Abstract
The present invention relates to a method for preparing a lithium iron phosphate nanopowder coated with carbon, including the steps of (a) preparing a mixture solution by adding a lithium precursor, an iron precursor and a phosphorus precursor in a glycol-based solvent, (b) putting the mixture solution into a reactor, heating and concentrating to prepare a metal glycolate slurry, (c) drying the metal glycolate slurry to form a solid content, and (d) firing the solid content to prepare the lithium iron phosphate nanopowder coated with carbon, and a lithium iron phosphate nanopowder coated with carbon prepared by the method.
