Abstract
The utility model discloses an edge fold nickel net. The edge fold nickel net comprises a nickel net, wherein the nickel net is in a long strip shape; two long edges of the nickel net are bent inwards along the direction of a short edge of the nickel net to form edge fold; the width of each edge fold is 1.5-2.5mm. According to the edge fold nickel net, the possibility of generating burrs in the manufacturing process of a positive pole of a power type lithium sub-battery can be avoided and the possibility of short circuit caused by directly contacting the positive pole and a negative pole due to the reason that the burrs pierce a membrane is reduced, so that the safety performance of the power type lithium sub-battery is greatly improved.
Description
Technical field
The utility model belongs to the sub-battery technology of power-type lithium field, is specifically related to a kind of flanging nickel screen.
Background technology
At present, known disposable lithium-battery, due to its superior large electric current, high power and good property at high and low temperature, is more and more subject to vast producer and client's welcome.In traditional positive electrode manufacture process, be nickel screen with holes or the nickel screen using, and nickel hole pattern unavoidably can produce some burrs in cutting process, and this very sharp just of the edge of nickel screen, in the manufacturing process of battery, will cause like this burr to pierce through barrier film, both positive and negative polarity is connected, causes the problem of battery short circuit.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of flanging nickel screen, it can avoid the sub-anode probability that burr produces in manufacture process of power-type lithium, cause the directly possibility of contact short circuit of both positive and negative polarity thereby reduce because burr pierces through barrier film, greatly improved the security performance of the sub-battery of power-type lithium.
The utility model solves the technical scheme that its technical problem adopts: flanging nickel screen, comprise nickel screen, described nickel screen be shaped as strip, 2 long limits of described nickel screen form flanging along the inside bending of short side direction of described nickel screen respectively, the width of described flanging is 1.5-2.5mm.
By technique scheme, the width of described flanging is 2mm.
By technique scheme, the thickness of described nickel screen is 0.13mm, and width is 35mm.
The utility model, there is following beneficial effect: by by the inside bending in long limit of nickel screen, make nickel screen marginal portion no longer sharp, avoid the sub-anode probability that burr produces in manufacture process of power-type lithium, cause the directly possibility of contact short circuit of both positive and negative polarity thereby reduced because burr pierces through barrier film, greatly improved the security performance of the sub-battery of power-type lithium.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the vertical view of Fig. 1.
Wherein, 1-nickel screen, 2-flanging.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
In preferred embodiment of the present utility model, as shown in Figure 1, flanging nickel screen, comprises nickel screen 1, nickel screen 1 be shaped as strip, the thickness of nickel screen is 0.13mm, width is 35mm, and 2 long limits of nickel screen 1 form flanging 2 along the inside bending of short side direction of nickel screen 1 respectively, and the width of flanging 2 is 1.5-2.5mm, being originally in embodiment, the width of flanging 2 is 2mm.
As shown in Figure 2, first nickel screen is carried out to flanging processing, then carry out positive electrode making according to process, because the nickel screen marginal portion of flanging is no longer sharp, can reduces owing to piercing through barrier film and make the connected phenomenon that causes battery short circuit of both positive and negative polarity.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection range of the utility model claims.
Claims (3)
