AL-tab lead、Ni/cu-tab lead

A product composed of a polymer film (sealant) and a metal conductor material through heat sealing composite materials. Suitable for flexible packaging of lithium-ion batteries, it has properties and functions such as conductivity, thermal conductivity, sealing, and insulation. The products are mainly divided into two categories: 1. Digital tab lead: Used for 3C consumer goods, such as mobile phones, drones, robot vacuum cleaners, mobile power supplies, e-cigarettes, Bluetooth earphones, driving recorders and other electronic products; 2. Power tab lead: used for new energy electric vehicles, energy storage stations, emergency power sources, backup power sources for base stations, etc. The tab lead is divided into three materials. The positive electrode of the battery uses aluminum (Al) material, the negative electrode uses nickel (Ni) material, and the negative electrode also has copper nickel (Ni Cu) material, both of which are composed of a thin film and a metal strip. The main function is to prevent short circuits between metal strips and aluminum-plastic film during battery packaging, as well as to prevent liquid leakage through heating and aluminum-plastic film sealing during the packaging process. This product has three main characteristics: 1. Adopting a smooth process, PP insulating colloid uniformly adheres to the metal surface, and the tensile curve is stable; 2. The total thickness range is small, and the total thickness of the ear (PP insulation adhesive thickness plus metal thickness) is uniformly controlled and maintained at ≤ 10um; Under the conditions of low tensile strength attenuation and adhesion testing (85 ° * 24h+1000ppm), when tested at a rate of 20mm/min and an angle of 180 °, the peel strength of the adhesive with a thickness of 100um is greater than 1.8N/mm, and the peel strength of the adhesive with a thickness of 150um is greater than 2.2N/mm.
