Abstract: An electrode which has a Si-containing material layer and a porous film, and a lithium battery employing the same. In the electrode, the Si-containing material layer is applied on an electrode current collector and/or an electrode active material to protect the surface of the electrode current collector from oxidation. Also, the applied Si-containing material layer enhances the adhesion between the electrode current collector and the electrode active material to improve cycle life characteristics. Also, it increases the adhesion between the electrode active material and the porous film to reduce resistance, and to improve ohmic contacts and to lower the Shottkey barrier. In addition, the electrode includes the porous film functioning as a separator, and thus can provide a battery which is safe under conditions of overcharge and heat exposure without needing an additional separator.
