NOVELTY - An iron source compound, lithium source compound and phosphorus source compound are dispersed in water or mixture of water and organic solvent in the mole ratio of 0.5-1.0:0.8-1.3:1.0. The obtained solution is spray dried after adding carbon source additive in hot air to obtain precursor powder. The precursor powder is roasted in reducing atmosphere comprising argon gas and nitrogen or hydrogen to obtain positive electrode material.    USE - Manufacture of positive electrode material for lithium ion battery. Uses include but are not limited to mobile telephone, uninterrupted power supply, notebook computer, camera, portable electric tool, electronic instrument and electric car.    ADVANTAGE - The positive electrode material is manufactured with improved productivity using inexpensive raw material. The electrode material provides batteries with high specific cavity and cycle performance.    DETAILED DESCRIPTION - An iron source compound, lithium source compound and phosphorus source compound are dispersed in water or mixture of water and organic solvent in the mole ratio of 0.5-1.0:0.8-1.3:1.0. The obtained solution is spray dried after adding carbon source additive in hot air to obtain precursor powder. The precursor powder is roasted in reducing atmosphere comprising argon gas and nitrogen or hydrogen to obtain positive electrode material. The iron source compound is ferric nitrate, ferric hydroxide, ferric oxide, ferric chloride, ferrous chloride, iron acetate, iron oxalate, ferrous sulfate and/or ferrous ammonium sulfate. The lithium source compound is lithium carbonate, lithium chloride, lithium hydroxide and/or lithium nitrate. The phosphorus source compound is phosphoric acid, ammonium dihydrogen phosphate, ammonium phosphate and/or lithium hydrogen phosphate. The carbon source additive is inorganic carbon source additive or organic carbon source additive. The inorganic carbon source additive is chosen from graphite powder, carbon black powder and acetylene black. The organic carbon source additive is polyethylene glycol, glucose, sucrose, cyclodextrin, glutin, citric acid, polyvinyl alcohol and/or starch. The volume ratio of water and organic solvent is 1:0.05-3.0.
