Synthesis of Gadolinium Molybdate via Sonochemical Method and Its Application in Supercapacitor Electrode Modification

ABSTRACT In this study, gadolinium molybdate (Gd 6 MoO 12 ) was successfully synthesized via a sonochemical method and explored for its potential application as an electrode modifier in supercapacitors. This work allowed the synthesis of a supercapacitor electrode that is both chemically stable and has a high capacity. A lower‐loss option suitable for prolonged use without replacement has been developed as a substitute for current energy storage devices. The synthesized material was characterized and evaluated for its performance as a modifier for supercapacitor electrodes, demonstrating promising electrochemical properties. For the sake of this, the material's capacity was assessed at various current densities and cyclic stability measurements for ultralong cycles. For sample 1Ag −1 , the capacity was measured 156.27 Fg −1 and for 1000 cycles the cycling stability measured 26.37% (at 1Ag −1 ) and for 10,000 cycles the cycling stability measured 143.36% (at 10Ag −1 ). These results demonstrate a noticeable decline in capacity with decreasing current values, indicating the material's behavior and electrochemical performance under varying current conditions. As concluding remarks, obtained using sonochemical methods, will be a noteworthy study in literature due to its specific capacitance value and cycle life.
