Structural stability of aluminum stabilized alpha nickel hydroxide as a positive electrode material for alkaline secondary batteries

摘要

Nanostructured, aluminum-stabilized nickel, hydroxides described as Ni_1-yAl_x(OH)_2.(CO_3)_x/2.nH_2O(x=0.05-0.2), which are similar to α-Ni(OH)_2.xH_2O in crystal structure are examined as cathode materials for Ni-Cd cells. The structure, morphology and electrochemical performance are investigated.
