“…The R ct value for the GO-Pd/PS electrode is smaller than the other electrodes. Furthermore, the large Warburg region (the straight line at low frequency) of these electrodes shows the greater variations in ion diffusion path lengths and an increased barrier against ion movement [33]. Due to the high diffusion length of ions in Si wafer-based electrode, a significant reduction in the capacitance of the electrode was observed.…”

“…For instance, incorporation of the third component, say, graphene or conducting polymer or CNTs component to MnO 2 (first component) and conducting polymer or graphene system or porous nanocarbons (second component) have markedly upgraded the overall capacitance and cyclic stability through modifications in the electrical conductivity, contact interactions, porosity, electrochemical surface activities besides improving the mechanical flexibility, etc. of the resultant ternary nanocomposite electrodes relative to the corresponding MnO 2 /conducting polymer or MnO 2 /graphene or MnO 2 /CNTs binary electrode systems respectively [161–212] …”

Manganese dioxide (MnO2) has proved itself as a popular pseudocapacitive material with low fabrication cost, high availability, low toxicity, and improved handling safety compared to many other inorganics or carbon‐based systems existing in the market. However, the specific capacitance reported to date has been far inferior to that of the theoretically predicted value (ca. 1370 Fg−1), which is mainly attributed to the issues associated with poor conductivity, nanostructure agglomeration, low porosity, rapid electrolyte‐mediated dissolution, and so forth, which have considerably limited its commercial effectiveness. Thus, to bring about improvement in the electrochemical performance of MnO2‐based supercapacitors, novel designs of MnO2 nanomaterials through composite formations with other substances, such as nanocarbons, conducting polymers or inorganic materials, namely metal oxides and sulfides, have been comprehensively explored. Extensive studies on these MnO2 binary nanocomposites revealed significant improvement in the electrochemical features compared to pristine phases; nevertheless, the achieved state is still far below practicability. Hence, scientists have opted for MnO2‐based ternary nanocomposites achieved by blending appropriate proportions the three components (MnO2 nanostructures being one of the constant components) that would promote synergism to attain suitable dimensions, crystallinity, crystal structure, conductivity, mass loading, and electrolyte selectivity so as to confer superior capacitance, charge transfer kinetics, better utilization of electroactive materials, energy and power densities, as well as improved mechanical stability and environmental adaptability. Herein, recent developments and advancements in the research of various MnO2‐based ternary nanocomposites employed for supercapacitor applications have been discussed and are compared with binary analogs with special emphasis on correlating their composition, morphology, and the electrochemical properties that are noticeably modified upon introduction of the third component. The associated challenges encountered in their progress toward commercialization and the probable ideas of persuading better strategic designs of these ternary systems for high‐performance supercapacitor applications have also been delineated.

A new composite from graphene quantum dots (GQDs) and NiFe layered double hydroxide was successfully prepared by the coprecipitation method under optimal conditions. The nanoparticles of the composite were analyzed by X-ray diffraction (PXRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and thermal gravimetric analysis (TGA) to obtain the structure, composition and morphology information. Also, the electrochemical properties were investigated by cyclic voltammetry, galvanostatic charge/ discharge measurements, and electrochemical impedance spec-troscopy. The nanocomposite displays a specific capacitance of 712.7 F g À 1 and excellent cycle life after 2500 cycles by applying 10 A g À 1 of the current density in 1 M KOH electrolyte, which confirms that the nanocomposite has superb capacitance retention (~94.8 %) and can be used as a capable supercapacitor. Furthermore, this study provides a desirable procedure for the preparation of novel nanocomposites based on graphene quantum dots, which can be used in energy storage/ conversion devices.
