Cable-type secondary battery |
摘要 |
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. |
