Introduction

Nickel Hydroxide, generally used in rechargeable battery electrodes, by oxidation to nickel(III) oxide-hydroxide. Nickel hydroxide is denoted by Ni(OH)2 and is an insoluble chemical compound having strong redox properties. The mineral form of nickel hydroxide, also known as theophrastite, was first discovered in northern Greece in 1980. Nickel Hydroxide is a translucent emerald-green crystal, formed naturally in thin sheet form near the boundaries of chlorite and idocrase crystals.

Nickel hydroxide has a molecular weight of 92.71 g/mol, having a melting point of 230?C. Nickel hydroxide has two distinct pseudopolymorphs, namely α- and β-Ni(OH)2 forms. The α structure is made up of Ni(OH)2 layers, having intercalated anions or water molecules between them.

The β type is a hexagonal closest-packed structure of OH- and Ni2+ ions, minus any kind of intercalated ions. Besides the α and β forms of nickel hydroxide, a number of γ-Ni(OH)2 have been described, which are made up of crystal structures having much bigger inter-sheet distances.

The global nickel hydroxide market is projected to register a high growth in demand due to the increasing requirements of nickel hydroxide as electrodes in electrochemical batteries.

The long battery life, utmost reliability, and superior performance of the nickel hydroxide based batteries, as compared to the other types of batteries are expected to fuel the growth of the global nickel hydroxide market. However, the toxicity concerns related to Ni2+ ions are poised to hinder the growth of the global nickel hydroxide market. Additionally, the rising prices of raw materials may hinder the growth of the global nickel hydroxide market over the forecast period.
