Description

Nickel hydroxide (CAS 12054-48-7 ), also referred to commercially as Green nickel oxide, is an inorganic nickel compound used primarily as an active electrode material and as a precursor in nickel-based chemical synthesis. Its role spans energy storage, surface treatment, and catalyst manufacturing across several industrial sectors. In rechargeable battery production, it serves as the primary cathode active material in nickel-metal hydride and nickel-cadmium cells. This material directly determines charge capacity and cycle performance in energy storage systems. Electroplating and surface finishing operations use it as a nickel ion source for depositing corrosion-resistant coatings on automotive and industrial components. In catalyst manufacturing, it acts as a precursor for nickel-based hydrogenation and reforming catalysts used in petrochemical processing. Mining and metallurgical refining operations also use it as an intermediate in industrial processes. These operations involve converting nickel ore concentrates into refined nickel salts or metal. Nickel hydroxide is supplied as a fine green powder, with particle size and surface area specifications varying by application. Battery-grade material carries tighter controls than technical-grade for specific manufacturing needs. Battery-grade and technical-grade are the primary commercial distinctions for industrial procurement and supply chain management. Battery-grade product is held to stricter purity and morphology standards to ensure optimal performance. Bulk quantities are standard for industrial buyers, with packaging typically in drums or bulk bags for safe transport. Contact us for supply of Nickel hydroxide Request Quote
