摘要： The present invention provides an electrode comprising a current collector; an electrode active material layer formed on at least one surface of the current collector and comprising a mixture of electrode active material particles and a first binder polymer; and a porous coating layer formed on the surface of the electrode active material layer, comprising a mixture of inorganic particles and a second binder polymer and having a thickness deviation defined by the following Formula (1), and a manufacturing method thereof: T max - T min / T avg ‰¤ 0.35 wherein T max is a maximum thickness of the porous coating layer formed on the surface of the electrode active material layer, T min is a minimum thickness of the porous coating layer and T avg is an average thickness of the porous coating layer. The electrode of the present invention can be manufactured by the process of simultaneously drying the electrode active material layer and the porous coating layer, from which the binder polymers of the porous coating layer can be prevented from penetrating into the electrode active material layer so that the excellent qualities of the electrode can be achieved. In addition, uniform porous coating layer can be formed, which ensures the safety of the electrode.
