发明名称 METHOD FOR PREPARING LITHIUM IRON PHOSPHATE AS A POSITIVE ELECTRODE ACTIVE MATERIAL FOR A LITHIUM ION SECONDARY BATTERY
摘要 Disclosed herein is a method for preparing lithium iron phosphate as a positive electrode active material for a lithium ion secondary battery comprising drying and sintering a mixture containing a lithium source, ferric oxide, phosphoric acid, a carbon source, and a solvent, in which the solvent is water and/or water soluble organic solvent. The lithium iron phosphate prepared by the inventive method has small particle size and uniform particle size distribution, and the battery prepared from the lithium iron phosphate has high initial discharge specific capacity, and good large-current discharge property and cycle performance.
