Core-Shell Structure of Polypyrrole Grown on V2O5 Nanoribbon as High Performance Anode Material for Supercapacitors

A core–shell structure of polypyrrole grown on V2O5 nanoribbons as a high performance anode material for supercapacitors is fabricated using anionic dodecylbenzenesulfonate (DBS−) as surfactant. Benefiting from the nanoribbon morphology of V2O5, the improved charge‐transfer and polymeric coating eff...

Zusammenfassung:A core–shell structure of polypyrrole grown on V2O5 nanoribbons as a high performance anode material for supercapacitors is fabricated using anionic dodecylbenzenesulfonate (DBS−) as surfactant. Benefiting from the nanoribbon morphology of V2O5, the improved charge‐transfer and polymeric coating effect of PPy, PPy@V2O5 nanocomposites exhibits high energy density, and excellent cycling and rate capability in K2SO4 aqueous electrolyte.
