Abstract
The utility model discloses a lithium ion battery anode tab, which comprises an aluminum tape and tab adhesive bonded on the aluminum tape, wherein the aluminum tape is further welded with a nickel strap, and a distance from a welded center portion of the aluminum tape and the nickel strap to a center position of the tab adhesive is smaller than or equal to 20mm. By aid of the anode tab with the structure, an aluminum-to-nickel process is omitted during assembly of battery finished products, and the tab can not be broken by the aluminum tape due to the aluminum-to-nickel process, thereby saving production cost and increasing pass rate of products.
Description
Technical field
The utility model relates to a kind of lithium ion battery, relates in particular to the positive pole ear of lithium ion battery.
Background technology
Existing lithium ionic cell positive pole ear adopts the fine aluminium sheet to make, and aluminium pole ears adopts ultrasonic wave or Laser Welding welding nickel strap at the finished product assembling process, is easy to fracture.Light littleization along with electronic product, small electrical core demand is increasing, but the small electrical core is in the course of processing of back, use very little lug, the following cylindrical electric core of diameter 9mm particularly, use be that the aluminium pole ears width has only 1.5mm, and processing " aluminium-to-nickel " link is after electric core is made behind the electric core, by shaping, action such as bending aluminium strip etc. could and nickel strap overlap a plane and weld, be easy to cause aluminium strip to rupture.
The utility model content
At above defective, the technical problem that the utility model need solve is to omit the aluminium-to-nickel operation, solves the problem of lug fracture.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of positive pole ear of lithium ion battery, comprise lug glue bonding on aluminium strip and the aluminium strip, and also be welded with nickel strap on the described aluminium strip.
Further: in the positive pole ear of above-mentioned lithium ion battery, engage with aluminium strip firmly in order to make nickel strap, described solder joint is The more the better.Described nickel strap thickness can suitably be adjusted according to different battery specifications.The purity of nickel strap is the bigger the better.The distance of the welding center of described aluminium strip and nickel strap and the center of lug glue is≤20mm.
Compared with prior art, in the positive pole ear of above-mentioned lithium ion battery, comprise lug glue bonding on aluminium strip and the aluminium strip, promptly be shaped period at the aluminium strip lug, aluminium strip and nickel strap are carried out laser welding, do not need just can finish, be subjected to the influence of ultrasonic wave or Laser Welding vibrations less, stopped that aluminium strip ruptures through any shaping or bending.The electrode lug of this structure makes battery in the finished product assembling process, has omitted the aluminium-to-nickel operation, and the aluminium-to-nickel operation does not cause the problem of lug fracture so aluminium strip does not also exist.This technology has been saved production cost again, has improved the qualification rate of finished product.
Description of drawings
Fig. 1 is the structural representation of the utility model positive pole ear;
Wherein 1 aluminium strip, 2 lug glue, 3 nickel straps, 4 weld centers.
Specific embodiments
For the ease of those skilled in the art's understanding, describe in further detail below in conjunction with specific embodiment and 1 pair of the utility model structural principle of accompanying drawing:
As Fig. 1: a kind of positive pole ear of lithium ion battery, comprise lug glue 2 bonding on aluminium strip 1 and the aluminium strip, also be welded with nickel strap 3 on the described aluminium strip 1.Described solder joint is The more the better.The purity of nickel strap is the bigger the better.The welding center 4 of described aluminium strip and nickel strap with the distance of the center of lug glue is≤20mm.
In the positive pole ear of above-mentioned lithium ion battery, also be welded with nickel strap 3 on the described aluminium strip 1.The electrode lug of this structure makes battery in the finished product assembling process, has omitted the aluminium-to-nickel operation, and the aluminium-to-nickel operation does not cause the problem of lug fracture so aluminium strip does not also exist.
The above is a preferred embodiment of the present utility model, and under the situation that does not break away from the utility model design, any conspicuous distortion and the replacement carried out all belong within the utility model protection range.
Claims (2)
1. the positive pole ear of a lithium ion battery comprises lug glue (2) bonding on aluminium strip (1) and the aluminium strip, it is characterized in that: also be welded with nickel strap (3) on the described aluminium strip (1).
2. the positive pole ear of lithium ion battery according to claim 1, it is characterized in that: the distance of the welding center of described aluminium strip and nickel strap and the center of lug glue is≤20mm.
