Abstract
A process for preparing an active material for a cathode of a lithium ion battery comprising the steps of: dissolving lithium hydroxide, manganese acetate as starting materials into water to form a solution; adding a chelating agent into the solution; producing gel or liquid phase by evaporating the solution; and producing a powder by raising temperature at the rate of 5.about.20 .degree. C./min, combusting and calcinating the gel or liquid phase at 300.about.400 .degree. C. during 2.about.3 hours is disclosed.
