A uniform nitrogen-doped carbon coating layer is formed on Li4Ti5O12 particles by mixing porous Li4Ti5O12 powder with an ionic liquid and then treating the mixture at moderate temperature. Uniformly coated Li4Ti5O12 is shown to have significantly improved rate capability and cycling performance for Li-ion batteries. This relatively simple approach is versatile and can be extended to modify other electrode materials for electrochemical devices.
