Abstract
The invention relates to a method for processing the electrode ear inside the battery or the conductive metallic plates between batteries. The inventive electrode ear or the conductive metallic plate has larger surface nickel metal layer thickness than the plated one, and high strength of point welding without rosin, while the high connection strength between the nickel metal layer and the copper band can confirm the property of battery. It is characterized in following steps: washing, removing oil, annealing the copper band and nickel band; polishing the surface of two bands; compounding, annealing and cold rolling.
Description
(1) technical field
The present invention relates to the processing method of the lug or the conductive metal sheet between batteries of inside battery.
(2) background technology
In secondary cell and other electron trade, all use spot-welding technology in a large number.And traditional soldering and need to be substituted by spot welding with the solder technology majority of scolder because need with scolder in welding process, can produce the slicker solder dust, contaminated environment and weld strength are not enough, material processed difficulty after scrapping, contaminated environment once more easily.The lug and the conductive metal sheet between batteries of existing inside battery generally adopt pure nickel or nickel-plated steel, because the enclosure material of battery is pure nickel or nickel-plated steel, the better performances that connects with spot welding between the identical two parts of material, nickel-plated steel gets rusty easily but pure nickel costs an arm and a leg; Copper strips is selected in industry research now for use, and copper strips resistance is little, relative low price, but the spot welding characteristics of copper and nickel plating box hat, pure nickel is bad.So industry research is at the surface of copper strips plating layer of metal nickel, concrete processing method is seen the patent application document of application number 200410041400.3.Adopt the lug of the inside battery that this technology makes or the conductive metal sheet between the battery, its surface is the coating of nickel, compares with other metal to have spot weldability preferably, but because coating is thinner, the spot welding intensity difference is easy to generate rosin joint, therefore can have influence on the performance of whole battery group; In addition, only simple connection between nickel molecule and the copper strips during plating, processing has careless omission slightly to cleaning of materials, just having skin effect phenomenon takes place, like this in combination process, the alloy-layer bond strength that interpenetrates formation between nickel and the copper molecule is not enough, can have influence on the performance of battery in follow-up use.
(3) summary of the invention
At the lug or the conductive metal sheet between batteries of the inside battery that has the processing technology making now, because coating is thinner, the spot welding intensity difference is easy to generate rosin joint, thereby can have influence on the whole battery group performance; In addition, processing has careless omission slightly to cleaning of materials, and the alloy-layer bond strength that interpenetrates formation between nickel and the copper molecule is not enough, also can have influence on the shortcoming of battery performance in follow-up use.The invention provides the another kind of processing method of the lug or the conductive metal sheet between batteries of inside battery, the lug or the conductive metal sheet between batteries of the inside battery of producing by this method, its surperficial nickel metal layer thickness is much larger than the thickness of coating of electroplating, the intensity height of spot welding is difficult for producing rosin joint; And the bond strength height of nickel metal layer and copper strips is guaranteed the performance of whole battery group.
Its technical scheme is such: it is characterized in that: it may further comprise the steps,
The cleaning of a, copper strips and nickel strap, oil removing
The employing trade mark is the copper strips of TP1, TP2, TU1 or TU2, and purity is 99.5% nickel strap, and the thickness of copper strips and nickel strap cleaned with degreaser than 1: 4;
B, copper strips, nickel strap are annealed
Copper strips, nickel strap are heated to 600-800 degree centigrade, natural cooling;
C, the surface of copper strips, nickel strap is polished respectively
Polissoir with the wire wheel manufacturing is cleaned polishing with water to copper strips, nickel strap;
D, compound
Copper strips, nickel strap is compound on composite rolling mill;
E, annealing
Composite band is heated to 750-850 degree centigrade, natural cooling;
G, cold rolling
The complex copper nickel strap is cold-rolled to desired thickness.
The copper nickel composite band that adopts above-mentioned technology to make, the thickness of its surface nickel belt can set in advance as requested, and its thickness is much larger than the thickness of galvanization coating, the intensity height of spot welding; Nickel is changed into the surface that directly is compounded in copper strips by cold rolling by original plating, be nickel foil in the surface distributed of copper strips like this, isolated fully with the air in the external world, copper strips can not get rusty, owing to adopt cold rolling, the alloy-layer bond strength height that the aspect that combines between copper strips and the nickel forms, thereby the copper nickel strap of having avoided existing technology to make, because coating is thinner, the spot welding intensity difference, be easy to generate rosin joint, thereby can have influence on the shortcoming of whole battery group performance.
