Abstract
The utility model discloses a cylinder type lithium ion battery with compound area utmost point ear of aluminium - nickel has the negative pole piece, a serial communication port, the negative pole piece is equipped with the compound area utmost point ear of aluminium - nickel, the compound area utmost point ear of aluminium - nickel including the welding on the negative pole piece the aluminium strip and through the welding point with the nickel strap that aluminium strip tip welding is in the same place. The processing procedure process is, stay white department to the welding of partly aluminium strip at the negative pole piece earlier, then weld the convex aluminium strip of another part with ultrasonic bonding controller for the nickel strap and be in the same place, alright make a neotype utmost point ear. The utility model discloses the beneficial effect who has: the loss is low, and the rosin joint is few, and the battery of making in addition all has more obvious advantage in the aspect of internal resistance and 1C charge -discharge cycle to the effectual processing performance that improves the new product.
Description
Technical field
The utility model relates to lithium ion battery correlative technology field, is specifically related to a kind of cylindrical lithium ion battery with aluminium-nickel composite band lug.
Background technology
Along with the development of microelectric technique, miniaturized equipment is increasing, has higher requirement to power supply.All many-sided remarkable performances such as lithium battery is high by feat of its energy density, charge efficiency is high, output voltage is high, possess high power endurance, self-discharge rate is low, quality is little, Acclimation temperature type strong, environmental protection are widely used in a lot of aspect by people, such as mobile phone, palmtop PC, electric motor car, street lamp stand-by power supply, family expenses small electric apparatus is even in military equipment and Aero-Space.Meanwhile, lithium battery is also referred to as " having the chemical power source of application future most " by people.
And cylindrical battery is as the important plate of in whole lithium electrical travelling industry, because it has stable and jumbo characteristic, play an important role in instrument back-up source, the dark favor by vast lithium battery user.Meanwhile, also in order to allow to extend the useful life of electrical appliance, the cylindrical battery that this just requires us to produce ensures the consistency in combo process, and not only voltage is consistent, also wants internal resistance and capacity to be close.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, provides a kind of cylindrical lithium ion battery with aluminium-nickel composite band lug improving discharge capacity of the cell.
In order to reach the purpose of this utility model, technical scheme is as follows:
A kind of cylindrical lithium ion battery with aluminium-nickel composite band lug, there is negative plate, it is characterized in that, described negative plate is provided with aluminium-nickel composite band lug, and described aluminium-nickel composite band lug comprises and is welded on aluminium strip on negative plate and by the nickel strap of pad together with described aluminium strip welding edges.
Preferably, described pad is positioned at the outside of described negative plate.
Preferably, the length of described aluminium strip is 70% ~ 80% of described aluminium-nickel composite band total length.
Preferably, a described aluminium strip part is welded on described negative plate, and another part protrudes outside negative plate.
Preferably, the length of described nickel strap is greater than the radius of battery.
Processing procedure process is, first a part of aluminium strip (length accounts for 70% of whole lug) is welded on negative plate blank space, then the aluminium strip (length accounts for 10% of whole lug) of another part protrusion and nickel strap ultrasonic bonding controller are welded together, just can make a kind of novel lug.
The beneficial effect that the utility model has:
1. aluminium-nickel strap lug is few compared with the cost of the battery that nickel strap lug makes, and lug loss is low;
2. can make cell voltage, internal resistance and capacity in a relative consistent scope, thus can make the cost performance of battery be improved.
3. the battery made by: (a) multiplying power is tested: 2C discharge capacitance aluminium-nickel lug is 95% good compared with 92% of nickel lug; (b) internal resistance: aluminium-nickel lug is that 35-38 milliohm is low compared with the 40-45 milliohm of nickel lug; (c) 1C charge/discharge: 300 the capability retention aluminium-nickel lugs that circulate can reach 80% apparently higher than 65% of nickel lug;
4. make of aluminium-nickel strap lug and easily to weld with pole piece and rosin joint is less, effectively raise the processing performance of product.
Accompanying drawing explanation
Fig. 1 is the Facad structure schematic diagram of the utility model negative plate;
Fig. 2 is the structural representation that the utility model has the cylindrical lithium ion battery of aluminium-nickel composite band lug.
Embodiment
Below in conjunction with embodiment, the utility model is further described, but protection range of the present utility model is not only confined to embodiment.
As shown in Figure 1, a kind of cylindrical lithium ion battery with aluminium-nickel composite band lug, comprises positive plate, negative plate 5, diaphragm paper, anode ear, aluminium-nickel composite band lug, lower gasket 6.
Be provided with aluminium-nickel composite band lug at negative plate 5, described aluminium-nickel composite band lug comprises and is welded on aluminium strip 1 on negative plate 5 and by the nickel strap 3 of pad 2 together with described aluminium strip 1 welding edges.
Pad 2 is positioned at the outside of described negative plate 5, and namely the length of aluminium strip 1 is the width being greater than negative plate 5.The length of aluminium strip 1 accounts for 70% ~ 80% of aluminium-nickel composite band total length.
Shown in composition graphs 2, first, length is about the aluminium strip 1 of 43mm, negative plate 5 lug end is welded on supersonic welder, then get the nickel strap 3 being about 10mm, finally aluminium strip 1 and nickel strap 3 are welded together with supersonic welding machine controller, pad 2 length used is about 3mm.But the length of nickel strap 3 is greater than the radius of battery, the length of nickel strap 3 therefore used when welding must cover the centre bore 4 of lower gasket 6 completely, is convenient to the contact that back welding increases battery core and box hat.
Last it is noted that above embodiment only in order to illustrate the utility model and and technical scheme described by unrestricted the utility model, therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment, but, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, and all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
