Description
Technical field
The utility model relates to lithium ion cell polar ear manufacturing technology, and especially a kind of lithium ion battery exempts from the production technology turning nickel positive pole disc type lug.
Background technology
Lithium battery when producing needs battery core to weld with route protection plate, carries out charge/discharge operation under making battery core can have the condition of safety guarantee at one.The positive pole of current lithium ion battery generally all adopts aluminium to make, and because aluminium tin-welding is poor, can not directly weld with route protection plate, usually needs to weld one section of nickel material by positive pole aluminium, is welded together by baffle (i.e. aluminium-to-nickel processing) by nickel material.Present lug mainly contains manual board-like and disc type two kinds, disc type lug is the needs in order to adapt to the automated production of battery core factory, the positive pole ear that these two kinds of modes are produced all needs after Battery Plant's battery core is made, and to be burn-on one end of positive pole ear aluminium strip nickel strap by the mode that manually turns nickel, this kind turns nickel mode and bother very much, process is complicated, production efficiency is low, and quality is unstable, there is rosin joint and crosses the situation of welding, welding position aluminium frangibility, causes fraction defective higher when battery Pack.Also there is disc type positive pole ear directly to take a turn for the better nickel, solve the problem of automation, but this disc type lug also exists some problems; as weld easily fractures; in order to protect welding position also to need a coated circle adhesive tape in welding position, this also increases operation, adding production cost.
Utility model content
The utility model is mainly in order to solve the variety of problems existing for prior art, and the continuous disc type positive pole ear of a kind of lithium ion battery with exempting to turn nickel is provided, meet the demand of the battery core production automation operation of battery core factory and welding operation, this lug eliminates the process of aluminium-to-nickel, improves production efficiency.
The utility model is for solving the problems of the technologies described above by the following technical solutions:
Lithium ion battery is with exempting from the continuous disc type positive pole ear turning nickel, and comprise reel and the winding of continuous reeling on reel, described winding comprises winding base material, and winding base material distributes some lugs; Described lug comprises the metal level of lug flexible glue block and Yi Shangxi, arranges the metal level of tin easily between adjacent lug flexible glue block.
The metal level of described easily upper tin is that nickel metal layer, silver metal layer, tin metal layer or copper add nickel metal layer.
The metal layer thickness of described easily upper tin is 2 to 5um, long 5 to 15mm.
Described winding base material is aluminium winding base material.
The metal level of described easily upper tin is plated on the outer surface of winding base material.
Described lug flexible glue block is divided into upper and lower two pieces, and is symmetrical arranged and is coated on winding base material.
The utility model adopts above technical scheme compared with prior art, has following technique effect:
A kind of lithium ion battery that the utility model provides is with exempting from the continuous disc type positive pole ear turning nickel, aluminium winding base material is provided with the metal level of tin easily, meet the demand of the battery core production automation operation of battery core factory and welding operation, this lug eliminates the process of aluminium-to-nickel, do not need extra to turn nickel nickel material and the coated adhesive tape turning nickel position, improve production efficiency, reduce the production cost of lug manufacturer and battery core factory, reduce the fraction defective in battery core Pack process.
Especially have employed and add the metal level of nickel metal layer as easy upper tin using nickel metal layer, silver metal layer, tin metal layer or copper, and thickness is between 2 to 5um, length is between 5 to 15mm, and conductivity is good very well, and mechanical performance is outstanding.
