CABLE-TYPE SECONDARY BATTERY

摘要

PURPOSE: A cable type secondary battery is provided to prevent the deintercalation of active material, to be easily deformed, and to maintain the stability and excellent performance of a secondary battery. CONSTITUTION: A cable type secondary battery comprises: a negative electrode current collector(10) having a predetermined shape, and expanded along longitudinal direction, a negative electrode active material pattern layer(20) formed to be separated each other of negative electrode active material patterns with constant gaps on the outside of the negative electrode current collector; an electrolyte layer(30) which surrounds the negative electrode active material pattern layer, for being the path of charged ions; a positive electrode active material pattern layer(40) formed to be separated each other of positive electrode material patterns with constant gaps on the outside of the electrolyte layer; and a positive electrode current collector surrounding the outside of the positive electrode active material pattern layer.
