What is Nickel(II) Hydroxide?
Nickel hydroxide chemical formula Ni(OH)2, NiO · xH2O. Eco-friendly hexagonal crystal. Somewhat soluble in water, conveniently soluble in acid and ammonia, insoluble in liquid ammonia. When home heating, slowly dry out to 230 ℃, a lot of them become nickel oxide (II), and also full dehydration calls for red heat. It can not be oxidized in air or hydrogen peroxide, yet it is simple to form nickel hydroxide (III) in ozone. Under alkaline conditions, it can be oxidized by chlorine and bromine, but not by iodine.
Nickel hydroxide can be prepared by various methods, mainly involving the reaction of caustic soda or caustic potassium with soluble nickel salt. Therefore, treating nickel sulfate solution with sodium hydroxide will form a large amount of green gel. Gel crystallizes during long-term storage. Alternatively, the neutralization solution forms a fine deposit of nickel hydroxide. Nickel nitrate is also used as a raw material for the preparation of nickel hydroxide. After its aqueous solution is treated with sodium hydroxide or potassium hydroxide, gel like nickel hydroxide precipitation will be produced, and high-purity products can be obtained by hot wine extraction.
Using nickel metal as anode and nickel nitrate solution as electrolyte, high-purity nickel hydroxide was prepared by electrolysis. Nickel hydroxide is electrodeposited on an inert cathode.
Nickel(II) Hydroxide Uses
- Nickel hydroxide can be obtained by including potassium hydroxide into nickel nitrate or nickel hexaammonium nitrate (II) nitrate service, which can be utilized as oxidation stimulant.
- Because of its redox behavior, it can be used as a rechargeable battery electrode. It can be used to store electrochemical energy and has potential applications in automotive batteries. It is a potential material for many biological applications, such as quantitative analysis of chromosome DNA.
- In the study of the effect of piling mistakes on the electrochemical activity of Ni (OH) 2 electrode, nickel hydroxide was utilized as a recommendation material.
- Nickel hydroxide can be obtained by treating the nickel sulfate solution with sodium hydroxide or by extracting the precipitate formed by the reaction of nickel nitrate and potassium hydroxide with hot ethanol. Nickel hydroxide is used in the manufacture of nickel-cadmium batteries and as an intermediate product in the manufacture of nickel catalysts.

Application of Nickel(II) Hydroxide
CN201711309111.0 discloses a preparation method of nickel hydroxide composite positive electrode material for alkaline secondary battery, comprising steps:
- Sodium hydroxide aqueous solution, EDTA aqueous solution and mixed brine solution are respectively dripped continuously in the reactor of the suspension of nickel hydroxide and stirred, the product of gained is separated, and gained solid matter is washed with deionized water, drying to obtain cobalt, magnesium doped nickel hydroxide active material.
- Mix carbon airgel, cobalt hydroxide, cobalt-magnesium doped nickel hydroxide, and nano-zinc powder evenly, add the above-mentioned lignin and polytetrafluoroethylene binder and stir evenly with an appropriate amount of water to obtain nickel hydroxide Composite cathode material.
The nickel hydroxide composite positive electrode material for alkaline secondary batteries prepared by the present invention has improved its conductivity and cycle stability while maintaining high energy density, so when the material is used in alkaline secondary batteries, it can The battery has a high specific capacity and a long service life.
