PURPOSE: A manufacturing method of positive electrode material of a lithium secondary battery is provide to omit lithium carbonate manufacturing process, and to manufacture positive electrode material of high quality with low cost. CONSTITUTION: A manufacturing method of positive electrode material comprises a step of preparing lithium concentrated solution, a step of manufacturing mixed solution by solving one or more kind of material selected from Co, Ni, Fe and Mn, and a step of synthesizing powder for positive electrode material by heat-spraying the mixed solution to a chamber. The lithium concentrated solution is lithium hydroxide aqueous solution in which lithium separated through electrolysis is concentrated. The heating temperature of the heat-spraying is 500-800 °C. |
