Abstract
The invention discloses a machining method for a conductive composite metal sheet between lugs in batteries or the batteries. According to the conductive composite metal sheet located between the lugs in the batteries or the batteries and produced through the method, the thickness of a nickel metal layer on the surface of the metal sheet is much larger than the thickness of an electroplated coating, so that the welding strength is high, the welding difficulty is low, and a cold solder joint is not prone to being generated; and the binding strength between the nickel metal layer and a copper belt is higher, and the performance of a whole battery set is ensured. The method is characterized by comprising the following steps of conducting grooving and tailoring on a copper belt and a nickel belt, conducting cleaning and oil removal on the copper belt and the nickel belt, conducting annealing on the copper belt and the nickel belt, polishing of the surfaces of the copper belt and the nickel belt, compositing, annealing and cold rolling finally.
Description
Technical field
The present invention relates to conducting composite metal sheet and processing method between the lug of inside battery or battery.
Background technology
Background technology, in secondary cell and other electron trade, uses spot-welding technology all in a large number.And traditional soldering and need with the solder technology of solder most by spot welding substitute because slicker solder dust need can be produced with solder in welding process, contaminated environment and also weld strength inadequate, it is difficult to scrap rear material processed, easily contaminated environment again.The lug of existing inside battery and conductive metal sheet between batteries generally adopt pure nickel or nickel-plated steel, because the enclosure material of battery is generally nickel-plated steel, the better performances connected with spot welding between two parts that material is identical, but pure nickel is expensive and nickel-plated steel gets rusty easily; Copper strips is selected in present industry research, and copper strips resistance is little, relative low price, but the spot welding characteristics of copper and nickel plating box hat is bad.So industry research is at employing copper nickel composite material band, concrete processing method is shown in the patent application document of application number 200510038116.5.Conductive metal sheet between the lug of the inside battery adopting this technique to make or battery, copper nickel composite band is adopted to replace original pure nickel band, with other Metal Phase ratio, there is good spot weldability, but after copper nickel compound, high to welding requirements, easy generation rosin joint, therefore can have influence on the performance of whole battery pack; In addition, copper strips and nickel strap, at compound tense, are slightly slipped to the cleaning treatment of material, just have skin effect phenomenon and occur, and like this in combination process, the alloy-layer bond strength formed between nickel and copper molecule is inadequate, can have influence on the performance of battery in follow-up use.
Summary of the invention
Conducting composite metal sheet between the lug of the inside battery made for existing processing technology or battery, after copper nickel compound, high to welding requirements, easily produce rosin joint, thus whole battery performance can be had influence on; In addition, the cleaning treatment of material is slightly slipped, the alloy-layer bond strength formed between nickel and copper molecule is inadequate, also can have influence on the shortcoming of battery performance in follow-up use.
The invention provides the another kind of processing method of conducting composite metal sheet between the lug of inside battery or battery, conducting composite metal sheet between the lug of the inside battery produced by the method or battery, welding difficulty needed for it reduces greatly, not easily produce rosin joint, solder skip, reduce the scrappage of product; And the bond strength of nickel metal layer and copper strips is high, guarantee the performance of whole battery pack.
Its technical scheme is: it is characterized in that: it comprises the following steps:
(1), fluting, cutting
The employing trade mark is the nickel strap of the copper strips of TP1, TP2, TU1 or TU2, purity 99.5%, offers dark 0.01umm-1um together, the groove of wide 1cm--10cm in the middle of nickel strap, and the groove of the corresponding nickel strap of copper strips is wide carries out cutting;
(2), to cleaning, the oil removing of copper strips, nickel strap
Copper strips and nickel strap degreaser clean;
(3), copper strips, nickel strap are annealed
Copper strips, nickel strap are heated to 600 DEG C-800 DEG C, naturally cool;
(4), oxide layer process is carried out to the surface of copper strips, nickel strap
With the polissoir of wire wheel manufacture with water polishing is cleaned to copper strips, nickel strap;
(5), inlay, compound
Copper strips is inlaid in the groove of nickel strap, compound on composite rolling mill;
(6), anneal
Step (5) is made composite band be heated to 750 DEG C-850 DEG C, naturally cool;
(7), the composite band processed through step (6) is cold-rolled to desired thickness.
Described composite metal can be two-sided compound.
The copper nickel composite band adopting above-mentioned technique to make, the thickness of its surface nickel belt can pre-set as requested, and its thickness is much larger than the thickness of galvanization coating, and the intensity of spot welding is high; Nickel by original plating instead by inlaying, cold rolling directly and copper strips compound, like this copper strips surface distributed be nickel foil, completely isolated with the air in the external world, copper strips can not get rusty, and owing to adopting the method for first inlaying rear compound, thus avoids the copper nickel strap of existing technique making, because coating is thinner, spot welding intensity difference, easily produces rosin joint, thus can have influence on the shortcoming of whole battery performance.
