CATHODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY |
摘要 |
Disclosed herein is a cathode active material based on lithium nickel-manganese-cobalt oxide represented by Formula 1, wherein the lithium nickel-manganese-cobalt oxide has a nickel content of at least 40% among overall transition metals and is coated with a conductive polymer at a surface thereof. A lithium secondary battery having the disclosed cathode active material has advantages of not deteriorating electrical conductivity while enhancing high temperature stability, so as to efficiently provide high charge capacity.
