In this paper, the recent development of preparation methods of nickel oxy-hydroxide(NiOOH) and its application are summarized. Firstly, the relations between the crystal structures and the instability of NiOOH and its preparation methods are described. Then chemical oxidation method and electrolytic oxidation method are introduced and compared. As a new idea, the electrolytic-chemical oxidation method is put forward. Finally, the development trends of methods of preparing NiOOH are discussed.
