Abstract
The present invention relates to an elastic fiber electrode including a hybrid fiber prepared by coating a carbon nanotube sheet on a polymer fiber, in which the hybrid fiber is in a yarn form having a coiled structure, and the carbon nanotube sheet makes a wrinkled surface, and a coil- or spring-type elastic fiber electrode manufactured by coiling a hybrid nanofiber prepared by coating a carbon nanotube sheet on a polymer fiber has excellent mechanical and electrical properties. In particular, the elastic fiber electrode has increased porosity by depositing manganese dioxide on a surface thereof, thereby enhancing electrochemical performance. Thus, a micro-supercapacitor using the elastic fiber electrode has high current density and excellent capacitance retention, may maintain the electrochemical characteristics even after being subjected to various deformations, such as bending, coiling, or weaving, and has high elasticity and reversible behaviors, thus providing stable capacitance.
