Application

Electroplating field

Nickel sulfate is the main source of nickel salt for electroplating nickel and chemical nickel plating. During the electroplating process, it can provide uniform nickel ions on the surface of the plated object. Under the action of the electric field, these nickel ions will obtain electrons on the surface of the cathode (the plated object) and be reduced to metallic nickel, thereby forming a uniform and dense nickel coating. For example, in the electroplating of automotive parts, the use of nickel sulfate can make the surface of the parts obtain a nickel coating with good wear resistance and corrosion resistance, extending the service life of the parts.

Nickel sulfate can be used in combination with other additives (such as brighteners, leveling agents, etc.) to adjust the performance of the coating. Brighteners can make the surface of the coating brighter, and leveling agents can reduce the roughness of the surface of the coating. By reasonably controlling the concentration of nickel sulfate and additives, coatings with different appearance and performance requirements can be obtained.

Chemical industry

As a catalyst, nickel sulfate plays an important role in organic synthesis reactions. For example, in some hydrogenation reactions, it can form a catalyst system with other metal compounds to accelerate the reaction. Nickel ions can adsorb reactant molecules and change the activation energy of the reactant molecules, making the reaction easier to occur.

Used to produce other nickel compounds. By reacting with other chemical reagents, a series of nickel compounds can be synthesized, which are widely used in pigments, battery materials and other fields.

Battery industry

It is used in the production of various batteries such as nickel-cadmium batteries, nickel-hydrogen batteries and lithium-ion batteries. Taking nickel-hydrogen batteries as an example, nickel sulfate is an important raw material for preparing positive electrode material nickel hydroxide. During the battery charging and discharging process, nickel hydroxide undergoes redox reactions to achieve mutual conversion of electrical energy and chemical energy. The nickel element provided by nickel sulfate can ensure the stable performance of the positive electrode material, thereby extending the cycle life of the battery and increasing the battery capacity.

Printing and dyeing industry

Nickel sulfate can be used as a mordant. Mordants can enhance the binding force between dyes and fabric fibers. It can first combine with fabric fibers and then react with dyes to form a complex chemical bond or adsorption effect, so that the dye is more firmly attached to the fabric and improve the fastness and uniformity of dyeing.
