Publisher: | SPRINGER HEIDELBERG | Abstract: | In the present study, we report the synthesis of Fe@Ag nanoparticles/2-aminoethanethiol functionalized reduced graphene oxide (rGO) composite (Fe@AuNPs-AETrGO) and its application as an improved anode material for lithium-ion batteries (LIBs). The structure of the Fe@AgNPs-AETrGO composite was characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS). The electrochemical performance was investigated at different charge/discharge current rates by using CR2032 coin-type cells and cyclic voltammetry (CV). It was found that the spherical Fe@AuNPs were highly dispersed on the rGO sheets. Moreover, the Fe@AuNPs-AETrGO composite showed high specific gravimetric capacity of about 1500 mAh g(-1) and long-term cycle stability. | URI: | https://hdl.handle.net/11499/22199 https://doi.org/10.1007/s11581-015-1520-1 |
