Abstract
A positive electrode includes a positive electrode active material layer including a positive electrode active material, a conductive material, and a binder, wherein the positive electrode active material contains any one among Li(Nix1Mny1Coz1)O2 (0.55<x1<0.69, 0.15<y1<0.29, 0.15<z1<0.29, x1+y1+z1=1) and Li(Nix2Mny2Coz2)O2 (0.75<x2<0.89, 0.05<y2<0.19, 0.05<z2<0.19, x2+y2+z2=1) and the conductive material contains a carbon nanotube, and when the positive electrode active material is Li(Nix2Mny2Coz2)O2, the positive electrode active material layer satisfies Relation 1 and when the positive electrode active material is Li(Nix2Mny2Coz2)O2, the positive electrode active material layer satisfies Relation 2:0.0020×<0.0050×  [Relation 1]0.0015×<0.0044×  [Relation 2]
