Electrochemical performance of flexible poly(ethylene terephthalate) (PET) supercapacitor based on reduced graphene oxide (rGO)/single-wall carbon nanotubes (SWNTs)

Journal Article


Abstract


  • The reduced graphene oxide (rGO)/single-wall carbon nanotubes (SWNTs) composites are deposited

    onto the poly(ethylene terephthalate)(PET) substrate using spray coating technique to fabricate a flexible

    supercapacitor. The electrochemical properties of the PETcomplete device as a function of bending cycles

    and angles are performed using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS)

    and galvanostatic charge/discharge tests. The EIS and charge/discharge curves of the flexible PET

    supercapacitor show good capacitive behavior even after prolonged bending cycles up to 500. The highest

    capacitance value obtains for the unbent PET supercapacitor is 42.2 F g1 (8.8 mF cm2

    ). The capacitance

    value of the PET supercapacitor is retained 75% after 500 bending with 6000th galvanostatic charge/

    discharge cycles.
