Abstract

A method for preparing a positive electrode active material includes: (1) pulverizing a carbon-based raw material to prepare carbon-based fine powder having an average particle diameter of about 10 nm to about 100 nm, (2) mixing a lithium metal composite oxide and the carbon-based fine powder to prepare a mixed powder, and (3) applying rotation of about 1,000 rpm to about 6,000 rpm for about 2 minutes to about 10 minutes to the mixed powder to form or provide a carbon-based coating layer on a particle surface of the lithium metal composite oxide Also disclosed are a positive electrode active material and a rechargeable lithium battery including the positive electrode active material.
