发明名称 PROCESS FOR PRODUCING POSITIVE ELECTRODE ACTIVE MATERIAL PARTICLES FOR BATTERY
摘要 A process of producing positive electrode active material particles for a battery, comprising a step of providing a slurry comprising resin particles, a cationic surfactant and/or a polyvinyl alcohol derivative, lithium complex oxide particles, and a polar solvent; removing the polar solvent from the slurry to give a composition; and firing the composition and at the same time, removing the resin particles from the composition, wherein the cationic surfactant is a quaternary ammonium salt, the polyvinyl alcohol derivative is a polyvinyl alcohol into which a quaternary ammonium salt group has been introduced or which has been substituted by a quaternary ammonium salt group, and the resin particles have an average particle size of 0.1 to 20 µm.
