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

• MIL-101(Cr) and MIL-101(Cr)/GO composites have been synthesized via a facile route.
• Synthesized composite materials were used as anode in lithium ion battery for the first time.
• The electrochemical performance MIL-101(Cr) was improved through doping GO.

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.

MIL-101(Cr)/graphene oxide composites have been successfully synthesized via a facile route using a solvothermal treatment. The morphology of GO reveals typical fold lamellar structure and MIL-101(Cr) is octahedral crystal morphology distributed uniformly with size about 1 μm. The graphene oxide dispersed uniformly over MIL-101(Cr). The rate performance confirmed the enhancement of GO doping on electrochemical performance.Figure optionsDownload as PowerPoint slide
