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. پرونده مقاله
