Abstract
The utility model provides a prevent short circuit battery, includes by positive plate, negative pole piece and is in diaphragm between the two around rolling up the electric core that the needle was convoluteed and is formed, electric core outsourcing the plastic -aluminum membrane is equipped with, the one end of positive plate be connected with anodal ear, the one end of negative pole piece is connected with the negative pole ear, anodal ear be located the lateral wall that the positive plate is close to the outer end, the negative pole ear be located the lateral wall that the negative pole piece is close to the outer end, and anodal ear and negative pole ear are equipped with the difference in height along the thickness direction of battery. It effectively prevents contact between the utmost point ear, overlap joint to have to the advantage that can not lead to the battery short circuit.
Description
Technical field
The utility model relates to cell art, is specifically related to a kind of against short-circuit battery.
Background technology
Flexible-packed battery, its shell is aluminum plastic film, and be the soft packaging material of quality, its inside is coated with electrode slice and electrolyte etc., forms complete flexible-packed battery; Because the specification of flexible-packed battery is different, the aluminum plastic film covering cutting out different size size is needed to use, covering is generally rectangle, the flanging of middle reserved one fixed width, then the left and right sides turns down, middle flanging just forms the thickness of battery, and the place of twice turnover mutually overlaps and wherein forms battery by coated for the material such as electrode slice, electrolyte.
As shown in Figure 1, flexible-packed battery generally comprises aluminum plastic film 6 ', is enclosed with battery core in aluminum plastic film 6 ', and battery core is generally formed by winding by positive level sheet 3 ', negative plate 1 ' and barrier film, positive plate is provided with positive pole ear 4 ', and negative plate is provided with negative lug 2 '; Described positive plate and negative level sheet center have for reel volume pin 5 ', and its position of negative lug that the positive pole ear wherein positive plate arranged and negative plate are arranged all is positioned at inner side, is namely positioned at positive pole and negative pole on a side of volume pin; Such structure is in winding process, and because positive pole ear is generally aluminium foil, negative lug is generally nickel sheet and forms, and is easy to bend, be out of shape, once overlap between two lugs, will causes battery short circuit.
Utility model content
The utility model, for the above-mentioned deficiency of prior art, provides Contact, overlap joint that one effectively prevents lug, thus can not cause the against short-circuit battery of battery short circuit.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of against short-circuit battery, comprise by positive plate, negative plate and be in the battery core of barrier film therebetween around volume pin winding, aluminum plastic film is equipped with in described battery core outsourcing, one end of described positive plate is connected with anode ear, and one end of negative plate is connected with negative electrode lug; Described anode ear is positioned at positive plate on the lateral wall of outer end, and described negative electrode lug is positioned at negative plate on the lateral wall of outer end, and anode ear and negative electrode lug are provided with difference in height along thickness (highly) direction of battery.
Adopt said structure, because anode ear is positioned at positive plate on the lateral wall of outer end, described negative electrode lug is positioned at negative plate on the lateral wall of outer end, and anode ear and negative electrode lug are provided with difference in height along the thickness direction of battery.Spacing between anode ear and negative electrode lug is widened, thus reduces the chance of the two winding process collision, contact, thus the phenomenon also reducing battery short circuit occurs.
As preferably, described anode ear and the negative electrode lug difference in height of setting along the thickness direction of battery is as 0.04-0.1mm; Adopt the contact that this difference in height prevents therebetween further, reduce short-circuit risks; More preferably 0.05-0.08mm.
As preferably, described anode ear and negative electrode lug along battery Width between spacing (distance namely between the center line of anode ear broad ways and the center line of the negative electrode lug Width) 3/5-4/5 that is positive plate Breadth Maximum.More preferably 4/5; Adopt the contact that this structure can prevent therebetween further, reduce short-circuit risks.
Accompanying drawing explanation
The battery structure schematic diagram of this prior art of Fig. 1.
The structural representation of Fig. 2 the utility model against short-circuit battery.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail, but is not limited only to following examples.
As shown in Figure 2: a kind of against short-circuit battery, a kind of against short-circuit battery, comprise by positive plate 3, negative plate 1 and be in the battery core of barrier film therebetween around volume pin 5 winding, aluminum plastic film 6 is equipped with in described battery core outsourcing, one end of described positive plate is connected with anode ear 4, and one end of negative plate is connected with negative electrode lug 2; Described anode ear is arranged in positive plate on the lateral wall of outer end (outer end and accompanying drawing are near aluminum plastic film one end), described negative electrode lug is arranged in negative plate on the lateral wall of outer end (outer end and accompanying drawing near aluminum plastic film one end), and anode ear and negative electrode lug are provided with difference in height along thickness (highly) direction of battery.
Adopt said structure, because anode ear is positioned at positive plate on the lateral wall of outer end, described negative electrode lug is positioned at negative plate on the lateral wall of outer end, and anode ear and negative electrode lug are provided with difference in height along thickness (above-below direction as shown in drawings) direction of battery.Spacing between anode ear and negative electrode lug is widened, thus reduces the chance of the two winding process collision, contact, thus the phenomenon also reducing battery short circuit occurs.
Anode ear described in this practicality and the negative electrode lug difference in height of setting along the thickness direction of battery is as 0.04-0.1mm; Adopt the contact that this difference in height prevents therebetween further, reduce short-circuit risks; More preferably 0.05-0.08mm.
Anode ear described in this practicality and negative electrode lug along battery Width between spacing (distance namely between the center line of anode ear broad ways and the center line of the negative electrode lug Width) 3/5-4/5 that is positive plate Breadth Maximum.More preferably 4/5; Adopt the contact that this structure can prevent therebetween further, reduce short-circuit risks.
The winding of battery core of the present invention and the assembling of whole battery are flexible-packed battery industry routine techniques means, do not repeat them here.And in order to graph expression clear, barrier film is not illustrated out.
