Title:
METHOD FOR PREPARING CATHODE ACTIVE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/135490
Kind Code:
A1
Abstract:
A method for preparing a cathode active material is provided. The method for preparing a cathode active material can comprise the steps of: preparing a first metal oxide; preparing a second metal oxide having an oxygen ratio lower than that of the first metal oxide by heat treating the first metal oxide in a nitrogen-containing gas atmosphere; and preparing a lithium metal oxide by firing the second metal oxide and a lithium salt.
