<P>PROBLEM TO BE SOLVED: To provide a method for producing, by use of a byproduct ferrous sulfate as a raw material, lithium iron phosphate which is finer and more uniform in particle diameter with high purity and high yield economically. <P>SOLUTION: The method for producing lithium iron phosphate comprises the steps of: mixing a lithium compound, a phosphate compound and water; and then adding, to the mixture, a byproduct ferrous sulfate whose titanium content is less than 1000 mg/kg, and whose calcium content is less than 500 mg/kg, thereby causing a hydrothermal reaction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
