| Abstract: | In recent years, as a cathode active material of Zn-Ni battery and Ni-MH battery, nickel oxyhydroxide has gradually become a new research issue in the area of the battery materials. The mechanism of Zn-Ni battery and Ni-MH battery, and the preparations, the crystal structures and the electrochemical properties of nickel oxyhydroxides were reviewed, and the discharging specific capacity of nickel oxyhydroxide and reversible electrode potential of Ni(OH)2/NiOOH electrode were also analyzed. At last, according to the perspectives of high discharging specific capacity, low self-discharging rate and high density NiOOH, the research directions in the future were suggested. |
