METHOD OF PREPARING OLIVINE CATHOD MATERIAL FOR LITHIUM SECONDARY BATTERY
摘要
The present invention relates to a method of preparing olivine cathode materials for lithium secondary battery. More specifically, a method of preparing an olivine-based cathode material for secondary battery comprising the steps of: dissolving an iron supplying material, a lithium phosphate, and a phosphorous bearing material by adding an acid; forming a chelate polymer by adding a chelate agent and a polymerization agent in the solution of the dissolving step followed by heating; pyrolyzing the chelate polymer under reducing atmosphere; and thermally reducing the chelated polymer degraded during the pyrolysis is provided.
