Product Specification

0.15mm-0.2mm Thickness Pure Nickel Alloy Strip For 18650 Cylinder Battery Welding

Product Introduction

Pure nickel strip is a key material in battery manufacturing, known for its high purity (usually above 99.95%) and excellent conductivity, which can effectively reduce the internal resistance of the battery and improve power output. Its good corrosion resistance keeps it stable in the battery electrolyte, extending the battery life. Pure nickel strips also have good mechanical properties and are suitable for manufacturing components such as battery terminals, connectors, and spacers, ensuring efficient current transmission and stability of battery systems. Through high-precision rolling processes and strict quality control, pure nickel strips meet the high standard requirements of battery manufacturing, significantly improving the performance and reliability of batteries, and providing strong support for technological progress and product innovation in the battery industry.

Specific Applications

Pure nickel strips have various important applications in battery manufacturing, mainly due to their excellent conductivity, corrosion resistance, and mechanical properties:

• Negative electrode current collector: In lithium batteries, pure nickel strips are commonly used to manufacture negative electrode current collectors, replacing traditional copper strips. Due to the low resistivity of nickel, it can improve the energy density and power of batteries.
• Battery ear: The ear is an important part of the battery responsible for transmitting current. The use of pure nickel strips as electrode ear materials can enhance the stability and efficiency of current transmission.
• Connecting piece and lead out piece: In a battery pack, connecting piece and lead out piece are used to connect various battery cells to transmit current. Pure nickel strips are widely used as materials for these components due to their excellent conductivity and corrosion resistance.
• Improving battery performance: The low internal resistance and antioxidant properties of pure nickel strips help to extend the discharge time of the battery, making the spot welding of the battery more secure, thereby improving the overall performance of the battery.

These applications make pure nickel strips an indispensable material in battery manufacturing, especially in the field of new energy batteries.

Advantages and Characteristics

1. Excellent conductivity: Pure nickel strip has high conductivity and low resistance, which can effectively reduce the internal resistance of the battery, improve the power output and charge discharge efficiency of the battery.
2. Good corrosion resistance: It performs well in various acidic and alkaline environments, especially in alkaline media, and has excellent corrosion resistance, which can effectively extend the service life of batteries.
3. High mechanical strength and ductility: Pure nickel strips have good mechanical properties and are easy to process into various shapes, making them suitable for manufacturing components such as battery lugs and connectors.
4. Chemical stability: In harsh environments such as high temperature and high humidity, pure nickel strips can maintain stable chemical properties, improving the safety and reliability of batteries.
