99.95 Nickel Foil

The irreplaceability of 99.95% high-purity nickel foil stems from its absolute match between purity and cutting-edge application requirements. In the field of new energy, it is the preferred material for the positive electrode current collector of ternary lithium batteries. Its extremely high purity ensures that there are almost no side reactions when in long-term contact with highly active positive electrode materials (such as NCM/NCA) and corrosive electrolytes, fundamentally ensuring the energy density, cycle life, and safety boundary of the battery. Any trace impurities may become a hidden danger of performance degradation. In addition, in the fields of high-end electronics, vacuum coating, and specialty chemicals, a purity of 99.95% is the physical basis for its excellent conductivity, stable corrosion resistance, and ultimate process consistency. These properties cannot be compensated for by later processes, making it the only solution for performance and reliability in these high-end applications, irreplaceable.

Due to its extremely high purity, 99.95 nickel foil exhibits the following outstanding properties:

• Excellent corrosion resistance: It has strong resistance to alkaline solutions, non oxidizing acids, and various corrosive media, and has good oxidation resistance.
• Good conductivity and thermal conductivity: High purity results in higher electronic and thermal conductivity efficiency, with extremely low losses caused by impurities.
• Outstanding ductility and processability: The texture is soft and easy to perform deep processing such as stamping, stretching, bending, and wrapping without breaking.
• More stable mechanical properties: The extremely low impurity content reduces internal defects in the material, making its performance more uniform and predictable.

Common specification parameters:

• Brand: N4 (Chinese National Standard GB/T 2056-2005)
• Purity: Ni+Co ≥ 99.95%
• Thickness: Typically ranging from 0.01mm (10 μ m) to 0.1mm, customizable.
• Status: Soft (M), Hard (Y), etc., meeting different hardness requirements.
• Form: Roll material (can be cut), sheet material.

When you need to purchase 99.95 nickel foil, you should not only focus on the price, but also pay attention to:

• Purity assurance: Is there an authoritative material certification (MTC/COA) to ensure that the ingredients accurately meet the N4 standard.
• Quality stability: Whether the thickness tolerance, surface smoothness (without scratches, oil stains, oxidation), and edge burrs of the foil material are strictly controlled.
• Application performance: Especially when used for batteries, whether its tensile strength, elongation, surface tension and other indicators meet the requirements of coating and rolling processes.
• Supplier qualification: Whether it has mature production processes and a stable quality control system.

The 99.95% (N4) high-purity nickel foil produced by Shaanxi Zhongheng Weichuang Metal Materials Co., Ltd. strictly follows the above standards and is widely used in high-end lithium battery current collectors and other industrial fields due to its excellent consistency, low defect rate, and outstanding deep drawing processing performance. It is your trusted choice.
