摘要:
A cathode active material for a lithium secondary battery according to an embodiment of the present disclosures a plurality of composite particles, each of which comprises a lithium metal phosphate particle, and a carbon coating formed on at least a portion of a surface of the lithium metal phosphate particle. A standard deviation of thickness values of the carbon coating measured by an X-ray photoelectron spectroscopy (XPS) for five different composite particles of the plurality of composite particles is 15 nm or less.
