<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing iron lithium phosphate with fine and uniform grain sizes and excellent discharge and charge characteristics of a secondary battery to be obtained in high purity and in high yield. <P>SOLUTION: The method for manufacturing iron lithium phosphate is characterized in that a reducing compound is added after mixing a lithium compound, a phosphoric acid compound and water so that an oxidation/reduction potential of the mixture in a reducing atmosphere is less than -1 mV, and then, a divalent iron compound is added and the mixture is subjected to hydrothermal reaction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
