Graphene oxides doped MIL-101(Cr) as anode materials for enhanced electrochemistry performance of lithium ion battery

Abstract MIL-101(Cr)/graphene oxides composites has been successfully synthesized via a facile route using a solvothermal treatment and fully characterized using powder X-ray diffraction (PXRD), scanning electron microscope (SEM), thermal gravimetric analysis (TGA) and infrared spectroscopy (IR). The specific capacity of MIL-101(Cr)/GO are almost twice larger than that of MIL-101(Cr) at the first discharge process and the multiple relationship maintained over 40 cycles, indicating that the electrochemical performance of MIL-101(Cr) as anode material has been improved through doping by GO.
