The tab is a component of a pouch cell lithium-ion battery product.

The battery is divided into a lithium battery anode materials and lithium battery cathode materials. The electrode ear is a metal conductor that leads the positive and negative electrodes from the battery core. In layman's terms, the ears of the positive and negative electrodes of the battery are the contact points during charging and discharging.

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 nickel-plated (Ni-Cu) material, which are all composited by film and metal strip.

2. Nickel (Ni) tabs: used as negative tabs, mainly used in small digital batteries, such as mobile phone batteries, mobile power batteries, tablet computer batteries, smart delivery device batteries, etc.

3. Nickel-plated copper (Ni—Cu) tabs: used as negative tabs, mainly used in power batteries and high-rate batteries.

3. White plastic tabs: generally used in high-end digital batteries, power batteries and high-rate batteries.
