    摘要： 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 triethanolamine solvent, (b) putting the mixture solution into a reactor and reacting to prepare amorphous lithium iron phosphate nanoseed particle, and (c) heat treating the lithium iron phosphate nanoseed particle thus to prepare the lithium iron phosphate nanopowder coated with carbon on a portion or a whole of a surface of a particle, and a lithium iron phosphate nanopowder coated with carbon prepared by the above method. The lithium iron phosphate nanopowder coated with carbon having controlled particle size and particle size distribution may be prepared in a short time by performing two simple steps. A lithium secondary battery including the lithium iron phosphate nanopowder coated with carbon thus prepared as a cathode active material has good capacity and stability.

    摘要： The present invention relates to a method for preparing a lithium iron phosphate nanopowder, including the steps of (a) preparing a mixture solution by adding a lithium precursor, an iron precursor and a phosphorus precursor in a glycerol solvent, and (b) putting the mixture solution into a reactor and heating to prepare the lithium iron phosphate nanopowder under pressure conditions of 10 bar to 100 bar, and a lithium iron phosphate nanopowder prepared by the method. When compared to a common hydrothermal synthesis method and a supercritical hydrothermal synthesis method, a reaction may be performed under a relatively lower pressure. When compared to a common glycothermal synthesis method, a lithium iron phosphate nanopowder having effectively controlled particle size and particle size distribution may be easily prepared.

Thus, a high temperature/high pressure reactor is not necessary and process safety and economic feasibility may be secured.
