Description
Technical field
The utility model relates to a kind of modular construction of lithium electricity, and specifically a kind of lithium electricity end face weldering collector, belongs to electric energy storage device technical field.
Background technology
Along with economic and social development, battery particularly lithium battery all just at high speed development.Lithium battery, due to its high-energy-density, long-life, environmental protection, is more and more subject to people's attention, and lithium electricity battery will have a extensive future aspect electric vehicle power sources and accumulation power supply.Insider generally believes: the battery of low capacity adopts column type explained hereafter, and the battery of high power capacity adopts square laminate patch explained hereafter.Key issue is also in afflux problem in fact.Because what the pole piece positive and negative electrode skeleton of lithium battery adopted respectively is very thin Copper Foil and aluminium foil, cannot directly adopt end face weldering.So up to the present, general cylindrical lithium battery all adopts monopole ear afflux, and the lithium battery of power type adopts multi pole ears afflux., there is square laminated type technique in the lithium dynamical battery of high power, ultra-high capacity afterwards.
Although adopt roll welding lug to solve some problems, positive and negative electrode very Multilayer pole ear is more difficult.In the time that prior art is assembled, not only efficiency is low, and battery quality is not high yet.End face welding technology also has application on the motive-power battery such as SC on Ni-MH battery, nickel-cadmium cell, but its end face weldering collector is to have burr in one side, in the time that end face welds, these burrs can insert respectively in battery core both positive and negative polarity edge, and also will weld the preceding paragraph lug on plus plate current-collecting body.Very thin Copper Foil and aluminium foil that the pole piece positive and negative electrode skeleton of lithium battery adopts respectively, cannot use alkaline battery end face weldering collector.
Summary of the invention
The utility model is for the problems referred to above, a kind of lithium electricity end face weldering collector is provided, adopt the pole piece positive and negative electrode skeleton of the lithium battery of this collector can directly carry out end face weldering, be applicable to large capacity, high-power cylinder type lithium battery, its technical scheme adopting is as follows:
A kind of lithium electricity end face weldering collector, comprise flow guiding disc, on flow guiding disc, offer centre bore, three welding grooves of arranging with equal intervals that flow guiding disc radial surface is provided with, flow guiding disc surface is divided into more than three quadrant by welding groove, in one of them quadrant, be provided with conduction lug, conduction lug is connected with flow guiding disc one, in all the other quadrants, offers delivery hole.
Described flow guiding disc radial surface is provided with four welding grooves of equidistantly arranging, flow guiding disc surface is divided into four quadrants by described welding groove, in one of them quadrant, be provided with conduction lug, described conduction lug is connected with flow guiding disc one, in its excess-three quadrant, offers delivery hole.
Described delivery hole is isosceles right triangle shape, and leg-of-mutton right angle fixed point is pointed to flow guiding disc center.
The rectangular shape of described conduction lug, the edge of flow guiding disc is stretched out in conduction lug outside.
The utility model has the advantage of:
The utility model provides a kind of brand-new lithium electricity end face weldering collector, this product manufacture is simple, in use, catchment effect is good, greatly reduce the Ohmic resistance of battery, the performance of lithium battery is largely increased, and the utility model also contributes to the automated production of high power, the assembling of ultra-high capacity cylinder lithium dynamical battery simultaneously.
