We developed GO(graphene oxide)/CNT-PEDOT:PSS(poly(3,4 ethylenedioxythiophene): poly(styrene sulfonate)) hybrid core-shell fibers for energy storage application by enhancing the wettability of CNT fiber and proved the feasibility of undemanding wet-spinning and mass production. The resultant hybrid fibers exhibit superior performance in terms of fiber type supercapacitor by showing high capacitance (~113 F/cm3) as well as negligible voltage drop (0.124 V at 30 A/cm3 in 5.5 cm ). Furthermore, the self-fusion capability of PEDOT:PSS moiety enabled the retention of hybrid-fiber-twisted yarn structures as well as the improvement of electrochemical capacitance, thus, stored energy density.
