Abstract

A cable-type secondary battery includes an electrode assembly, which has a first polarity current collector having a long and thin shape, at least two first polarity electrode active material layers formed on the first polarity current collector to be spaced apart in the longitudinal direction, an electrolyte layer filled to surround at least two first polarity electrode active material layers, and at least two second polarity electrode active material layers formed on the electrolyte layer to be spaced apart at positions corresponding to the first polarity electrode active material layers, the electrode assembly being continuously bent into a substantially "S" shape by a space between the first polarity electrode active material layers; a second polarity current collector configured to surround at least one side of the electrode assembly bent into a substantially "S" shape; and a cover member configured to surround the second polarity current collector and the electrode assembly.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2010-0102968 filed in Korea on Oct. 21, 2010, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a cable-type secondary battery whose shape can be freely changed and a method for manufacturing the same. Background technique [0004] Recently, the development of wireless communication technology has contributed to the popularity of mobile devices. In response to the development of wireless communication technology, secondary batteries are basically used as power sources for mobile devices. Meanwhile, in order to prevent environmental pollution, electric vehicles, hybrid vehicles, etc. have been developed, and these vehicles are also driven by secondary batteries. [0005] Also, applications of secondary batteries have been increasing in various industrial fields, and their ou...
