说明

一般說明

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.

應用

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.

特點和優勢

• 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.
