Overview

Study shows improved electrochemical performance and capacitance in supercapacitors using N-doped graphene oxide and Fe2O3, highlighting benefits of porous structures.

Key Points

  • ASCs deliver high energy density of 25.3 Wh kg−1 at a power density of 205 W kg−1 when operated at 2 V.
  • Electrode materials include Fe2O3 and N-doped reduced graphene oxide, enhancing electrochemical performance by altering surface chemistry.
  • Synthesis involves a hydrothermal approach, resulting in stable composites that prevent parasitic reactions and enhance cyclic stability.
  • Stable configuration maintains 94% of initial capacitance after 10,000 charge-discharge cycles, indicating long-term reliability.
