Abstract
The utility model discloses a stainless steel band with single-side coated by nickel, which is used for the shell and the cover of a button-type lithium-ion battery and comprises a base material and a plated metal nickel coating. The base material is stainless steel, metal nickel is plated on one surface of the stainless steel base material, and the other surface thereof is rough. The stainless steel band has the advantages of simple process, reasonable structure, low production cost, excellent welding property, conductivity and corrosion resistance, higher intensity and rigidity, and applicability to industrial production. The stainless steel band is a better shell material which can substitute for the prior lithium-ion power battery, and is especially suitable for being used as the shell and cover of the high performance lithium-ion battery.
Description
Technical field
The utility model relates to buckle type lithium-ion battery case, cover material, is meant that especially a kind of single face that is used for buckle type lithium-ion battery case, lid covers the nickel and stainless steel band.Belong to the sheet metal strip surface treatment technology.
Background technology
Buckle type lithium-ion battery case, cover material require it to have good soldering performance, excellent conducting performance and excellent decay resistance and certain intensity, hardness, to satisfy the requirement of its operational environment; Existing buckle type lithium-ion battery case, cover material adopt ferritic stainless steel band (as SUS 430) or austenic stainless steel belt (as SUS 304) punch forming usually.Adopt the buckle type lithium-ion battery of ferritic stainless steel band punching press shell, lid, electric conductivity, welding performance and scratch resistance performance are relatively poor; Adopt the buckle type lithium-ion battery of austenic stainless steel belt punching press shell, lid, except that having above-mentioned deficiency, also have the higher weak point of production cost.
Summary of the invention
The purpose of this utility model be to overcome the deficiency of prior art and provide a kind of production technology simple, rational in infrastructure, have good welding performance, electric conductivity, decay resistance and higher intensity, the single face that is used for buckle type lithium-ion battery case, lid of hardness and cover the nickel and stainless steel band.
The utility model is to adopt following proposal to realize: comprise basis material and plated metal nickel dam, described basis material is a stainless steel, and at a plated metal nickel of described stainless steel base material, another side is coarse surface.
In the utility model, the thickness of described metal nickel dam is the 0.1-3.0 micron, is preferably the 0.5-2.5 micron.
In the utility model, described metal nickel dam Wei Shi hardness is more than or equal to 300 (HV).
In the utility model, the surface roughness Ra of the another side of described stainless steel band 〉=0.4.
In the utility model, described basis material is the ferritic chromium steel band.
The utility model is owing to adopt said structure, one side plating one deck and metallic tin contact angle at stainless steel base are little, soak into good metal nickel, having improved the utility model effectively--the soldering that-single face covers the nickel and stainless steel band connects performance, thereby, improve obviously that stainless steel is difficult to be soaked into by tin and its soldering of causing connects the drawback of poor performance; Because in the stainless steel alloy structure, the random distribution of interstitial atom or solid solution atom causes the lattice mismatch and the lattice defect of matrix easily, thereby has reduced the movement velocity of electronics in atomic lattice, its electric conductivity is lower; And the crystal structure of metallic nickel evenly distributes, and its lattice mismatch and lattice defect are considerably less, therefore, more helps to improve the electric conductivity of finished product battery in the nickel plating of stainless steel band single face, promptly reduces the resistance of battery; Because the corrosion potential of nickel coating is greater than the stainless steel-based end, therefore, the decay resistance after the nickel plating of stainless steel band single face obviously is better than the matrix stainless steel.In addition, because the Wei Shi hardness of described nickel coating is more than or equal to 300 (HV), therefore, its surperficial scratch resistance ability is improved significantly; Particularly in actual production process, stainless steel band need become battery case through the punching out of multiple working procedure ability, experienced a series of stretch bending deformation process, in this process, owing to reasons such as dislocation, lattice distortions, to intensity, the hardness of material obviously be improved, therefore, bulk strength, hardness and scratch resistance ability that single face covers the nickel and stainless steel band be can satisfy arts demand fully.In sum, the utility model production technology is simple, rational in infrastructure, production cost is low, have good welding performance, electric conductivity, decay resistance and higher intensity, hardness.Being suitable for suitability for industrialized production, is a kind of sheathing material of more excellent, alternative existing lithium ion battery, is specially adapted to high performance lithium ion battery lid and shell.
