Application:	Nickel(II) sulfate heptahydrate can be used in the research and development: • As a vital precursor to generate nickel-rich cathode materials (NMC, NCA) for lithium-ion batteries using co-precipitation process because of its simplicity, ease of scale-up, and ability to produce a homogeneous structure at the particle scale. • As a nickel source in the electrodeposition process to fabricate the Ni-NTNW (nickel nanotube network), which is then coated with the electroactive NiCo-LDH material to form the hierarchical supercapacitor electrode. • As a precursor to synthesize the nickel(II) cinnamate complex, which is a key component in the preparation of the metal chelate monomers. • To synthesize a highly efficient oxygen evolution reaction (OER) trimetallic Fe-Co-Ni electrocatalyst with other metal sulfates . • To synthesize high entropy alloy for coatings to improve hardness, wear resistance and corrosion resistance.
Features and Benefits:	• High purity with trace metal analysis (=< 15 ppm) for 32 elements, suitable for batteries. • High water solubility ideal for synthesizing composites for various applications. • Low ppm levels of metal ions including Al, K, Na, Mg, Cu, Co, etc.,7) 99.999% purity is ideal for nickel plating.
General description:	Nickel(II) sulfate heptahydrate, a water-soluble solid, is widely utilized in diverse industrial applications such as electrochemistry, catalysis, electronics, and optoelectronics. Its electrochemical properties make it a valuable component in the synthesis of electrode materials, which are employed in batteries, supercapacitors, and fuel cells.
