Novel lead dioxide intercalated polypyrrole/graphene oxide ternary composite for high throughput supercapacitors

•Fabrication of ternary architecture of lead dioxide electrode.•Highly robust and stable electrode for advanced supercapacitors.•Superior device performance owing to the synergy of components. In this study, a novel polypyrrole (PPy)/reduced graphene oxide (rGO)/lead dioxide (PbO2) nanocomposite (PGPb) has been successfully fabricatedby a one pot cathodic electrodeposition methodfor the first time and characterized systematically. The fabricated electrode exhibited an enhanced electrochemical capacitance of 514 F g−1 and a capacitance retention of 86% even after 4000 cycles at a current density of 1 A g−1. The enhanced specific capacitance, rate capability, and cycling performance are ascribed to the rapid transferring path for electrons and ions and the structural integrity and stability endowed by synergy.
