A simple solution combustion method for the synthesis of V2O5 nanostructures for supercapacitor applications

“…2(iii)). It has been noted that different bands have been seen at 3476, 2427, 2341, 1644, 1426, 1337, 1167, 951, and 655 cm − 1 and are consistent with earlier results [17]. The O-H bond's stretching vibrations are indicated by the bands at 3476 cm − 1 , 2341 cm − 1 , and 2427 cm − 1 , while the bands at 1644 cm − 1 represent the bending vibration of the H-O-H bond.…”

“…This peak is caused by the sixfold coordination state of the V 5+ species. The absence of a signal at 470 nm, however, shows that there are no microcrystalline V 2 O 5 species present [17].…”

“…This shift is due to the electrode's sluggish intrinsic ohmic restriction or electrochemical kinetics [26,29]. At higher scan rates the electrodes show a poorer electrochemical performance with lower capacitances and lower material conductance [17,30]. This occurs due to the increase in interfacial tension and resistances, that bring lower electrolyte transport and an inadequate counter particle redox reaction [31].…”

“…This occurs due to the increase in interfacial tension and resistances, that bring lower electrolyte transport and an inadequate counter particle redox reaction [31]. The intercalation and deintercalation of K + cations from the electrolyte into the V 2 O 5 grid, indicate the pseudocapacitive characteristics of the electrodes, causing the sharp redox couplings within the applied potentials [17].…”

“…Nonetheless, the capacitance of V 2 O 5 falls short of expectations due to its poor solubility and specific surface area. As a result, researchers are continually investigating on various synthesis methods of V 2 O 5 nanomaterials [17].…”
