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

Abstract

A cathode active material for a lithium secondary battery includes first lithium metal phosphate particles, second lithium metal phosphate particles having an average particle diameter (D50) smaller than an average particle diameter (D50) of the first lithium metal phosphate particles and including manganese, and lithium-transition metal oxide particles having an average particle diameter (D50) larger than the average particle diameter (D50) of the first lithium metal phosphate particles and including nickel. A secondary battery include the cathode active material for a lithium secondary battery.
