The tab is a raw material for lithium-ion polymer battery products. The tabs are the carrier for energy transfer between the battery and the outside world. Therefore, when the battery is discharged at a high rate, increasing the conductivity of the tabs can effectively improve the battery's rate discharge performance in the early stages of discharge. It is widely used in mobile phone batteries, Bluetooth batteries, laptop batteries, etc. used in daily life.
The battery is divided into positive and negative poles. The tabs are the metal conductors that lead the positive and negative poles out of the battery core. Generally speaking, the tabs on the positive and negative poles of the battery are the contact points during charging and discharging. This contact point is not the copper piece we see on the outside of the battery, but a connection inside the battery. The tabs are divided into three materials. The positive electrode of the battery is made of aluminum (Al) material, the negative electrode is made of nickel (Ni) material, and the negative electrode is also made of copper-plated nickel (Ni-Cu) material. They are both made of a film and a metal strip. become.
The tab material is made of pure aluminum foil with a purity greater than 99.9% and has high conductivity. The positive tab of the lithium-ion battery is made of 1050 aluminum foil or 1060 aluminum foil. Its conductivity is 369000 S/cm, which can greatly improve the rate discharge performance of the battery.
Pure aluminum foil used for pole lug materials has high plasticity, corrosion resistance, electrical conductivity and thermal conductivity. The process is simple and the price is cheap. It is a widely used aluminum foil material. Usually used in food packaging, capacitors, cable tapes, aluminum foil gaskets, etc.
MC Aluminum is a professional aluminum foil manufacturer. The surface of the aluminum foil base material produced for the tab materials is clean and free of oil stains, black silk, burrs, etc. The product models are complete and sold to many overseas countries and regions. We provide sample mailing service and guaranteed after-sales service, so users can order with confidence.
