摘要： 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.

摘要： A positive electrode material for a lithium secondary battery and a manufacturing method therefor are provided. The positive electrode material may have carbon nanotubes stably attached to a surface of an active material and may exhibit increased electron conductivity and improved surface stability. The positive electrode material for a lithium secondary battery may comprises: a positive electrode active material core comprising a Li—Ni—Co—Mn-M-O-based material, where M is a transition metal; and a carbon nanotube coating layer on a surface of the positive electrode active material core. Carbon nanotubes (CNT) may be in an amount of 1-5 wt %, based on 100 wt % of the positive electrode active material core.
