An electrode including a current collector; an electrode active material layer on a surface of the current collector and including internal pores; an inner coating layer filled in the internal pores of the electrode active material layer and including an adhesive material; and an outer coating layer disposed on a surface of the electrode active material layer and including an adhesive material. A total weight of the inner coating layer and the outer coating layer per area of one surface of the current collector is about 0.1 g/mto about 0.7 g/m. In addition, the electrode active material layer has a porosity of about 13% to about 16% in a cross section having a depth of about 20 μm from the surface of the electrode active material layer to the current collector.
