© 2024 Elsevier B.V.In this study, the plain MoO3 and Ag-doped MoO3 nanorods are anchored on a flexible fibrous carbon cloth using a hydrothermal method, and their performances are thoroughly evaluated by fabricating the supercapacitors using both types of nanorods. The doped substrate shows drastic enhancement in specific capacitance which is nearly four times greater than undoped MoO3 nanorods at a current density of 0.5 mA/cm2. Additionally, the Ag doped MoO3 shows an excellent energy density of 43 µWh/cm2. The superior performance of the doped nanorods is attributed to its pseudocapacitive behaviour, higher conductivity, and improved charge kinetics at the electrode–electrolyte interface, enabling a more efficient and potential supercapacitor-based energy storage system to drive future low power flexible and wearable electronic devices.
