Description
Technical Field
The utility model relates to a formula of book exempts from to change nickel utmost point ear technical field specifically is a formula of book exempts from to change nickel utmost point ear.
Background
The anode tab of the existing flexible package polymer lithium ion battery is made of pure aluminum, and the battery needs to be connected with other electronic elements during post processing, so that the anode and the cathode of the battery need to be welded (soldered), and the anode tab made of pure aluminum can not be tinned, namely can not be directly soldered, so that the anode tab of the flexible package polymer lithium ion battery needs to be subjected to material conversion and is converted into a material capable of being soldered.
The aluminum-to-nickel process for the anode tab of the flexible package polymer lithium ion battery has two basic methods, one is that the aluminum tab is welded by a laser welding machine in a tab production plant in the manufacturing process to produce a single tab with transferred nickel, the other is that the aluminum tab is directly produced into a single or disk-type aluminum tab without the aluminum-to-nickel process in the tab production plant, and after the battery production plant adopts the tab to produce a battery cell, the aluminum-to-nickel process is carried out by a metal ultrasonic welding machine or a laser welding machine in a post-processing section of the battery cell.
The former aluminum-nickel conversion process method is characterized in that in the process of manufacturing the battery core, the tab and the pole piece of the battery core can only be welded manually through a metal ultrasonic welding machine, a battery manufacturer needs to invest a large amount of manpower and equipment, and the quality of the battery is reduced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome current defect, provide a formula of book exempt from to change nickel utmost point ear, can realize automated production, solved originally because of the electric core of automatic film-making production, drop into a large amount of manual works and equipment again and carry out the aluminium and change nickel technology in the post-processing, improved battery production efficiency, reduced the disability rate of cost of labor and electric core, can effectively solve the problem in the background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a formula of book exempts from to change nickel utmost point ear, includes the aluminium strip, the aluminium strip coats and is stamped utmost point ear and glues, the both ends front side of aluminium strip is equipped with the connection piece, the both ends rear side of aluminium strip is equipped with the nickel strap.
Furthermore, laser welding spots are distributed on the front side of the connecting piece in an array mode, and therefore the tab is convenient to weld with the positive pole piece of the battery core.
Compared with the prior art, the beneficial effects of the utility model are that: the roll type rotation-free nickel electrode lug has the following advantages: laser welding is adopted to weld a section of nickel strap with the same thickness and width, the welding position is arranged at the two head parts of the nickel strap, the quantity of laser welding spots is formulated according to the width of a tab and the strength of process requirements, then the welded nickel strap and the aluminum strap at the superposed part of the aluminum tab are cut off by a precise die cutting machine, the first aluminum tab and the second aluminum tab are connected together by the welded nickel strap, and the steps are repeated, so that the aluminum-to-nickel tab capable of being rolled into a disc shape is manufactured, an automatic sheet making machine is used for cutting off twice, the tab with the required length is cut off for the first time to supply the battery pole piece for welding, the redundant section of the aluminum strap and the nickel strap for welding is cut off for the second time, and the automatic sheet making machine repeats the actions, so that the manufacturing of the disc type.
