Beschreibung
Zusammenfassung:	Provided is a positive-electrode material for nonaqueous-electrolyte secondary batteries, the positive-electrode material being capable of achieving both high capacity and high output when used for a positive electrode for nonaqueous-electrolyte secondary batteries. Also, provided is a method for manufacturing the positive-electrode material for nonaqueous-electrolyte secondary batteries, wherein a lithium metal composite oxide powder is mixed with lithium tungstate, the lithium metal composite oxide powder being represented by a general formula LizNi1-x-yCoxMyO2 (wherein 0.10≤x≤0.35, 0≤y≤0.35, 0.97≤z≤1.20, and M is an addition element and at least one element selected from Mn, V, Mg, Mo, Nb, Ti, and Al) and comprising primary particles and secondary particles composed of aggregation of the primary particles.
