The article does not address any potential challenges or limitations that may arise during the manufacturing process of the positive electrode material with oxidation-treated carbon nanotubes.
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.
