Nickel Sulfate Hexahydrate (NiSO₄·6H₂O)

Description

1. Product Overview
Nickel Sulfate Hexahydrate (NiSO₄·6H₂O) is a high-purity, crystalline nickel salt essential as a precursor material for lithium-ion battery cathodes and industrial electroplating. Its primary industrial use is supplying nickel ions for the production of nickel-rich cathode materials (NMC, NCA) in electric vehicle batteries. The key value proposition lies in its consistent electrochemical purity, which directly enhances battery energy density and plating uniformity. With global EV adoption accelerating, securing a stable, high-grade nickel sulfate supply is a strategically critical lever in the battery supply chain.
