dc.description.abstractIn recent years, flexible and portable supercapacitor devices have become a focus of attention in the field of energy storage. However, challenges in the selection and preparation of appropriate electrode materials remain. The hierarchical constructing of conducting polymer@transition metal sulfide composites on the flexible carbon cloth substrate is an effective strategy to achieve high-performance supercapacitors. In here, highly conductive polythiophene (Pth) nanocone arrays are hierarchically constructed on the NiCo2S4 (NCS) coated carbon fiber cloth (CC). The modification of NCS electrode surface with conductive polythiophene (Pth) layer (about 6.21 S/cm) is based on a facile dip-coating process. This facile process allows the formation a conductive polythiophene (Pth) layer on the NCS nanoneedles by protecting porous NCS morphology. Pth shell not only increases the conductivity of NCS electrode but also alleviates agglomeration during charge-discharge process. The synergistic effect between NCS and Pth improves the capacitive characteristics of electrode. Compared to NCS@CC and Pth@CC electrodes, NCS@Pth(0.3)@CC composite electrode exhibits a superior specific capacitance (1632.8 F g−1 at 1 A g−1 of current density) and an outstanding retention stability (90.1 % after 5000 cycles). These impressive results emphasize the potential of the newly developed hybrid structure as a high-performance electrode material for electrochemical devices.
