Description
Technical field:
The utility model relates to a kind of high power charging battery, is specifically related to a kind of high power nickel-hydrogen rechargeable battery.
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 in the utility model is: solve the problem that above-mentioned prior art exists, and provide a kind of by to the improvement of the optimization of positive and negative afflux structure, utmost point group structure, realize that internal resistance is little, specific power is high, improve battery high-temperature behavior, satisfy the high power charging battery that high-rate battery discharge requires.
The technical solution adopted in the utility model is: this high power charging battery, comprise positive pole, negative pole, barrier film, positive and negative electrode is filled active material, in the box hat and inject electrolyte, the anode collection structure is connected and composed by afflux dish on anodal matrix nickel foam, nickel plating or the pure nickel, the negative pole matrix is an expanded metal, 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 with pad, next part flow table, box hat and 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.
The utility model is summed up, it is to improve structure at all: 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 structure, 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; 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, have just can hardly be avoided because of contact resistance generate heat greatly.Super high power Ni-MH battery of the present utility model 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.The utility model is also by the selection to active material, and rational formula improves discharge platform, increases specific power, improves battery high-temperature behavior.
Therefore, the utility model structure optimization is made simply, satisfies the high-rate battery discharge requirement, and internal resistance is little, and security performance is good, the power output height.
