Background technology
Along with the development of cordless power tool, wireless household electrical appliances, electric automobile and wind, photoelectromotive force, particularly increasing to the demand of lithium dynamical battery to the battery of power type, accumulation energy type, lithium battery large-capacity high-power performance more and more receives publicity.But all the time, because the rising property of gas etc. under the activity of anode material of lithium battery, high temperature brings certain potential safety hazard to lithium battery, manufacturing and user are general in the security concern for lithium battery, and are the various blast resistance constructions that the strick precaution of security devises such as vent valve, rupture pressure disc etc.
Single punching type with regard to current rupture pressure disc employing or Laser Welding direct type, punching type is because of the error of its equipment and mold precision, and the thickness became uneven of punching membrane, bears pressure uneven, uniformity extreme difference; Laser Welding direct type is because of complex process, and equipment investment is large, the variety of problems such as operating cost is high, and under welding unstable situation, scrappage is also high simultaneously, also there is mechanization, automation not easily realizes, and production efficiency is low.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of manufacture craft is simple, and equipment investment is few, and operating cost is low, good product consistency, the explosion-proof aluminium aluminium composite material of aluminum-shell battery that explosion-proof uniformity is effective and manufacture method thereof and application thereof.
In order to solve the problems of the technologies described above, the explosion-proof aluminium aluminium composite material of aluminum-shell battery of the present invention, comprise the thicker aluminum base plate of thickness (base material), aluminum base plate has the relief hole that several are formed by stamping-out mode, aluminum base plate has the aluminium foil adopting cold rolling forging conjunction mode compound, after aluminum base plate and aluminium foil compound, make the aluminium foil place of relief hole position form one deck pressure release film.
Described aluminum base plate and aluminium foil have same profile size.
A manufacture method for the explosion-proof aluminium aluminium composite material of aluminum-shell battery, comprises the following steps:
A, the soft state aluminium sheet first adopting thickness thicker are substrate;
B, on substrate the some relief holes of equidistant punching;
The aluminium foil of C, employing thinner thickness and substrate are stacked and adopt cold rolling forging conjunction mode continuous rolling compound.
An application for the explosion-proof aluminium aluminium composite material of above-mentioned aluminum-shell battery, is used for making battery cover board of aluminum shell by above-mentioned aluminium aluminium composite material.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the explosion-proof aluminium aluminium composite material of aluminum-shell battery of the present invention and manufacture method thereof and application thereof are described in further detail.
As shown in the figure, the explosion-proof aluminium aluminium composite material of aluminum-shell battery of the present invention, comprise the thicker aluminum base plate of thickness 1, aluminum base plate 1 has the relief hole 2 that several are formed by stamping-out mode, aluminum base plate 1 has the aluminium foil 3 adopting cold rolling forging conjunction mode compound, aluminum base plate 1 and aluminium foil 3 have same profile size, make the aluminium foil place of relief hole 2 position form one deck pressure release film after aluminum base plate 1 and aluminium foil 3 compound.
A manufacture method for the explosion-proof aluminium aluminium composite material of aluminum-shell battery, is characterized in that, comprise the following steps:
A, the soft state aluminium sheet first adopting thickness thicker are substrate;
B, on substrate the some relief holes of equidistant punching;
The aluminium foil of C, employing thinner thickness and substrate are stacked and adopt cold rolling forging conjunction mode continuous rolling compound.
Such as, for 38130 type aluminum shell column type lithium ion battery explosion-proof lids, concrete steps are as follows:
1, first adopt thickness be 3.5mm, width is 40mm, the trade mark be 3003 soft state aluminium sheet be base material;
2, be the hole that equidistant punching is about 7mm in the longitudinal direction of base material by 40mm, after rolling hole be 6mm;
3, adopt width to be 40mm, thickness is that the aluminium foil of 0.1mm and base material are stacked continuous rolling compound;
4, the material film body uniformity after compound is good, is adopted flushing technology to be processed into explosion-proof covering board;
5, surveying its hole, to bear gas pressure be 12KG.
As can be seen here, the present invention is by the substrate clad aluminum foil (film material) after punching, first the making of this material presses the good explosion-proof hole of required interval punching on substrate band, the film material of aperture calculation of pressure and thickness setting is pressed again at its surface attachment one deck, the product finally made, material uniformity is good, and explosion-proof pressure uniformity is good, and the performance of lithium dynamical battery can be made to be greatly improved.
The application of the explosion-proof aluminium aluminium composite material of above-mentioned aluminum-shell battery in the present invention, both can be used for making battery cover board of aluminum shell by above-mentioned aluminium aluminium composite material, also above-mentioned aluminium aluminium composite material can be used for making aluminum-shell battery housing.
In embodiment, as shown in Figure 1-Figure 3, the compacting deflection first pressing aluminium sheet cold forging pressure selects base material 1, refers again to and needs the size interval punching of processing work to reserve explosionproof hole position 2, the compacting deflection pressing aluminium film cold forging pressure is again selected to paste aluminium film 3 again, becomes a useful person through cold rolling compounding machine compound.
