Lithium-ion power battery pole ear, as the name implies, power battery pole ear is the pole ear used in power battery, its specification size, the current through value is very large.
Pole lug is a component of flexible package lithium-ion battery products. The battery is divided into positive and negative, pole ear is from the core will lead to the positive and negative metal conductive body, popular said that the battery positive and negative ears are in charge and discharge of the contact point. The positive electrode of the battery is made of aluminum, the negative electrode is made of nickel, and the negative electrode is also made of copper and nickel, which are made of two parts, film and metal strip.
Extremely ear including ear metal belt, ear one end of the metal belt and aluminum-plastic packaging film bags inside the plate connection, the other end extends to the bags are used, in the packaging mouth a pole ear metal belt by a film of polymer composite coating, metal belt in very ears and packing bags of polymer composite coating and adhesive is coated with a layer of liquid, The adhesive can be coated outside or inside or outside the bag mouth at the same time, the liquid adhesive after curing to form a curing film.
Characteristics of pole lug
1. In order to cause the cell to inflate, leakage mechanism as the research and development point, developed metal strip surface with special corrosion-resistant coating, at the same time using imported CPP glue and aluminum film inner CPP layer has good heat-sealing performance, excellent solution to the pole ear of the inflate, leakage and other problems.
2. Excellent electrolyte resistance and HF resistance.
3. Good bonding performance with the metal surface and aluminum-plastic film.
4. High melting point of the insulation layer effectively prevents short circuits formed between aluminum foil and aluminum plastic film.
5. The pole ear produced by imported material and special processing technology has strong corrosion resistance, leakage proof, and stable electric conductivity.
