Abstract: The present invention provides a cable-type secondary battery comprising an inner electrode which includes at least one first polarity electrode having a first polarity current collector with a long and thin shape, whose cross-section perpendicular to its longitudinal direction is a circular, oval or polygonal form; a first polarity electrode active material layer formed on an outer surface of the first polarity current collector; and an electrolyte layer filled to surround the first polarity electrode active material layer, and at least one wire-type second polarity electrode which wholly surrounds the inner electrode and is winding around the exterior thereof.Thus, the inventive cable-type secondary battery provided with an outer winding electrode has excellent flexibility to prevent the release of the active material.

Abstract: A separator for an electrochemical device. The separator includes a porous substrate made of a porous polymer film having an excellent compressibility and permanent strain. The porous substrate has excellent physical strength and durability, and ensures a high breakdown voltage while using a heat resistant layer having a small thickness, and thus shows a low possibility of short-circuit generation. In addition, the separator may further include a heat resistant layer including inorganic particles, on the surface of the porous substrate. It is possible to further improve the compressibility, maximum compressibility and permanent strain characteristics depending on the types of inorganic particles.
