摘要： A separator for an electrochemical device provided with a porous coating layer including multiple types of binder resins, and a method for manufacturing the same. The separator shows high adhesion between an electrode and the separator, even when any separate adhesive layer is not disposed on the surface of the separator. In addition, the separator shows higher adhesion to an electrode, as compared to a separator using a fluorinated binder resin, such as polyvinylidene fluoride, used conventionally in the art. Therefore, when introducing the separator to a battery, it is possible to manufacture an electrode assembly under a mild temperature and pressure condition, to improve the productivity of assemblage, to reduce defect generation, and thus to increase the yield. Further, the separator shows high affinity to an electrolyte, as compared to a semi-crystalline polymer, such as a fluorinated binder resin, and thus improves the output characteristics of a battery.
