A positive electrode includes a current collector and a positive active mass layer on the current collector. The positive active mass layer includes a positive active material, active carbon, a conductive material, and a binder. The active mass density of the positive active mass layer and the thickness of the positive active mass layer satisfy Equation 1. 0.09≰active mass density of the active mass layer(g/cc)/thickness of the active mass layer(μm)≰0.3 Equation 1 |
