Abstract
Provided is a cable-type secondary battery including an anode current collector having a horizontal cross section of a predetermined shape and extending longitudinally, an anode active material pattern layer having anode active material patterns spaced away at a predetermined interval on the anode current collector, an electrolyte layer surrounding the anode active material pattern layer and serving as an ion channel, a cathode active material pattern layer having cathode active material patterns spaced away at a predetermined interval on the electrolyte layer at locations corresponding to those of the anode active material patterns, and a cathode current collector surrounding the cathode active material pattern layer. The cable-type secondary battery having the active material patterns has excellent flexibility to prevent the active material from falling off from the active material layer.
