Abstract

Lithium-aluminum-cobalt-nickel oxide (LiAl_xCoyNi_1−x−yO₂) particles, generally used as cathode of lithium battery, were prepared by chemical coprecipitation from an aqueous solution of LiOH, Al(NO₃)₃, Co(NO₃)₂ and Ni(NO₃)₂ with NH₄OH. XRD, SEM and FTIR were used to examine the effect of nickel content on the product. FTIR patterns showed that increase in nickel content decreased the absorption strength of the peak of spinel structure of the product, attributed to the occupation by nickel in the aluminum sites. Particle size and electrical properties of the lithium-aluminum-cobalt-nickel oxide (abbreviated as LACNO) particles were also determined.
