Increasing Supercapacitor Features Using Reduced Graphene Oxide@Phosphorus

Supercapacitors have attracted much attention in the field of electrochemical energy storage. However, material preparation and stability limit their applications in many fields. Herein, a reduced graphene oxide@phosphorus (rGO@P) electrode was prepared using a simple inexpensive method. The new graphene structure (rGO@P) was characterized by X-ray di􀀀raction, Fourier transform infrared spectroscopy, scanning electron microscopy and Energy-dispersive X-ray spectroscopy. Electrode showed excellent performances (307 F g−1), which seem to be the highest among many other rGO@P-based electrodes reported so far. It also has an excellent cyclic stability up to 95% after 600 consecutive charge/discharge tests. So, the ease of the synthesis method and excellent performance of the prepared electrode materials mat have significant potential for energy storage applications.
