Pure nickel wire is a metal wire made of nearly 100% nickel, known for its excellent properties such as high corrosion resistance, high electrical and thermal conductivity, and strength at elevated temperatures. It’s commonly used in various industries, including electronics, automotive, aerospace, and chemical processing, for applications like:
Pure nickel wire has a wide range of applications in electrical components, mainly due to its excellent electrical conductivity, resistance to high temperatures, and its ability to withstand high temperatures.
1. Connecting wires and leads
Pure nickel wire is commonly used in the manufacture of connecting wires and leads for electrical equipment.
Its resistance to oxidation and corrosion makes it more durable and less susceptible to environmental influences when used in high-temperature or chemical environments.
2. Resistive and heating elements
Pure nickel wire can be used as resistance and heating element materials, because it can still maintain a stable resistance value at high temperatures, and will not be easily oxygenated.
For example, in some electric heating equipment, pure nickel wire is used to make electric heating wire or resistor, which can continue to operate at high temperatures without damage.
3. Battery Connection Terminals
Pure nickel wire is commonly used as a connection terminal material in battery manufacturing, especially in nickel-metal hydride and lithium-ion batteries. This is due to the low resistance and high electrical conductivity of pure nickel, which helps to improve the electrical performance of the battery.
Its corrosion resistance also ensures that during charging and discharging it can be used as a connection terminal.
4. Applications in high-frequency equipment
In some high-frequency and high-power equipment, pure nickel wire is used to make antennas or other high-frequency connecting elements. This is due to its ability to maintain good electrical conductivity in high frequency environments while

During the heating process, the resistance value of pure nickel wire changes relatively little with temperature, which makes it excellent in temperature control and heating efficiency.
3. Oxidation resistance
At high temperatures, many metals undergo oxidizing reactions, resulting in reduced performance or even failure. However, pure nickel wire has good oxidation resistance and is not susceptible to oxide formation or corrosion when used in air or other oxidizing atmospheres.
This means that pure nickel wire heating elements will not oxidize during long periods of operation at high temperatures, resulting in reduced heating efficiency or damage.

4. Application in battery assembly and spot welding
In the assembly of batteries, pure nickel wire is widely used in the spot welding process. Through spot welding, pure nickel wire can firmly connect the positive and negative electrodes and other conductive parts of the battery, ensuring that the internal current path of the battery is maintained.
Pure nickel wire for spot welding has good ductility and processability, which allows it to be adapted to the structure of the battery, thus meeting the needs of different battery designs.
5. Widespread use in NiMH and NiCd batteries
In nickel-metal hydride (NiMH) and nickel-cadmium (NiCd) batteries, pure nickel wire is the primary joining material. The chemistry of these batteries requires the use of materials that are corrosion-resistant and electrically conductive, and pure nickel wire meets this requirement.
Pure nickel wire is used to connect the electrodes and case of the battery together to ensure that the battery maintains good performance over long charge/discharge cycles. This is critical to increasing the cycle life of the battery and minimizing resistive losses.
6. Applications in lithium-ion battery manufacturing
In lithium-ion batteries (e.g., 3C batteries and power batteries), pure nickel wire is typically used to connect the battery lugs. Li-ion batteries need to strike a balance between high energy density and low internal resistance, and the high conductivity and low resistance properties of pure nickel wire can help optimize the internal connections of the battery.
The corrosion resistance and stability of pure nickel wire is especially important in the operating environment of lithium batteries, because lithium-ion batteries generate a variety of chemical reactions during charging and discharging, and the use of pure nickel wire ensures that these connections are not susceptible to damage at high temperatures and in chemical environments.
7. Improve the conductivity and stability of the battery
The application of pure nickel wire is not only limited to connection, but also can optimize the overall performance of the battery by enhancing the conductive network inside the battery. For example, by evenly distributing pure nickel wire inside the battery, the efficiency of current conduction can be enhanced and internal resistance can be reduced.
This approach is particularly effective in batteries for some high-power applications, such as power and energy storage batteries, and can help the battery charge and discharge faster.
8. Balance of durability and cost-effectiveness
Another major advantage of pure nickel wire in battery manufacturing is its long durability and cost-effectiveness. While copper or other metals can be substituted for pure nickel under certain conditions, the combined properties of pure nickel wire, including corrosion resistance, electrical conductivity, and ease of processing, make it a good balance of cost and benefit.
Pure nickel wire is widely used by battery manufacturers precisely because it can significantly improve battery performance while keeping production costs under control.
