“…From Figure 6f, the CC@PANI NTs-H FSSC exhibits a high energy density from 21.9 Wh kg −1 (at the power density of 5.0 × 10 3 W kg −1 ) to 9 Wh kg −1 (at the power density of 1.2 × 10 4 W kg −1 ). The values are comparable with other congeneric FSSCs devices [31][32][33][34][35], as can be seen in Table 2. H FSSC exhibits a high energy density from 21.9 Wh kg −1 (at the power density of 5.0 × 10 3 W kg −1 ) to 9 Wh kg −1 (at the power density of 1.2 × 10 4 W kg −1 ).…”

Carbon materials have been widely used in designing supercapacitors (SCs) but the capacitance is not ideal. Herein, we synthesize polyaniline (PANI) nanotubes on the basis of a carbon cloth (CC) through a one-step self-degradation template method, and fabricate a CC@PANI NTs-H (CC@PANI nanotubes doping at high temperature) composite electrode by thermal acid doping. The CC@PANI NTs-H electrode obviously exhibits better electrochemical performance with a gravimetric capacitance of 438 F g −1 and maintains 86.8% after 10,000 cycles than the CC@PANI NTs-R (CC@PANI nanotubes doping at room temperature) electrode. Furthermore, we assemble a flexible solid state supercapacitor (FSSC) device with the as-prepared CC@PANI NTs-H composite electrodes, showing good flexibility and outstanding electrochemical performances with a high gravimetric capacitance of 247 F g −1 , a large energy density of 21.9 Wh kg −1 , and a capacitance retention of 85.4% after 10,000 charge and discharge cycles. Our work proposes a novel and easy pathway to fabricate low-cost FSSCs for the development of energy storage devices.

HIGHLIGHTS • Hierarchical porous reduced graphene oxide/poly(3,4-ethylenedioxythiophene)/polyaniline hybrid was designed. • The hybrid achieves a high capacitance of 535 F g −1 along with a good rate capability and cyclability. ABSTRACT 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.
