Cathode active material for lithium secondary battery, cathode for lithium secondary battery including the same and lithium secondary battery

Abstract

A cathode active material for a lithium secondary battery, a cathode for a lithium secondary battery including the same, and a lithium secondary battery are provided. The cathode active material for a lithium secondary battery includes: a first cathode active material including a lithium-nickel metal oxide in the form of a single particle; and a second cathode active material including lithium manganese iron phosphate. Accordingly, a lithium secondary battery with improved cell safety and high energy density per unit cell volume may be achieved.
