Overview

Synthesis boosts energy density to 15.8 Wh/kg in supercapacitors, indicating effective electrode material design.

Key Points

  • The optimized NiCoFeSe-2.25 electrode achieves a specific capacitance of 447.4 F g-1, demonstrating high performance.
  • After 5,000 cycles, the device retains 60.6% capacitance, indicating durability for energy storage devices.
  • Asymmetric supercapacitors deliver an energy density of 15.8 Wh kg-1 at a power density of 800 W kg-1, underlining efficiency.
  • Pseudocapacitive properties are enhanced through a simple selenization treatment of metal precursors.
