Growth of PANI thin layer on MoS2 nanosheet with high electro-capacitive property for symmetric supercapacitor

MoS2/polyaniline/functionalized carbon cloth electrode materials for excellent supercapacitor performance

“…4F , the S 2p spectrogram included two peaks of 167.8 eV (S 2p 3/2 ) and 169 eV (S 2p 1/2 ). Compared with the reported literatures, 28–30 there was a significant shift in the peak position of S 2p for MoS 2 , which may be caused by the oxidation process of MoS 2 . Furthermore, according to the Mo, S, C and N peak area results, the quantitative percentage of Mo, S, C and N can be calculated to be 7.20%, 4.13%, 71.6% and 18.9%, respectively.…”

“…The results could be due to the synergistic effects between PANI and MoS 2 , which facilitated charge carriers to transfer back and forth from MoS 2 nanosheet edges to inside and outside of PANI. 16,26 In addition, MoS 2 /PANI- x /FCC (MoS 2 /PANI-2/FCC, MoS 2 /PANI-5/FCC, MoS 2 /PANI-10/FCC, MoS 2 /PANI-15/FCC and MoS 2 /PANI-38/FCC) were tested by CV, and MoS 2 /PANI-10/FCC showed drastically enhanced current response, indicating that only a moderate amount ratio of PANI to MoS 2 can obtain the desirable capacitance.…”

“…14,15 However, two major defects are found in PANI pseudocapacitive materials, including low practical capacitance and poor cycle stability. 16,17 In addition, PANI electrode materials tend to cause a loss and unstable structural stability during the charge-discharge processes, resulting in poor supercapacitor performances, because the redox sites of the polymer backbone are not adequately stable and can be destroyed within a limited number of charge-discharge cycles. Therefore, numerous researchers focus on the architectural design of the multicomponent electrode materials to solve the above-mentioned problems.…”

An Aqueous Exfoliation of WO3 as a Route for Counterions Fabrication—Improved Photocatalytic and Capacitive Properties of Polyaniline/WO3Composite

“…Hence, the energy density value of 12.25 Wh kg −1 and the power density 1075.6 W kg −1 were obtained for a PANI/WO 3 -based supercapacitor. The Ragone plot shows the power and energy densities, compared with the reference values (see Figure 8 b) [ 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 ].…”

Mini-Review on Conducting Polymer–MoS2–Carbon Ternary Composite as a Hybrid Electrode Material for Supercapacitor Applications: Progress and Perspectives

“…Among a wide variety of active pseudocapacitive materials, polypyrrole, polyaniline, and PEDOT have gained significant interest due to their good environmental stability, doping–dedoping chemistry, good conductivity, ease of synthesis, etc. ; however, the mechanical degradation is an important factor that limits the electrochemical performance of a conducting polymer in many energy storage applications. − Supercapacitors have recently been combined with the layered structure molybdenum disulfide (MoS 2 ). − According to reports, the MoS 2 nanosheet can enhance the electrode materials’ capacitive qualities because of the high surface area for charge storage that its two-dimensional (2D) sheet-like structure can offer . More crucially, as compared to other transition metal oxide nanosheets, the MoS 2 nanosheet as a supporting material offers greater ionic conductivity and mechanical stability .…”
