The lithium iron phosphate nano powder prepared the present invention relates to the preparation method of lithium iron phosphate nano powder and according to the above method, the above method include：Step (a), lithium precursor, iron precursor and phosphorus precursor are put into Glycerol solvents to prepare mixed solution；And step (b), put into above-mentioned mixed solution to reactor and heated, 1 bar less than 10 bars of pressure condition under synthesizing iron lithium phosphate nanometer powder.Compared with existing hydrothermal synthesis method, overcritical water law and the hot method of alcohol, the preparation method of above-mentioned lithium iron phosphate nano powder can be reacted under conditions of relatively low pressure, thus, because both can ensure that the security and economy of process without using high temp/high pressure reactor, and can is easily made the lithium iron phosphate nano powder that particle size and size distribution are controlled. |
