PROBLEM TO BE SOLVED : To provide a method of manufacturing electrode material powder capable of easily inexpensively manufacturing nano-particles having uniform composition and high purity even if inexpensive LiOH is used, and to provide electrode material powder, an electrode, and a lithium battery.
SOLUTION : The method of manufacturing electrode material powder is that solution, dispersion, or suspension containing LiOH, source A (one kind or more selected from a group comprising Fe, Co, Mn, Ni, Cr, and Cu) and /or group B source (one kind of more selected from a group comprising Mg, Ca, Sr, Ba, Ti, Zn, B, Al, Ga, In, Si, Ge, Sc, Y, and rare-earth elements), phosphoric acid and/or a phosphate, a reaction inhibitor inhibiting reaction of LiOH and a phosphoric group, and a reaction retarder retarding reaction of the source A and the phosphoric group is sprayed in a high-temperature atmosphere to prepare a precursor, and the precursor is heat-treated. |
