“…Figure a shows the X-ray diffraction (XRD) pattern for the rGO 1 , rGO 1 -THBA 1:1, rGO 1 -THBA 1:2, rGO 1 -THBA 1:3, and rGO 1 -THBA 1:4. The diffraction peak (002) for rGO 1 occurs at around 2θ = 23.5°, which is in line with the typical peak of graphite . The distinct broadened peak for the rGO 1 -THBA is shown at about 2θ = 21.6°, corresponding to a d -spacing of 4.1 Å which is slightly larger than that of rGO 1 (3.8 Å) .…”

An organic molecular electrode (OME) is obtained, in which the polyhydric organic molecules (3,4,5-trihydroxybenzamide, THBA) act as a guest molecule to decorate graphene hydrogel (rGO1). The THBA acts as a spacer to prevent the rGO sheet from aggregation and provides an active center for OME. In the three-electrode configuration, the prepared OME (rGO1-THBA) presents a capacitance of 390.6 F g–1 and has a capacitance retention of 73.7% even when the scanning rate increases from 5 to 100 mV s–1. Furthermore, we synthesize an organic molecule 1,4,5,8-naphthalenetetracarboxylic diimide (NDP) and immobilize it onto the rGO surface to form another OME (rGO-NDP) as the counter electrode. An all-carbon asymmetric supercapacitor (rGO1-THBA//rGO-NDP: ASC) is constructed by using rGO1-THBA and rGO-NDP as the positive and negative electrodes, respectively. The resultant device achieves a capacitance of 70.8 F g–1 and delivers an energy density of 14 W h kg–1, supplying the power of 590 W kg–1. More importantly, the two asymmetric devices in series connection are able to light up 24 LED lights for 100 s.

“…For GOPG, it exhibits a new peak at 2θ = 10.2°, which can be attributed to (001) diffraction of GO. 32 By comparison, HGOPG presents a similar XRD pattern with a slightly increased 2θ for (001) diffraction, revealing a smaller interlayer distance of HGOPG (0.85 nm) than that of GOPG (0.87 nm). This result implies an intimate contact between PANI/graphene composite and holey graphene oxide being favorable for the electrode performance.…”

“…Because the overlap with the peak of PANI, the characteristic peak of graphene (2θ = 26°) cannot be observed. For GOPG, it exhibits a new peak at 2θ = 10.2°, which can be attributed to (001) diffraction of GO . By comparison, HGOPG presents a similar XRD pattern with a slightly increased 2θ for (001) diffraction, revealing a smaller interlayer distance of HGOPG (0.85 nm) than that of GOPG (0.87 nm).…”

“…Table S5 compares the specific capacitance, rate performance and cycling ability of the current work with those of previously PANI-based composite electrodes, such as AgCl intercalated RGO-PANI, 32 graphene/PANI, 51 RGO/C-PANI, 52 PANI/MHCF/CF, 53 and 20%-GO@MSNs/PANI. 54 It can be found that the holey graphene/PANI/graphene nanohybrid in this work displays a relatively high specific capacitance, an ultrahigh-rate retention and a comparable cycling performance.…”

Hierarchically porous holey graphene/PANI/ graphene nanohybrid is fabricated by adopting a facile twostep process in which PANI/graphene hybrid was first synthesized hydrothermally and then wrapped with a layer of holey graphene. The resulted sandwich-like structure cannot only promote electronic transmission and ionic diffusion, but also contribute to a prominent rate capability. A symmetric supercapacitor was assembled with the obtained holey graphene/PANI/graphene nanohybrid, exhibiting a maximum specific capacitance of 437 F•g −1 at 1 A•g −1 , an energy density of 55 Wh•kg −1 at 900 W•kg −1 , an ultrahigh-rate performance (retained 43% capacitance at 100 A•g −1 ), as well as a long-term life (84% retention after 5000 loops at 10 A•g −1 ). The present work may provide an insight for designing highperformance symmetric supercapacitor.

“…It is due to the fact that during multiple charge and discharge processes, the intercalation/deintercalation of ions will cause the volume of PANI to expand and shrink, then damage the physical structure of the active material, resulting in a decrease in specific capacitance and cycle performance. 46 –48 PANI-80 retained about 82% of its initial capacitance after 1000 charge–discharge cycles, which shows the best performance among all the samples. This observation is consistent with the CV and GCD tests.…”

Polyaniline nanowires (PANI NWs) were synthesized under different temperatures through a facile hydrothermal method and used as electrodes for high-performance pseudocapacitor. The resulting samples were analyzed by X-ray diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy, scanning electron micrographs, thermogravimetric analysis, and X-ray photoelectron spectroscopy. Electrochemical properties of these PANI electrodes are studied by cyclic voltammetry, galvanostatic charge–discharge test, and electrochemical impedance spectroscopy in 0.5M H2SO4 aqueous solution. The highest specific capacitance is obtained on the PANI NWs synthesized under 80°C (PANI-80) with 540.0 F g−1 at current density of 0.5 A g−1 accompanied with 82% specific capacitance retention after 1000 charge discharge cycles at 5 A g−1 current density.
