Abstract
Disclosed is a secondary battery with a non-aqueous electrolyte that has excellent cycle characteristics and output characteristics. Also disclosed is a positive electrode active material for a secondary battery with a non-aqueous electrolyte that includes a powder of a volume resistivity of 20 Ω·cm or more and 100 Ω·cm or less when said powder has a bulk density of 3 g/cm. The use of the lithium nickel composite oxide as a positive electrode active material can provide a secondary battery with a non-aqueous electrolyte that has excellent cycle characteristics and output characteristics.
