50 Pieces Aluminum Lug Flexible Battery Lithium ion Battery Lug

The electrode lug is a raw material of lithium ion polymer battery products. For example, cell phone batteries, Bluetooth batteries, notebook batteries, etc. used in our life all need to use polar ears. The battery is divided into positive and negative electrodes. The electrode ear is the metal conductor that leads the positive and negative electrodes out of the electric cell. Generally speaking, the ears of the positive and negative electrodes of the battery are the contact points when charging and discharging. This contact point is not the copper sheet on the surface of the battery, but a connection inside the battery. The electrode lug is divided into three materials. The positive pole of the battery uses aluminum (Al) material, the negative pole uses nickel (Ni) material, and the negative pole also has copper nickel plated (Ni Cu) material. They are made of film and metal tape. The film is the insulating part on the pole lug, which is used to prevent short circuit between the metal strip and the aluminum plastic film during battery packaging, and to prevent liquid leakage by heating (about 180 ℃) and fusing with the aluminum plastic film during packaging. One lug consists of two pieces of film holding the metal tape between them. Size: width 4mm, thickness 0.1mm, length 61mm
