Abstract

This paper reports the synthesis of monodisperse spherical LiCoO₂ particles in a wide range of average diameter using a urea-based-uniform-precipitation method. The average diameter of LiCoO₂ particles can be varied from 2 to 14 lm with a uniform size distribution. The effective approach to maintain the size uniformity while changing the average size of LiCoO₂ particles is to keep the ratio of [CO(NH₂)₂] to [CoSO₄] at 8 even when the CoSO₄ and urea concentrations are changed.
