Energy Storage & Supercapacitors

Supercapacitors with excellent power and reasonably high energy densities are becoming a perfect solution towards the recent demand of various energy storage applications. The present image is focused on introduced conductive materials into pseudocapacitive spinel ferrite to increase the performance of electrodes for supercapacitors. The one step, low-cost synthesis, and incorporation with high surface area conductive nanoarchitectures are developed based on CSs@CoFe2O4-based as novel electrodes for supercapacitors. The carbonization processing of CoFe2O4 nanoparticles featured and indicates high electrochemical capacitance (600 F/g at 1 A/g), high-performance rate, and cycling stability. By using CSs@CoFe2O4-based electrodes to assemble asymmetric supercapacitors device revealed high power density (750 W/kg) and energy density (27.08 Wh/kg) with long-term cycle stability with 99.33% retention of its initial capacitance, indicating the high potential of the fabricated materials for practical energy storage devices.
