摘要
Many hybrid electrodes for supercapacitors(SCs)are a reckless combination without proper structural design that keeps them from fulfilling their potential.Herein,we design a reduced graphene oxide/poly(3,4-ethylenedioxythiophene)/polyaniline(RGO/PEDOT/PANI)hybrid with hierarchical and porous structure for high-performance SCs,where components fully harness their advantages,forming an interconnected and conductive framework with substantial reactive sites.Thus,this hybrid achieves a high capacitance of 535 F g^−1 along with good rate capability and cyclability.The planar SC based on this hybrid deliver an energy density of 26.89 Wh kg^−1 at a power density of 800 W kg^−1.The linear SC developed via modifying a cotton yarn with the hybrid exhibits good flexibility and structural stability,which operates normally after arbitrary deformations.This work provides a beneficial reference for developing SCs.
