Overview

Demonstrates high-performance energy storage in supercapacitors using a novel electrode design, suggesting enhanced application possibilities.

Key Points

  • The aim is to develop a hybrid electrode using PANI, ZnO, and rGO for improved supercapacitor performance.
  • Constructed a hybrid electrode with PANI, ZnO, and rGO.
  • Evaluated electrochemical performance through charge-discharge tests and cyclic voltammetry.
  • Analyzed cycling stability with 10,000 cycles and impedance characteristics.
  • Achieved capacitance of 295 F g−1 at 1 A g−1 and 310 F g−1 at 10 mV s−1.
  • Exhibited 68% capacitance retention at increased current density, indicating excellent rate capability.
  • Demonstrated a high energy density of 27 Wh kg−1 at 250 W kg−1 and great cycling stability with 92% capacitance retention after 10,000 cycles.
