“…Such an electrochemical performance of the N-doped V 4 C 3 /C electrode is found to be better when compared with that of other vanadium-based electrodes reported in some recent literature studies. 38–40…”

“…Such an electrochemical performance of the N-doped V 4 C 3 /C electrode is found to be better when compared with that of other vanadium-based electrodes reported in some recent literature studies. [38][39][40] The electrochemical behavior of the as-synthesized material was further corroborated by the electrochemical impedance spectroscopy (EIS) test. Fig.…”

“…The assembled ASC exhibits an energy density of 21.4 W h kg −1 at a power density of 225 W kg −1 and could retain 6.1 W h kg −1 delivering a maximum power density of 4.5 kW kg −1 , which are found to be better than the energy-power density values reported recently for several other ASCs as summarized in Table S2. † [38][39][40][51][52][53]56,57 We have also calculated the power density using the maximum power transfer theorem where the ASC could deliver an energy density of 21.4 W h kg −1 at a power density of 9.6 kW kg −1 and 6.1 W h kg −1 at a maximum power density of 17.2 kW kg −1 as demonstrated in Fig. S24.…”

Design, synthesis and application of two-dimensional metal tellurides as high-performance electrode materials

“…Telluride has a substantially greater electrical conductivity and is projected to perform better electrochemically compared with other materials, leading to the widespread research and advancement of metal tellurides built into diverse nanostructures for supercapacitor (SC) applications ( Liu et al, 2017b ; Rathore et al, 2022 ). Kim et al created silver-decorated NiFe alloy telluride nanorods (AMMT HNRs) on nickel foam (NF) ( Figure 6A ) ( Jayababu et al, 2021 ).…”

Redox-Guided Synthesis of Au–V2O5–MnO2 Nanoflower Composites with Enhanced Electrical Conductance for Supercapacitor Applications

“…Recently, research on energy storage materials became very popular due to the large energy consumption of mankind and decreasing sources of fossil fuels. − In the field of energy storage, various vanadium-based material like vanadium phosphates, , vanadium chalchogenides, and vanadium oxides have gained much attention due to their wide working potential window in three- and two-electrode assemblies. Among them, vanadium oxides like V 2 O 5 are the most popular due to their valence structure, which consists of five electrons, , and they can partially or entirely participate in a redox-mediated reaction.…”
