Description
Technical field:
The present invention relates to a kind of high power charging battery manufacture process, be specifically related to a kind of high power nickel-hydrogen charging battery manufacture process.
Background technology:
Entered since 21st century, along with the unprecedented attention of the mankind to environmental protection and energy crisis, greatly promoted the demand in environmental protection rechargeable battery market, meanwhile, raising along with social modernization's level, people are also more and more higher to the performance requirement of rechargeable battery, be embodied in the output to rechargeable battery power, the requirement that adapts to electric tool just must reduce the internal resistance of rechargeable battery, realize the heavy-current discharge of rechargeable battery, for realizing this performance, prior art mainly contains following several method: both positive and negative polarity carries out the face weldering with the nickel sheet; Both positive and negative polarity carries out afflux with a plurality of lugs; Anodal employing face weldering, negative pole carries out spot welding etc. with wire netting.But above method all will be used negative pole face weldering or point in the box hat bottom, and the negative pole effect of confluxing is all undesirable, and contact resistance is big, generate heat during work, and just increased making workload and production cost, even destroy the outward appearance of battery, influence the security performance and the power output of battery.
Summary of the invention:
Technical problem to be solved by this invention is: solve the problem that above-mentioned prior art exists, and provide a kind of by to the improvement of the optimization of the selection of active material, positive and negative afflux structure, utmost point group structure, realize that internal resistance is little, specific power is high, satisfy the high power charging battery manufacture process that high-rate battery discharge requires.
The technical solution used in the present invention is: this high power charging battery manufacture process, comprise positive pole, negative pole, barrier film, just, negative pole is filled active material, in the box hat and inject electrolyte, positive pole adopts nickel foam to make basis material in manufacturing process, the anode collection structure is by anodal matrix nickel foam, the afflux dish connects and composes on nickel plating or the pure nickel, negative pole adopts expanded metal to make basis material, end spot welding burr nickel plating with holes sheet next part flow table in the box hat, place nickel foam or foam copper pad on the next part flow table, negative pole presses down and pad, the next part flow table, box hat connects and composes the negative pole currect collecting structure.
In the technique scheme, anodal top is left the nickel foam of certain width and is not filled active material, and negative pole bottom is a toothed edge.
In the technique scheme, when positive pole, barrier film, negative pole coiling, positive and negative electrode staggers, and has the active material face to carry out corresponding separating with barrier film.
In the technique scheme, the positive and negative electrode Capacity Ratio is 1: 1.3～2.1.
In the technique scheme, positive active material comprises anode additive, anodal spherical hickelous nydroxide, and negative electrode active material comprises negative alloy powder.
In the technique scheme, anode additive is Y

The present invention sums up following 2 points:
1, improves structure
Traditional power type Ni-MH battery generally has two kinds of structures, a kind of is multipole ear, a kind of is the end face weldering, experimental results show that, the internal resistance and the specific power of end face weldering battery are better than multipole ear mode, and end face weldering battery is divided into two kinds, and a kind of is the weldering of negative pole end face, anodal multipole ear, and another kind is that both positive and negative polarity all adopts the end face weldering.No matter be any, the bus structure of its negative pole is all undesirable, even because adopt the negative pole of end face weldering, though its end face welds finely, but on can only being welded at the bottom of the box hat by an elongated capillary point with the contact site of box hat, thereby be difficult to guarantee the good condition of confluxing, because of contact resistance generates heat just unavoidable greatly.Super high power Ni-MH battery of the present invention adopts unique bus structure, and positive/negative plate all directly contacts with anodal (top cover), negative pole (at the bottom of the box hat) with end pattern, thereby the internal resistance that guarantees battery is enough little.
2, rational formula
In order to improve discharge platform, increase specific power, to improve battery high-temperature behavior, we adopt the high-power Ni (OH) of high temperature power alloyed powder (as golden peak flying height temperature power alloyed powder or tall building tungsten high temperature power alloyed powder etc.) and high-quality
2Powder is (as Cologne, Henan or the long excellent power-type Ni (OH) in Jiangmen
2Powder etc.), add an amount of conduction (as inferior cobalt or nickel powder etc.) simultaneously, battery high-temperature behavior and discharge platform are of great benefit to.Through a large amount of tests, we have selected the good barrier film of rational potassium, sodium, lithium ternary electrolyte prescription and gas permeability (as Mitsubishi, NKK, German FS series, Britain SciMaT series etc.) in addition.Facts have proved this type of prescription, the high 40-60mV of 10C discharge meta voltage ratio regular convention formula.
Therefore, structure optimization of the present invention is made simply, satisfies the high-rate battery discharge requirement, and internal resistance is little, and the specific power height has improved battery high-temperature behavior, and battery safety is good, the power output height.
