Increasing Supercapacitor Features Using Reduced Graphene Oxide@Phosphorus

Supercapacitors have attracted much attention in the field of electrochemicalenergy storage. However, material preparation and stability limit their applications inmany fields. Herein, a reduced graphene oxide@phosphorus (rGO@P) electrode wasprepared using a simple inexpensive method. The new graphene structure (rGO@P) wascharacterized by X-ray di􀀀raction, Fourier transform infrared spectroscopy, scanningelectron microscopy and Energy-dispersive X-ray spectroscopy.Electrode showed excellent performances (۳۰۷ F g−۱), which seem to be the highestamong many other rGO@P-based electrodes reported so far. It also has an excellentcyclic stability up to ۹۵% after ۶۰۰ consecutive charge/discharge tests. So, the ease ofthe synthesis method and excellent performance of the prepared electrode materials mathave significant potential for energy storage applications.
