Active material for a cathode of lithium ion battery and a method for preparing the same

摘要

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 DIFFERENCE 20 DEG C./min, combusting and calcinating the gel or liquid phase at 300 DIFFERENCE 400 DEG C. during 2 DIFFERENCE 3 hours is disclosed.
