Nickel sulfate is crucial in industry, mainly for electroplating to provide corrosion-resistant coatings on metals for automotive, plumbing, and electronics, and as a key ingredient in making rechargeable batteries (NiCd, NiMH, Li-ion cathodes). It's also vital for producing nickel catalysts, pigments for ceramics, and acts as a mordant in dyeing textiles, leveraging its high purity and solubility for diverse chemical and surface treatments
