Abstract
The present disclosure relates to a cable type secondary battery which includes: a cable type electrode assembly including an inner electrode, a separator layer formed to surround the outer surface of the inner electrode and preventing a short-circuit between electrodes, and an outer electrode formed to surround the separator layer; a taping layer formed by spirally winding a sheet type tape so that it surrounds the outer surface of the cable type electrode assembly; and a packaging formed to surround the outer surface of the taping layer. According to the present disclosure, it is possible to prevent separation of the separator layer or the outer electrode, and thus to reinforce the bending characteristics of the cable type secondary battery.
