| Summary: | With its distinctive multiple electrochemical reaction, iron vanadate (FeV<sub>3</sub>O<sub>9</sub>.2.6H<sub>2</sub>O) is considered as a promising electrode material for energy storage. However, it has a relatively low practical specific capacitance. Therefore, using the low temperature sol–gel synthesis process, transition metal doping was used to enhance the electrochemical performance of layered structured FeV<sub>3</sub>O<sub>9</sub>.2.6H<sub>2</sub>O (FVO). According to this study, FVO doped with transition metals with larger interlayer spacing exhibited superior electrochemical performance than undoped FVO. The Mn-doped FVO electrode showed the highest specific capacitance and retention of 143 Fg<sup>−1</sup> and 87%, respectively, while the undoped FVO showed 78 Fg<sup>−1</sup> and 54%. |
