Nonaqueous electrolyte positive electrode active material for a secondary battery, a method of manufacturing the same, the positive electrode active material for a non-aqueous electrolyte secondary battery positive electrode using, and a non-aqueous electrolyte secondary battery using the positive electrode

Even when you save the battery at high temperature, by a lithium-transition metal composite oxide and the electrolyte can be inhibited from gas generated by the reaction, it improves the reliability of the battery, and a lithium transition metal by suppressing the composite oxide is degraded, and its object is to provide a positive active material for a nonaqueous electrolyte secondary battery capable of achieving a reduction suppression of battery capacity. Compound consisting of zirconium and elemental fluorine, a positive electrode active material adhering to the surface of the lithium cobalt oxide, the positive electrode active material, while stirring the lithium cobalt oxide, the solution cobaltate containing zirconium and a fluorine It can be prepared by spraying the lithium.
