Abstract (en)
[origin: WO0014818A1] An alpha phase nickel hydroxide active material for use in the positive electrodes of rechargeable alkaline electrochemical cells in which the material comprises nickel and hydroxide constituents and first and second stabilizing cations. The first stabilizing cation is selected from the group comprising: Al, Co, La, Ce, Y, Nd, Mg, In and Mn. The second stabilizing cation is selected from the group comprising: Mg, Zn, Co, Sr, Y, Nd, La, Ce and In. The alpha phase material exhibits an increased discharge plateau voltage profile, is structurally stable and possesses multi-electron per nickel atom transfer capabilities. The higher discharge plateau voltage and improved storage capacity translates into a significant increase in specific energy density and power density in operating cells.
