摘要
The present invention relates to a positive electrode active material for a non-aqueous electrolyte secondary battery, and more particularly, Li 2 Ni x M a O 2 (wherein M is an element selected from the group consisting of Al, Si, P and Ga, x + a = 1 , 0 a? 0.1.). The lithium-nickel composite oxide may be used alone or in combination with a conventional lithiated transition metal oxide material as a cathode active material for a secondary battery of a non-aqueous electrolyte.;The positive electrode active material according to the present invention, when applied to a non-aqueous electrolyte secondary battery, provides a lithium ion reservoir or extra lithium ion source suitable for overcoming the irreversible capacity loss typically encountered in current lithium ion batteries. .
