詳細

詳細

Nickel(II) sulfate hexahydrate possesses a tetragonal crystal structure and is classified as a rare mineral called retgersite. This compound has a distinct blue-green color and demonstrates high solubility. It is insoluble in ethanol and ammonia. It is commonly used as a reliable source of Ni²⁺ ions for electroplating processes. Nickel(II) sulfate hexahydrate is a paramagnetic in nature.

アプリケーション

Nickel-rich cathodes are widely favored due to their exceptional energy density and impressive rate capability for Lithioum-ion batteries. Nickel stands out for its ability to provide higher cell voltage, maintain a consistent voltage profile, and exhibit delocalized electron density, resulting in excellent electronic conductivity.

Therefore, Nickel(II) sulfate hexahydrate has been widely used as a key component for the synthesis of Cathode for Lithium-ion batteries. - Spherical NCM 622 and Li[Ni0.9Co0.05Mn0.05]O2 (NCM 900505) were synthesized via a co-precipitation method using Nickel(II) sulfate hexahydrate. In order to achieve the desired energy density, it is necessary to maximize both the nickel content in the cathode and the cutoff voltage. [] - to synthesis single-crystal, Ni-rich NCM and polycrystalline NCM cathodes with various Ni content by coprecipitation method . These Ni-rich layered cathodes like NCM, NCA, and NCMA ([Ni1–x–yCox(Mn and/or Al)y]O2) are the top choices for powering upcoming electric vehicles. It is found that polycrystalline NCM cathodes are prone to intergranular microcracking during cycling, single crystal NCM cathodes demonstrate resilience against mechanical fracture, even under highly charged conditions or repeated cycles. Due to limited lithium-ion diffusion pathways, the electrochemical performance of single crystal -NCM cathodes, particularly in terms of capacity and cycling stability, is lower compared to that of polycrystalline-NCM cathodes. The difference in the electrochemical performance of single crystal -NCM and polycrystalline-NCM cathodes grows as the Ni fraction increases. In addition, Nickel(II) sulfate hexahydrate is widely used for electroplating for producing metallic coatings. Nickel(II) sulfate hexahydrate can also be used as a catalyst in: -Pt50Ni50 catalysts supported on MCM-41 were produced using wet co-impregnation. These catalysts were then employed for hydrogenation reactions of benzene in gas phase. The morphology of the metal phase within the catalysts has a notable impact on the conversion of benzene to cyclohexane. Factors like reduction temperature, NaBH4 concentration, and reduction medium influence the particle morphology. []
