Disclosed herein are electrodes having a multi-layered structure, including at least two active material layers formed on an electrode current collector or including at least two active material layers formed on an electrode current collector, wherein at least two active material layers are stacked thereon, and a supercapacitor comprising the same. The electrodes including at least two active material layers configured of the activated carbon layer having large specific surface area and the graphene layer having excellent electrical conductivity in order to reduce the internal resistance and stacked in a multi layered structure are manufactured and the supercapacitor includes the electrodes to increase capacitance due to the large specific surface area of the activated carbon and reduce the internal resistance due to excellent electrical conductivity of the graphene, thereby making it possible to improve the capacitance and electrical conductivity. |
