Patent number: 8343388Abstract: Disclosed are an electrode having a porous active coating layer, a manufacturing method thereof and an electrochemical device containing the same. The electrode having a porous active coating layer according to the present invention may be useful to enhance peeling and scratch resistances of the porous active layer and improve a lamination characteristic toward the porous active layer by introducing a porous active layer onto a porous substrate having pores, the porous active layer having heterogeneity of morphology toward a thickness direction in which a content ratio of the binder polymer/inorganic particles present in a surface layer is higher than that of the binder polymer/inorganic particles present inside the surface layer. Accordingly, the stability and performances of the battery can be improved at the same time since the detachment of the inorganic particles from the porous active layer may be reduced during the assembly process of the electrochemical device.Type: GrantFiled: March 6, 2007Date of Patent: January 1, 2013Assignee: LG Chem, Ltd.Inventors: Sang-Young Lee, Seok-Koo Kim, Jong-Hyeok Park, Jang-Hyuk Hong, Byoung-Jin Shin
