Description
Technical field
The utility model relates to technical field of lithium ion, particularly relates to a kind of core and arc lithium battery of arc lithium battery.
Background technology
Lithium battery has the outstanding advantages such as operating voltage is high, specific energy is large, self discharge is little because of it, is originally widely used in numerous areas, particularly in the electronic product such as mobile phone, computer and wrist-watch.Square coiling type lithium battery is a kind of common lithium battery, by rectangular strip negative plate, barrier film and positive plate stacks successively and the core reeled is prepared from.In order to better be applicable to consumer demand, be convenient to the use of consumer, existing electronic product is designed to body mechanics's structure more, now needs arcuate structure lithium battery being designed to specific arc.
In prior art, the pole piece design of coiling type lithium battery all adopts horizontal scroll mode to carry out, and namely lug spot welding direction is laterally parallel with pole piece, and this kind of mode is applicable to conventional rectangular lithium ion battery, is unsuitable for bending being shaped as arcuate structure; And arc lithium ion battery because it needs to carry out longitudinal bending to battery after battery roll core is carried out, due to routine winding method bend time due to winding edge seriously stressed, not easily bending and bending after large to inside battery structural deterioration.
Summary of the invention
One of the purpose of this utility model is to avoid weak point of the prior art and provides the core to the little arc battery of inside battery structural damage after a kind of bending, and the arc battery made by it ensures good serviceability.
It is little and ensure the arc battery of good serviceability to inside battery structural damage after two of the purpose of this utility model is to avoid weak point of the prior art and provides a kind of battery roll core to bend.
The purpose of this utility model is achieved through the following technical solutions:
A kind of core of arc lithium battery is provided, comprise positive plate, negative plate and the barrier film be arranged between described positive plate and negative plate, described positive plate, described barrier film and described negative plate are superimposed and make described core by the mode of winding, described core is arranged to arcuate shape along the two ends of coiling direction, the tail end of described positive plate is welded with anode ear and the bearing of trend of described anode ear is parallel to the bearing of trend of described positive plate, the tail end of described negative plate is welded with negative electrode lug and the bearing of trend of described negative electrode lug is parallel to the bearing of trend of described negative plate.
Preferably, described core is arranged to semicircular arc shape along the two ends of coiling direction.
Preferably, described core is arranged to semiellipse arcuate shape along the two ends of coiling direction.
Preferably, the weld of described anode ear and described negative electrode lug is provided with adhesive-layer.
The utility model also provides a kind of arc lithium battery, comprises the battery cell that above-mentioned core is moulded through arc-shaped bend.
the beneficial effects of the utility model:
The core of arc lithium battery of the present utility model, the barrier film comprising positive plate, negative plate and be arranged between positive plate and negative plate, positive plate, barrier film and negative plate are superimposed and make core by the mode of winding, core is arranged to arcuate shape along the two ends of coiling direction, the tail end of positive plate is welded with anode ear and the bearing of trend of anode ear is parallel to the bearing of trend of positive plate, and the tail end of negative plate is welded with negative electrode lug and the bearing of trend of negative electrode lug is parallel to the bearing of trend of negative plate.When making arc battery, the welding of anode ear and negative electrode lug is carried out again after first completing the winding of core, thus the consistency of the ending of anode ear and negative electrode lug in guarantee winding process, the core of said structure is adopted to mould the arc battery made through arc, during its winding, core Width two edges are parallel with the longitudinal direction of battery, make core when bending, positive plate and negative plate lateral stressed, resistance is not produced during the bending of its two ends, and the radian formed after bending not easily rebounds, therefore little to inside battery structural damage after core bending, ensure that the serviceability that arc battery is good.

Embodiment
With the following Examples and accompanying drawing the utility model is described in further detail.
The core of a kind of arc lithium battery of the present utility model, as depicted in figs. 1 and 2, the barrier film 2 comprising positive plate 1, negative plate 3 and be arranged between positive plate 1 and negative plate 3, positive plate 1, barrier film 2 and negative plate 3 are superimposed and make core by the mode of winding, core is arranged to arcuate shape along the two ends of coiling direction, the tail end of positive plate 1 is welded with anode ear 5 and the bearing of trend of anode ear 5 is parallel to the bearing of trend of positive plate 1, and the tail end of negative plate 3 is welded with negative electrode lug 4 and the bearing of trend of negative electrode lug 4 is parallel to the bearing of trend of negative plate 3.
Concrete, core is arranged to semicircular arc shape or semiellipse arcuate shape along the two ends of coiling direction, adopt this arcuate shape, carry out arc mould prepare arc lithium battery time, because core two ends are circular shape, positive plate 1 and negative plate 3 superpose uniform force between the lamination that formed, prevent lamination from damaging due to unbalance stress, the phenomenon of preventing short circuit, and the shape of semicircular arc and semiellipse arc is convenient to relative sliding, more be conducive to moulding of arc, be convenient to the lithium battery forming arcuate structure.
Concrete, the weld of anode ear 5 and negative electrode lug 4 is provided with adhesive-layer, for fixing anode ear 5 and negative electrode lug 4.
When making arc battery, the welding of anode ear 5 and negative electrode lug 4 is carried out again after first completing the winding of core, thus the consistency of the ending of anode ear 5 and negative electrode lug 4 in guarantee winding process, the core of said structure is adopted to mould the arc battery made through arc, during its winding, core Width two edges are parallel with the longitudinal direction of battery, make core when bending, positive plate 1 and negative plate 3 lateral stressed, resistance is not produced during the bending of its two ends, and the radian formed after bending not easily rebounds, therefore little to inside battery structural damage after core bending, ensure that the serviceability that arc battery is good.
Finally should be noted that; the restriction of above embodiment only for illustration of the technical solution of the utility model but not to the utility model protection range; although be explained in detail the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement, and not depart from essence and the scope of technical solutions of the utility model.
