Description
Technical field
The technical field of big cylindrical lithium battery is the utility model is related to, more particularly to a kind of new collector plate of lithium battery.
Background technology
Lithium battery because its long lifespan, it is environmentally friendly many advantages, such as, have become the sophisticated industry in energy storage field, it is widely used in
The important industry such as electric automobile, energy storage device.By development for many years, with the raising gradually of quality and technique, the longevity of battery
Life obtains very high lifting with durability, and is proved by long-term operation, the overall quantity of operation of lithium battery, not only with list
The quality of body battery is related, and the packaging technology, structure more with lithium battery in groups are closely bound up, and the collector plate on lithium battery is same
The quality for affecting lithium battery of many degree；As shown in Figure 4 and Figure 5, it is existing collector plate, existing collector plate is circle
Shape, its circle show six pressure ditches 7 and six long waist shaped holes 8, the pressure ditch 7 and the interphase distribution of long waist shaped hole 8, and institute
The neighboring for stating collector plate is provided with six sections of flange 9, and for the welding with connecting plate 10, and the collector plate has following lack at present
Fall into：
1st, six sections of flange 9 of collector plate easy sideslip of size in punching production, cause have gap, serious shadow with connecting plate 10
Ring laser welding,
2nd, flange type shape needs exceptionally to justify six sections of sharp welding, easily causes weldering quarrel and is splashed to inside battery, causes battery core short
Road,
3rd, stamping procedure is more, assembles difficult cost height, unfavorable large-scale production.
Utility model content
Technical problem to be solved in the utility model is overcome the deficiencies in the prior art, there is provided it is a kind of it is simple in construction,
The high lithium battery new collector plate low with production cost of production efficiency.
Technical scheme is used by the utility model：The utility model includes collector plate body, the collector plate body
Center section be provided with pole, circle shows several stamped grooves and some groups of circular hole groups on the collector plate body,
The number of the circular hole group is equal with the number of the stamped grooves, and the stamped grooves and the circular hole group are in alternate point
Cloth, the circular hole group is provided with several circular holes, and the circular hole described in every group in circular hole group is arranged in collection described in same
Flowing plate body is from the outside ray in center.
Further, the profile of the pole is cylindric, and the center of the pole is provided with screwed hole.
Further, the profile of the collector plate body is circle, the collector plate body be by aluminium alloy or copper into.
Further, the outer surface of the collector plate body is smooth surface or is provided with electroless nickel layer.
Further, the collector plate body and the pole are fixedly connected by welding in one.
Further, the number of the stamped grooves is four or five or six, and the group number of the circular hole group is four groups
Or five groups or six groups, the circular hole number of circular hole group described in every group is two.
The beneficial effects of the utility model are：Because the utility model includes collector plate body, the collector plate body
Center section is provided with pole, and circle shows several stamped grooves and some groups of circular hole groups, institute on the collector plate body
It is equal with the number of the stamped grooves to state the number of circular hole group, and the stamped grooves and the circular hole group are in distribute alternately,
The circular hole group is provided with several circular holes, and the circular hole described in every group in circular hole group is arranged in collector plate described in same
Body is from the outside ray in center, so the utility model is simple in construction, the collector plate body can with one time punching molded,
And the pole can be welded directly with battery cover board, make the utility model relative to existing afflux harden structure it is simpler, can
With the requirement for reducing stamping procedure, reducing production technology, make its production efficiency higher, save production cost.
