- Abstract
Supercapacitors (SCs) have attracted great scientific interest as competitive power sources for energy storage. In this work, we aim at preparing a high-performance anode material for SCs. With the goal of designing anode material with high specific capacitance, excellent rate capability, and long-term cycling stability, we prepared high-quality Mo-doped Fe3O4 nanoparticles decorated on rGO (MFO/G) composite with unique architecture as an innovative negative electrode material for SCs through a straightforward, economical, and scalable solvothermal technique. The thin rGO nanosheets-encapsulated MFO active sites interconnect with each other, which reduces the length of the ion diffusion path between the electrolyte and electrode, leading to enhanced electrochemical performance. Significantly, the MFO/G composite exhibited a maximum specific capacitance of 807 F g−1 at a current density of 1 A g−1, along with outstanding cycle life that retaining 85.5% of its primary capacitance following 10,000 successive cycles. The results demonstrate its promising prospects as an anode material for the advancement of high-performance energy storage devices.
