Product Overview
Nickel Sulphate (NiSO₄·6H₂O, 22% Ni) is the dominant nickel compound in lithium-ion battery cathode production, consumed in greater quantity than any other precursor salt in NMC and NCA chemistries. As automotive OEMs push toward higher-nickel cathodes (NMC 811, NMCA) for maximum energy density, nickel sulphate demand is experiencing exponential growth. Dongkwang Poland sources battery-grade NiSO₄ from Class 1 nickel refiners in Europe, Australia, and Asia, ensuring the high purity (≥99.5% Ni basis) required for next-generation battery cells.
How Nickel Sulphate (NiSO₄) Works
In cathode precursor manufacturing, NiSO₄ is the primary metal source in the co-precipitation reactor, combined with MnSO₄ and CoSO₄ to form Ni(OH)₂-based precursor particles with precisely controlled morphology, particle size distribution, and tap density. The nickel content directly determines the cathode’s specific capacity — higher Ni ratios (NMC 811: 80% Ni) deliver higher energy density but require tighter process control and purity specifications.
Key Benefits
Application Guide
Battery precursor production: co-precipitated at controlled pH (10.5-11.5) and temperature (50-60°C) in CSTR systems. Electroplating: dissolved in Watts-type nickel baths for decorative and functional coatings. Catalyst preparation: impregnated on supports for hydrogenation catalysts. Textile mordanting: historical use for dyeing. Process parameters are customer-specific — our technical team provides application support.
Ideal For
Storage & Handling
Store in dry conditions in sealed containers. NiSO₄ is classified as Category 1A carcinogen (inhalation), skin sensitiser, and aquatic toxicant. Full PPE mandatory: P3 respirator, nitrile gloves, safety goggles, protective suit. Strict occupational exposure limits apply (OEL: 0.01 mg/m³ as Ni). ADR Class 6.1 for transport. Environmental release must be prevented.
