NOVELTY - A composite metal oxide sintered component is obtained by subjecting slurry containing metal oxide, metal compound and solvent to spray-granulation process, heat-treating the obtained granulation component at plus minus 200 degrees C based on decomposition temperature of metallic compound, and baking the heat-treated granule components. The heat treatment of granulation component is carried out by thermal insulation process. The metal oxide is chosen from a group containing transition metal oxide, and metal oxide of 3B, 4B and 5B elements of periodic table.    USE - Composite metal oxide sintered component is used for positive electrode active material for nonaqueous electrolyte secondary battery (both claimed) such as lithium secondary battery used as power supply for electronic device such as notebook personal computer, electronic book player, digital versatile disk player, portable audio player, portable television, mobile telephone, cordless power tool, electric vehicle, hybrid car and fuel-cell vehicle.    ADVANTAGE - The composite metal oxide sintered component is manufactured efficiently, and has excellent moldability. The positive electrode active material formed using composite metal oxide sintered component has excellent high-rate discharging characteristics.    DETAILED DESCRIPTION - A composite metal oxide sintered component is obtained by subjecting slurry containing metal oxide, metal compound and solvent to spray-granulation process, heat-treating the obtained granulation component at plus minus 200 degrees C based on decomposition temperature of metallic compound, and baking the heat-treated granule components. The heat treatment of granulation component is carried out by thermal insulation process. The metal oxide is chosen from a group containing transition metal oxide, and metal oxide of 3B, 4B and 5B elements of periodic table. The metallic compound is chosen from alkali metal compound and alkaline-earth metal compound. The metal oxide and metallic compound are slightly soluble in the solvent. The metallic compound contains nonmetallic element component which desorbs during thermal insulation process. An INDEPENDENT CLAIM is included for manufacture of composite metal oxide sintered component.    DESCRIPTION OF DRAWING(S) - The drawing shows the chart illustrating X-ray diffraction of sintered component. (Drawing includes non-English language text)
