What are lithium battery 18650 3.7v tabs?

　　The tab is a component of a soft-pack lithium-ion battery. The lithium battery pack is divided into two poles, positive and negative. The tabs are metal conductors that lead out the positive and negative poles from the lithium battery. It is generally believed that the positive and negative tabs are the contact points during charging and discharging. The positive stage of the lithium battery pack is made of aluminum material, the negative stage is made of nickel material, and the negative stage is also made of copper electroplated nickel material. These materials are composed of two parts: plastic film and metal strip.

　　It is composed of a pole metal strip. One end of the pole metal strip is connected to the pole piece in a packaging bag made of aluminum-plastic packaging film. The other end is widened to the outside of the packaging bag mouth. A section of pole metal strip is at the exit of the packaging bag. The belt is covered with a film-like polymer material, and a layer of liquid adhesive is also covered at the junction between the tab metal belt and the polymer material, as well as the packaging bag. The adhesive can wrap It is coated inside or outside the mouth of the packaging bag with a layer of drying adhesive.

　　Features of Ji Er:

　　1. Based on the principle of causing gas expansion and liquid leakage in lithium batteries as the product development point, the surface of the copper sheet developed is coated with a unique corrosion-resistant coating. In addition, imported CPP glue and the CPP layer in the aluminum film are used to have excellent heat sealing properties. It effectively solves the problems of air swelling and night leakage on the copper sheet.

　　2. High-quality anti-lithium battery electrolyte and anti-HF properties.

　　3. It has good fusion properties with metal surfaces and aluminum-plastic films.

　　4. The cable sheath has a high melting point, which effectively prevents short circuit failure between the aluminum plastic film and the aluminum platinum.

　　5. The imported raw materials are processed through a unique process, making the tabs resistant to corrosion, leakage-proof and with stable conductivity.
