<p>Lithium iron phosphate can be produced by a production method comprising: an aqueous solution provision step of providing an aqueous solution containing phosphoric acid and a hydroxycarboxylic acid; a first production step of adding iron particles containing 0.1 to 2 mass% of oxygen to the aqueous solution and then reacting the phosphoric acid and the hydroxycarboxylic acid in the aqueous solution with the iron particles under an oxidative atmosphere to produce a first reaction solution; a second production step of adding a lithium source to the first reaction solution to produce a second reaction solution; a third production step of adding a carbon source to the second reaction solution to produce a third reaction solution; a precursor production step of drying the third reaction solution to produce a lithium iron phosphate precursor; and a burning step of burning the lithium iron phosphate precursor under a non-oxidative atmosphere to produce lithium iron phosphate.</p> |
