Abstract

Abstract An Fe 3O [email protected] composite material has been successfully synthesized by a one-pot hydrothermal method without any templates and a sequential heat treatment process. X-ray diffraction, Raman spectrometry, scanning electron microscopy with energy dispersive spectroscopy, transmission electron microscopy and galvanostatic cell cycling have been used to characterize the structure and electrochemical performance of the as-prepared Fe 3O [email protected] composite. The electrode shows a stable and reversible capacity of over 600 mAh g −1 at a current of 53 mA g −1 for up to 60 cycles, which could be ascribed to the unique double-layer core–shell and embedded structures.
