Original Abstract Submitted
A positive electrode material for a lithium secondary battery has improved electron conductivity and surface stability because oxidation-treated carbon nanotubes are stably attached to the surface of an active material. According to one embodiment the positive electrode material includes a positive electrode active material core made of a Li—Ni—Co—Mn-M-O-based material (M=transition metal) and an oxidized carbon nanotube coating layer formed on the surface of the positive electrode active material core and including 1% to 3% by weight of oxidation-treated carbon nanotubes (OCNT) relative to 100% by weight of the positive electrode active material core.
