Document Type and Number:
WIPO Patent Application WO/2015/005551
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a nanopowder of a carbon-coated lithium metal phosphate and a nanopowder of lithium metal phosphate manufactured thereby, the preparation method comprising the steps of: (a) preparing a mixed solution by adding a lithium precursor, an iron precursor, and a phosphorous precursor to a glycol-based solvent; (b) preparing a metal glycolate slurry by injecting the mixed solution into a mixer, and heating and condensing same; (c) forming solids by drying the metal glycolate slurry; and (d) preparing the nanopowder of the carbon-coated lithium metal phosphate by firing the solids.
