Abstract Supercapacitor's demand for hybrid vehicles, portable electronic gadgets, and high‐power applications is increasing unexpectedly. However, supercapacitors′ inadequacies (i. e., inflated costs, poor energy density, erratic cycle life) need to be addressed by introducing novel composite materials developing facile synthesis techniques which can give them high surface area improved electrochemical stability. Moreover, supercapacitor electrodes based on ternary composites should designed broaden their application range deal with the challenges. The primary aim of this review explore recent advances in field supercapacitors address challenges field. Specifically, we have focused nanocomposites comprising Graphene‐Conducting Polymers‐Metal Oxides (G‐CPs‐MOs) Sulfides (G‐CPs‐MSs). Our investigations centred around exploring various techniques, morphology analysing reported evaluations highlight potential prospects they present.

This work reports the preparation and testing of a composite material composed α-Manganese dioxide (α-MnO2) coated with polyaniline (PANI) reduced graphene oxide (rGO) for supercapacitor application. The structure morphology materials were characterized by using X-ray diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), thermogravimetric analysis (TGA) Raman spectroscopy. electrochemical performances investigated cyclic voltammetry (CV), Galvanostatic charge–discharge (GCD), stability impedance (EIS). α-MnO2-coated PANI/rGO nanocomposite exhibited specific capacitance 261 F g−1 at scan rate 5 mV s−1 75% retention after 2000 cycles A g−1. It showed energy 11 W h kg−1 power 1250 kg−1.

Supercapacitors (SCs) are attractive as promising energy storage devices because of their distinctive attributes, such high power density, good current charge/discharge ability, excellent cyclic stability, reasonable safety, and low cost. Electrode materials play key roles in achieving performance these SCs. Among them, binary transition metal sulfides (BTMSs) have received significant attention, attributed to conductivity, abundant active sites, electrochemical properties. This topic review aims summarize recent advances principles, design, evaluation the for nanostructured BTMSs (including nickel–cobalt sulfides, zinc–cobalt copper–cobalt sulfides.) nanocomposites those carbon nanomaterials, oxides, polymers). Nanostructuring well effects on were discussed, including nanoparticles, nanospheres, nanosheets, nanowires, nanorods, nanotubes, nanoarrays, hierarchitectured nanostructures. Their has further been reviewed specific capacitance, rate capability, cycling stability. In addition, hybrid supercapacitors (HSCs) assembled using cathodes also summarized compared. Finally, challenges prospects HSCs-based BTMS electrodes presented.
