Positive electrode active material and non-aqueous secondary battery using the same

摘要

The present invention provides a positive electrode active material comprising: a positive electrode active material body; and at least one of oxide particles and carbon particles each having an average diameter of 1 mum or less; wherein at least one of oxide particles and carbon particles are adhered to a surface of the positive electrode active material body. I is preferable that a mass of the oxide particles adhered to the positive electrode material body is 0.001-2% of a mass of the positive electrode active material body. According to the above structure, there can be provided a positive electrode active material and non-aqueous secondary battery using the same capable of increasing a molding density (packing density) of the active material in a positive electrode, and capable of improving discharging rate characteristic of the battery by lowering an impedance of the electrode.
