Abstract
A method for manufacturing a cable-type secondary battery includes: preparing a first polarity current collector having a long and thin shape; forming at least two first polarity electrode active material layers on the first polarity current collector to be spaced apart from each other in the longitudinal direction; forming an electrolyte layer to surround the at least two first polarity electrode active material layers; forming at least two second polarity electrode active material layers on the electrolyte layer to be spaced apart from each other at positions corresponding to the first polarity electrode active material layers; forming an electrode assembly by surrounding the second polarity electrode active material layers with a second polarity current collector; surrounding the electrode assembly with a cover member; and bending the electrode assembly and the cover member into a serpentine configuration with the active regions spaced apart from one another.
