5p Pure Nickel Strip 21700

5P pure nickel strip 21700 is is a high-performance pure nickel material mainly used for welding lithium batteries,connection, pole ear welding, battery module assembly, etc. of 21700 lithium battery packs. It is made of high-purity nickel or nickel plated steel strip, with stable electrical resistivity, which can ensure the stability and consistency of the battery during use, especially suitable for high-temperature applications. The pure nickel material makes it easy to weld, which can achieve stable connection between battery components and ensure the reliability of the battery pack. Its standardized design can also save customers the workload of assembling the battery pack. We offer a range of thicknesses between 0.1mm and 300mm, which can also be customized for use in power battery packs, energy storage systems, and electric vehicle battery modules.

✥Electrode connection plate: used for welding the positive and negative electrode ears of cylindrical lithium batteries such as 18650, 21700, 26650, 32650, etc.

✥Power battery pack: suitable for series parallel welding of high-power battery packs such as new energy vehicles, electric tools, energy storage systems, etc.

✥3C electronic product batteries: Ear connections for consumer lithium batteries such as smartphones, laptops, drones, etc.

✥Precision electronic components: conductive connectors for devices such as capacitors, resistors, relays, etc.

✥FPC (Flexible Circuit Board): a substitute for some copper materials, used in special circuit scenarios that require high corrosion resistance.

The following is a detailed production process for 5P pure nickel strip 21700：

1.Raw material selection: Choose ultra-high purity electrolytic nickel plate.

2.Pre treatment: Clean the surface of nickel blocks to remove oxide layers and impurities.

3.Smelting: Put the prepared raw materials into the furnace for smelting, so that various components can be fully fused.

4.Ingot: pulled into semi-finished products under vacuum conditions, hot forged into shape.

5.Precision rolling: Heating nickel ingots that have undergone milling/planing treatment to an appropriate temperature.

6.Bright annealing: hydrogen or vacuum annealing to eliminate work hardening and improve ductility.

7.Surface treatment: Clean or brush the surface of annealed nickel strip.

8.Slitting/edge cutting: The nickel strip is processed by slitting or edge cutting, and cut into the desired width and length.

Our workshop has high-precision pneumatic presses, CNC punching machines, laser welding machines, polishing machines, CNC milling machines, polymer bending welding machines, bending machines, and other OEM product processing machines provided to customers.
