Spinel Li4Ti5O12/C Composites as Potential Anode Materials of Lithium Batteries
Here the spinel Li4Ti5O12/C composites were prepared by a modified high temperature solid-state reaction. The as prepared Li4Ti5O12/C composites showed enhanced electrochemical lithium insertion performance in reversible capacity and rate capabilities. The improved electrochemical properties are attributed to the reduced grain size and the improved electronic conductivity caused by the pyrolytic carbon incorporated into the spinel Li4Ti5O12 particle. The spinel Li4Ti5O12/C composites with improved electrochemical properties may find versatile applications in various energy storage devices.
