Sonochemical Synthesis of Perovskite Embedded with Carbon Nanofibers as an Electrode Material for Energy Storage Application

The increasing depletion of non-renewable energy sources and the growing demand for rechargeable energy storage devices like pacemakers, consumer electronics, and biomedical devices demand high-performance materials in energy storage technologies. Herein we report the development of zinc titanate (ZTO)-based supercapacitor electrode material via a strategy of incorporating carbon nanofibers (CNF) as a scaffold composite material for enhanced energy storage performance. In the current work, the electrochemical performance for different ratios of ZTO/CNF-[1:1, 1:2 & 2:1] composites as electrode material for supercapacitors was examined. Among them, ZTO@CNF-1:1 has outsmarted other prepared materials with a high specific capacity of 199 mAhg −1 at 1Ag −1 . The fabricated asymmetric device (ZTO@CNF-1:1//AC), has delivered high specific capacitance of 92.8 Fg −1 at 1 Ag −1 , with high energy density of 18.56 Wh kg −1 , at a power density of 599.9 W kg −1 . The device also performed with an outstanding coulombic efficiency of 100% and capacitance retention of 110% after 10,000 cycles. This study provides insight into the potential of ZTO-based composites has electrode materials for energy-storage applications with high durability.
