Description
Technical field
The utility model relates to battery tools, particularly relates to the quick lamination device of a kind of lithium ion battery.
Background technology
In today of new forms of energy research extensive use, lithium ion battery more and more occupies critical role, but for power lithium-ion battery, its high power capacity required, makes gradually making emphasis to be turned on laminated type lithium ion battery in industry.
The lithium battery of traditional employing takeup type core strueture can not meet the high performance requirement of high power capacity, take core as starting point because of its takeup type structure, reel after positive and negative electrode being isolated by barrier film, at this moment the structure of lithium ion battery cell is the mid portion that positive and negative lug is arranged on battery core, positive and negative plate and lug thereof and barrier film successively reel to same direction, this structure battery is because tab welding is in inside, the yielding surface irregularity that causes even produces groove, and lug place easily produces short circuit phenomenon.
After adopting takeup type battery core on the other hand, positive/negative plate due to needs repeatedly curling catadioptric, both positive and negative polarity active material is easy to peel off from collector, the pole powder come off can cause and pierces through barrier film, connect both positive and negative polarity, produce internal short-circuit phenomenon, moreover coiled battery needs tension force when overcoming winding, be difficult to continue again to thicken active material, be also just difficult to the requirement meeting high-performance high power capacity.
Utility model content
In order to solve problem in prior art, the utility model provides the quick lamination device of a kind of lithium ion battery, comprise: positive pole ear positioning strip, negative lug positioning strip, pressing plate, described pressing plate is slab construction, a positive pole ear positioning strip and a negative lug positioning strip are one group of positioning strip, pressing plate is arranged and organizes positioning strip more, positive pole ear positioning strip and negative lug positioning strip are disposed on pressing plate.
As further improvement of the utility model, described positive pole ear positioning strip and negative lug positioning strip are disposed on the marginal position of pressing plate.
As further improvement of the utility model, described pressing plate is arranged three to seven group positioning strips.
As further improvement of the utility model, described pressing plate is arranged four groups of positioning strips.
Utilize the quick lamination device of lithium ion battery of the present utility model to carry out lamination process simply, easily operate, multiple battery core can be folded simultaneously, greatly reduce costs, improve lamination speed.The utility model carries out the laminated type core strueture that lamination obtains, and relative to monomer lamination, utilizes punching location, can not allow pole piece generation play, avoid the appearance of internal short-circuit of battery phenomenon.
The utility model carries out the laminated type core strueture that lamination obtains, and there will not be leakage to put pole piece (positive and negative) phenomenon, also there will not be and cause having negative or positive electrode to repeat phenomenon in battery core.
Accompanying drawing explanation
Fig. 1 is the quick lamination device structural representation of a kind of lithium ion battery of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Laminated type lithium ion battery, is mainly separately laminated by multiple positive plate a and multiple negative plate b barrier film c.
As shown in Figure 1, Fig. 1 is the quick lamination device of a kind of lithium ion battery of the utility model, in Fig. 1,1 is positive pole ear positioning strip, 2 is negative lug positioning strip, 3 is pressing plate, described pressing plate 3 is slab construction, for laying positive plate, negative plate and barrier film, barrier film, positive plate, barrier film, negative plate, barrier film, positive plate, barrier film, negative plate is placed successively, and place according to regular repetition of order above, when placement, positive plate positive pole ear positioning strip (1) is located, negative plate negative lug positioning strip 2 is located, a positive pole ear positioning strip (1) and a negative lug positioning strip 2 are one group of positioning strip, pressing plate 3 is arranged and organizes positioning strip more, three groups of positioning strips are depicted in Fig. 1, also can be 4 groups, 5 groups, 6 groups etc., arrange like this and organize positioning strip more, can organize when placement barrier film more and place simultaneously, finally cut.
The quick lamination device of a kind of lithium ion battery of the present utility model is utilized to carry out the method for the quick lamination of lithium ion battery as follows:
The battery core of lithium ion battery by positive and negative plate and between play buffer action barrier film form, according to the barrier film of technological requirement width be cut into uniform sizes length (length as required simultaneously folded how many battery cores and determine).The pole piece cut (positive/negative plate need punch at lug place) is put on the workbench that can locate, first, 1. cathode pole piece a is located on the table, negative plate is put into the barrier film b cut, then, then positive plate c be placed on workbench assigned address location.Last according to technological requirement, (a, b, c, b, a, b, c) technique are simple, easily operate, and can fold multiple battery core simultaneously, greatly reduce costs, and improve lamination speed for repeatable operation.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection range of the present utility model.
