In this study, bimetallic cobalt-vanadium-based layered double hydroxide (CoV-LDH) systems were developed by varying the Co/V molar ratios (1:1 and 2:1) hydrothermal temperatures (120 180 °C). Structural analysis X-ray diffraction (XRD), Raman, Fourier-transform infrared (FTIR) spectroscopy indicated successful formation of CoV-LDH with a unique structure lattice distortions, reflecting influence both metal concentrations temperature on crystal chemical structures systems. Similarly, field-emission scanning electron microscopy (FESEM) high resolution transmission (HRTEM) images revealed flaky 2D nanosheet-like for 1:1 ratio prepared at 120 °C (CVL1-120), whereas one-dimensional (1D) three-dimensional (3D) morphologies observed other different (2:1) and/or (180 Electrochemical performed in three-electrode setup demonstrated specific capacitance 314.4 F g-1 1 A current density CVL1-120, which is ∼4.5 5.2 times higher than those monometallic Co V-LDH, respectively. addition, CVL1-120 exhibited an excellent retention ∼97% over 5000 charge-discharge cycles 100% Coulombic efficiency 10 g-1. Furthermore, asymmetric device delivered energy 36.5 Wh kg-1 power 1208.2 W kg-1. This enhanced performance was attributed to its two-dimensional (2D) structures, rich intercalated ions serving as electroactive sites, facilitating charge storage improved stability, making it suitable electrode material sustainable supercapacitors.

Despite the numerous ongoing research studies in area of conducting polymer-based electrode materials for supercapacitors, implementation has been inadequate commercialization. Further understanding is required design and synthesis suitable like gels as supercapacitor applications. Among polymers, conductive polymer (CPGs) have generated great curiosity their use owing to attractive qualities integrated 3D porous nanostructures, softness features, very good conductivity, greater pseudo capacitance, environmental friendliness. In this review, we describe current progress on CPGs applications along with morphological behaviors thermal properties. We clearly explain approaches related phenomena, including electrochemical especially potential supercapacitors based these materials. Focus also given recent advances CPG-based electrodes performances CP-based promising composites CNT, graphene oxides, metal oxides discussed. This review may provide an extensive reference forthcoming insights into large-scale
