Abstract

Provided is a method of manufacturing a cathode active material for a lithium secondary battery. The method of manufacturing a cathode active material for a lithium secondary battery includes mixing a transition metal macro precursor and a lithium precursor to prepare a preliminary lithium-transition metal composite oxide particle; calcining the prepared preliminary lithium-transition metal composite oxide particle; and pulverizing the calcined preliminary lithium-transition metal composite oxide particle to form lithium-transition metal composite oxide particle. Accordingly, the process may be easily performed and a single crystal cathode active material having a uniform size may be manufactured.
