to lithium battery technical field, in particular to a polymer battery configuration which can increase battery capacity. A battery electrical core is connected with a pole ear seal edge at the front end, and the pole ear seal edge is folded along the electrical core front end face. The two sides of the pole ear seal edge need to be folded entad to guiding angle, or be cut with a right-angle notch, or cut a corner respectively at first, before the pole ear seal edge is folded along the electrical core front end face. For the polymer battery capacity increasing configuration provided by the utility model, the battery seal edge is folded airward along the electrical core front end face, which reduces the electrical core pole ear seal edge to the utmost extent and extend the space that the electrical core takes inside the battery, in order to increase the battery capacity.
Description
Technical field
The utility model relates to technical field of lithium batteries, is specifically related to a kind of electrostrictive polymer pool structure that increases battery capacity.
Background technology
And along with the development of lithium-ion electric pool technology, its cost performance improves constantly, and causes it by all trades and professions extensive use.Nearly one or two years,, indexs such as the capacity of lithium battery, charge-discharge performance are had higher requirement along with the develop rapidly of mechanics of communication.In order further to improve the capacity of battery, the battery research staff has made many innovations in the related fields such as connected mode of improving the polarity dope layer of pole piece collector, improvement pole-piece pole-ear.
Because the restriction of application, the shape size of the lithium battery of different model is normally certain.It is longer that the lug of the electric core 1 of present poly-lithium battery seals limit 2, as shown in Figure 1, for inner core is sealed in the composite package film, with on the lug that the both positive and negative polarity collector is connected lug glue is arranged, this lug glue is enclosed between two composite package films by heating, make inner core and external environment condition isolated, lug seals the limit and has just kept certain width.Because the size of encapsulation back finished product battery is fixed, lug seals certain width, can only dwindle the space that inner core occupies, thereby has limited the lifting of battery capacity.
The utility model content
Technical problem to be solved in the utility model provides a kind of shortening lug and seals the limit, improves the electrostrictive polymer pool structure of battery capacity.
For solving the problems of the technologies described above, the technical scheme that the utility model is realized is:
A kind of polymer battery increase-volume structure, the battery battery core front end is connected with lug and seals the limit, and lug seals the edge and electric core front end face and turn up.
When pasting electric core front end face and turning up lug and seal the limit, earlier lug is sealed the both sides, limit and inwardly be converted into lead angle respectively or lug is sealed meet at right angles shape breach or lug is sealed the both sides, limit respectively excise a jiao of both sides, limit excision.
The utility model has following remarkable result compared to existing technology:
The utility model provides polymer battery increase-volume structure, and battery seal edge electricity core front end face is upwards turned up, and the lug that has shortened electric core to greatest extent seals the limit, thereby enlarges the battery space that electric core occupies, and can effectively must improve the capacity of battery.

Fig. 3 is that lug seals the first kind structure chart of limit before not turning up among Fig. 2;
Fig. 4 is that lug seals the second kind structure chart of limit before not turning up among Fig. 2;
Fig. 5 is that lug seals limit the third structure chart before not turning up among Fig. 2.
Embodiment
Referring to Fig. 2～5, a kind of polymer battery increase-volume structure includes electric core 1, and the lug that electric core front end is a soldering polar ear seals limit 2, seals shared space, limit in order to shorten lug, effectively utilizes the space, lug is sealed the edge electric core front end face and turn up.When turning up lug and seal the limit, earlier lug is sealed the both sides, limit respectively to invagination, make flanging form chamfering 31, chamfering can be 45 degree, the also lead angle of other certain angles is referring to Fig. 3.Two corners are protected earlier during flanging, prevent that electric core packing film from damaging and cause defective products with tool.And then the battery that will roll the limit well is on the constant temperature make-up machine, earlier the neat lug root of battery compressed, and by isothermal block lug sealed the parallel face of edge break Cheng Yudian core front end face again.
The utility model is sealing lug before edge electricity core front end face turns up, and also lug can be sealed the excision of both sides, limit and meet at right angles behind the shape breach 32, wholely again turns up lug and seals the limit, referring to Fig. 4; Also lug can be sealed after the both sides, limit respectively excise one jiao 33, wholely again turn up lug and seal the limit, referring to Fig. 5
The utility model makes lug seal edge electricity core front end face and turns up, and has effectively shortened lug and has sealed shared space, limit, thereby can enlarge the battery space that electric core occupies, and promotes the capacity of entire cell.
Claims (4)
