Abstract:	Nanostructured, aluminum-stabilized nickel, hydroxides described as Ni1-xAlx(OH)2.(CO3)x/2·nH2O (x = 0.05-0.2), which are similar to α-Ni(OH)2·xH2O in crystal structure are examined as cathode materials for Ni-Cd cells. The structure, morphology and electrochemical performance are investigated. The structural changes and stability of nanophase aluminum-stabilized, alpha nickel hydroxides with different x values analyzed during cycling by means of powder X-ray diffraction. Compared with β-Ni(OH)2, the nanophase, aluminum-stabilized α-Ni(OH)2 with x = 0.15 is highly stable against overcharge.
