Description

Folding-resistant sheet type aluminum tab

Technical Field

The utility model belongs to the technical field of battery and relevant accessory, especially, relate to a resistant folded sheet formula aluminium utmost point ear.

Background

The tab is a raw material of a lithium ion polymer battery product. The battery is divided into a positive electrode and a negative electrode, the tabs are metal conductors leading out the positive electrode and the negative electrode from the battery core, and the ears of the positive electrode and the negative electrode of the battery are contact points during charging and discharging; this contact point is not the copper sheet that we see on the outside of the cell, but rather a connection inside the cell. The tab is divided into three materials, the anode of the battery uses aluminum (Al) material, the cathode uses nickel (Ni) material, the cathode also has copper nickel plating (Ni-Cu) material, they are formed by compounding film and metal band, the film is the insulated part on the tab, it can prevent the short circuit between the metal band and the aluminum plastic film when the battery is packaged, and it can prevent the leakage by heating (about 140 deg.C) and the aluminum plastic film hot melting sealing bonding together when the battery is packaged. One tab is sandwiched by two sheets of film. The finished product package of the tab is divided into a disc type (the whole metal belt is wound into a disc after a film is added through equipment) and a plate type (the metal belt is cut into single pieces after the film is added, then the single pieces are placed in rows and clamped between two thin transparent plastic sheets), the positive tab made of pure aluminum can not be directly subjected to tin soldering, the existing process is generally to weld a nickel belt at the leading-out end of the positive tab of the battery and then perform tin soldering through the nickel belt, and the process is called as the positive tab aluminum nickel conversion process of the flexible package polymer lithium ion battery; however, after the existing sheet type aluminum tab is produced and processed, the aluminum tab is usually stacked together and stored in a box or case, and then used for subsequent battery assembly and use, which is very inconvenient for workers to take and is easy to prick, and the aluminum tab or the aluminum-to-nickel tab cannot be regularly placed, so that the subsequent production operation is inconvenient, meanwhile, because the aluminum tabs are stacked mutually, the welding part of the aluminum tab and the nickel sheet is easy to break in the subsequent moving process, the process stability is not high, the aluminum tab or the aluminum-to-nickel tab is easy to damage, so that the material is wasted, and no matter the aluminum tab or the aluminum-to-nickel tab is made of soft material, the thickness is thin, so that the aluminum tab or the aluminum-to-nickel tab is easy to bend, so the aluminum tab needs to be subjected to folding resistance treatment, the existing aluminum tab has large application limitation, and cannot meet the requirements in practical use, so that an improved technology is urge, to solve the above problems.
