Abstract

A method for manufacturing a positive electrode active material includes: (a) performing a first mixing process at a first shear rate to form a mixture of a lithium transition metal composite oxide and a graphene; and (b) performing a second mixing process at a second shear rate on the mixture, wherein (i) the first and the second mixing processes are performed using a mixer including a press head and a rotating chamber, and (ii) the second shear rate is greater than the first shear rate. Also disclosed is a positive electrode active material manufactured by the above method, and a rechargeable lithium battery including said positive electrode active material.
