Nickel cathodes are used in alloy manufacturing and electroplating.
Nickel cathodes are high-purity forms of nickel—typically 99.9% to 99.99% pure—produced through electrolytic refining. They serve as the foundational raw material for stainless steel production, high-performance alloys, and the rapidly growing electric vehicle (EV) battery market.
Primary Applications
Battery Technology: Nickel is a core component in ternary cathode active materials like NMC (Nickel, Cobalt, Manganese) and NCA (Nickel, Cobalt, Aluminium). Higher nickel content directly increases the energy density and driving range of EVs.
Stainless Steel & Alloys: Nickel cathodes are critical for manufacturing austenitic stainless steels (e.g., grades 304 and 316). They also create superalloys like Inconel and Monel, which withstand extreme heat and corrosion in aerospace and chemical plants.
Electroplating: Used as soluble anodes in plating baths (like Watts or Wood baths) to deposit protective or decorative nickel coatings on automotive parts and electronics.
Industrial Catalysts: High-purity nickel acts as a catalyst in petrochemical refining for sulfur removal and the production of low-sulfur fuels.
Physical Specifications
Forms: Commonly supplied as full plates (approx. 1m x 1m), cut squares (e.g., 1×1, 2×2, or 4×4 inches), pellets, or briquettes to suit different industrial feeding systems.
Properties: They exhibit excellent electrical and thermal conductivity, high corrosion resistance, and magnetic properties suitable for specialized electronic components.
Key Industry Suppliers
Global Leaders: Major producers and technology providers include LG Chem, POSCO Chemical, Sumitomo Metal Mining, and Nornickel.
Market Dynamics: Pricing is heavily tied to the London Metal Exchange (LME) nickel rates, which are volatile due to the surge in EV demand.
Safety & Handling
Risks: Nickel is classified as a skin sensitizer and can be harmful if swallowed. Proper personal protective equipment (PPE) is required during handling.
Storage: Should be kept in a dry, climate-controlled environment to prevent surface oxidation, which can compromise plating quality.
