The pole is simply the core of the battery, the electrode, a positive and a negative, so as to use electricity, the ear is the part that is led out by the electrode, through the ear and other connections to power!
Manufacturing is totally different! Pole sheet must have a carrier and paste through the configuration of coating drying roller to form, 2 manufacturing is completely different, the material is different! The pole ear is a part of a soft-pack lithium-ion battery. The lithium battery pack is divided into positive and negative two poles, and the pole ear is an electrical conductor of metal material drawn from the positive and negative electrodes by the lithium cell. Generally, the positive and negative pole ears are the contact points when charging and discharging. The positive grade of the lithium battery pack uses aluminum raw materials, the negative grade uses nickel raw materials, and the negative grade also uses copper electroplated nickel raw materials, which are composed of two parts: plastic film and metal strip.
The pole ear in a battery is the part that exports the current from the pole plate to the battery terminal. Pole ear is a raw material for lithium-ion polymer battery products. For example, the mobile phone battery, Bluetooth battery, notebook battery and so on used in our life need to use the pole ear
