<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a positive electrode body for a nonaqueous electrolyte secondary battery capable of extracting sufficient electric capacity even when particle diameters of positive electrode active material particles are minute, and providing a nonaqueous electrolyte secondary battery improved in electric capacity. <P>SOLUTION: This manufacturing method of a positive electrode body for a nonaqueous electrolyte secondary battery includes processes of: providing a dispersion liquid by dispersing positive electrode active material powder, a conductive material and a binder in a solvent by using a high-speed shearing type disperser; providing a positive electrode mix by further executing a dispersion process to the dispersion liquid by using a high-pressure dispersant; and providing the positive electrode body by applying the positive electrode mix to one surface or both surfaces of a collector. <P>COPYRIGHT: (C)2010,JPO&INPIT |
