摘要
Aluminum\|cobalt co\|substituted \%α\%\|Ni(OH)\-2 was prepared by means of the titration method in a buffer solution,the structure was characterized by XRD analysis. With above mentioned \%α\%\|Ni(OH)\-2 as the positive electrode of a nickel\|metal hydride cell,the discharge performances were examined by constant\|current charge\|discharge experiments. In comparison with the electrodes made of aluminum substituted or cobalt substituted Ni(OH)\-2 materials,the aluminum\|cobalt co\|substituted composite electrodes possess an excellent electrochemical performance and are of practical significance.
