CABLE TYPE SECONDARY BATTERY

摘要

A cable type secondary battery of the present invention comprises: an electrode assembly including first and second polarity electrodes in which an electrode active material is coated on a surface of a current collector having a circular cross section, an elliptical cross section, or a polygonal cross section perpendicular to the longitudinal direction thereof and which are thin and long, and a separation layer or an electrolytic layer which is inserted between the first and second polarity electrodes; and a cover member which can cover the electrode assembly, wherein a first polarity terminal connected to the first polarity electrode and a second polarity terminal connected to the second polarity electrode are formed at a first end of the cable type secondary battery, a housing cap is formed to fix the first polarity terminal and the second polarity terminal and to cover the first end of the cable type secondary battery, and a second end of the cable type secondary battery has a connecting means capable of adjusting the length thereof.
