Soft pack lithium-ion battery pole ear

Amazing! Understanding the pole ears of soft pack lithium-ion batteries

1. What is a battery earphone?

Sukhavati is an integral part of soft package lithium ion battery products. Batteries are divided into positive and negative electrodes. The electrode ear is a metal conductor that leads the positive and negative electrodes out of the battery. It is often said that the positive and negative electrodes of the battery are the contact points during charging and discharging. The positive electrode of the battery uses aluminum (Al) data, the negative electrode uses nickel (Ni) data, and the negative electrode also has copper nickel (Ni Cu) data. They are compounds composed of two parts: a thin film and a metal strip.

2. Classification of polar ears

2.1 According to the material of the pole ear metal strip:

Aluminum (Al) electrode lug: generally used as positive electrode lug. If the battery is Lithium titanate negative electrode, it can also be used as negative electrode lug.

Nickel (Ni) electrode ear: As a negative electrode ear, it is important for digital small batteries, such as mobile phone batteries, mobile power supply batteries, tablet computer batteries, intelligent transmission device batteries, etc.

Copper plated nickel (Ni Cu) electrode ear: used as a negative electrode ear and important for power lithium-ion batteries and high-power batteries.
