METHOD FOR MAKING LITHIUM BATTERY CATHODE MATERIAL |
摘要 |
A method for making a lithium battery cathode material is disclosed. A mixed solution including a solvent, an iron salt material, a vanadium source material and a phosphate material is provided. An alkaline solution is added in the mixed solution to make the mixed solution have a pH value ranging from about 1.5 to 5. The iron salt, the vanadium source material and the phosphate material react with each other to form a plurality particles of iron phosphate precursor doped with vanadium which are added in a mixture of a lithium source solution and a reducing agent to form a slurry of lithium iron phosphate precursor doped with vanadium. The slurry of lithium iron phosphate precursor doped with vanadium is heat-treated.
