We report phosphatization is a promising method to enhance the performance of mesoporous TiO2 anode for lithium ion batteries. The resulting phosphated mesoporous TiO2 possessed higher reversible capacity and better cycling stability than the pure mesoporous TiO2. When cycled at 30 mA/g between 3.0 and 1.0 V, the initial capacity of phosphate mesoporous TiO2 was 249 mA h/g, significantly higher than that of pure mesoporous TiO2 (204 mA h/g). After 40 cycles, the capacity retention ratio of phosphate mesoporous TiO2 reached 83.7%, while pure mesoporous TiO2 had merely a capacity retention ratio...
