CABLE-TYPE SECONDARY BATTERY

摘要

PURPOSE: A cable-type secondary battery is provided to ensure free deformation due to a linear structure and flexibility and to prevent the short by obstructing the direct contact between electrodes. CONSTITUTION: A cable-type secondary battery includes one or more negative electrodes, one or more positive electrodes, a secondary electrolyte layer(32), and a protective sheath(40). The negative electrode has the horizontal cross section of a predetermined shape. The negative electrode extends to the longitudinal direction and has a first electrolyte layer(31) which is the path of ions formed on the external side thereof. The positive electrode has the horizontal cross section of a predetermined shape and extends to the longitudinal direction. The secondary electrolyte layer enables the parallel arrangement of negative and positive electrodes and is the path of charged ions. The protective sheath is arranged in the circumference of the secondary electrolyte layer.
