Abstract

Abstract : A novel strategy to design a high performance fiber-shaped PEDOT@MnO2 //C@Fe3 O4 asymmetric supercapacitor with excellent flexibility for wearable electronics. Abstract : Fiber-shaped supercapacitors, which are energy-storage devices that feature flexibility and wearability, could realize further gains in energy-storage performance if their electrodes are properly designed. Herein, we present a high energy-performance and flexible fiber-shaped supercapacitor by using PEDOT@MnO2 and C@Fe3 O4 composites as the positive and negative electrodes, respectively. The as-fabricated fiber-shaped supercapacitor with a high working voltage of 2 V exhibits a high areal specific capacitance of 60 mF cm −2 and a large energy density of 0.0335 mW h cm −2 . This fiber-shaped supercapacitor exhibits good flexibility and particularly can be deformed without energy-performance decay. Furthermore, this fiber-shaped supercapacitor woven into a wristband in series can successfully power a LED, indicating its promising practical application in wearable electronics.
