Product Introduction:
Nickel(ii) Hydroxide, also known by its chemical formula Ni(OH)2, is a green solid with the formula Ni(OH). Although stable at room temperatures and pressure conditions, at higher temperatures it undergoes dehydration reactions which cause it to change into nickel oxide (NiO).
Nickel(ii) Hydroxide is nearly insoluble in water but can be dispersed with strong acids or bases. It has a relative density of about 4.3 and remains chemically stable in most environments, although in an oxidizing atmosphere it could oxidize and form nickel oxide.
From a chemical viewpoint, Nickel(ii) Hydroxide is an amphoteric compound with strong basic properties that reacts with acids to produce salts while reacting with strong bases to form nickel hydroxide. Furthermore, ammonia water reacts with it to form ammonia-nickel complex or reacting with sodium hydroxide under strong alkaline conditions to form soluble nickel salts. Electrochemistry wise, it exhibits excellent properties – particularly as an anode material in nickel-hydrogen batteries where it boasts excellent energy storage capacity and cycle life as an anode material.
Nickel(ii) Hydroxide’s physical properties are closely tied to its crystal structure. Usually, this material features hexagonal or layered structures with strong intercrystalline interactions and good air stability; its hexagonal configuration also helps maintain stable battery reactions as it actively participates in battery charge/discharge cycles. Under humid conditions it may experience slight hydration reactions that form water-containing nickel(ii) Hydroxide compounds; this typically does not alter its basic properties.
Nickel(ii) Hydroxide has many applications in energy technology, particularly battery technology. It is widely utilized as the negative electrode material in nickel-metal hydride batteries (Ni-MH) and nickel-cadmium batteries (Ni-Cd). Due to its excellent cycle stability and energy density during charge and discharge cycles, nickel(ii) hydrate batteries are widely used as electric vehicle, mobile phone, power tool and other battery applications for electric vehicles, It also serves water treatment applications and environmental protection initiatives by acting as an adsorbents for metal ions from water bodies.
Nickel(ii) Hydroxide is an impressive multipurpose chemical material with exceptional electrochemical activity and strong environmental adaptability, making it suitable for sustainable energy technologies such as batteries, catalysis and environmental protection.
