Abstract
Disclosed is a multilayer cable-type secondary battery including a first electrode assembly comprising one or more first inner electrodes and a sheet-type first separation layer-outer electrode complex spirally wound to surround outer surfaces of the first inner electrodes, a separation layer surrounding the first electrode assembly to prevent short circuit of the electrodes, and a second electrode assembly comprising one or more second inner electrodes surrounding an outer surface of the separation layer and a sheet-type second separation layer-outer electrode complex spirally wound to surround outer surfaces of the second inner electrodes.
