| description | The development of a simple and reliable strategy to synthesize cathode materials is crucial for achieving the overall high performance of rechargeable lithium batteries, which has proved to be quite challenging. Herein, we report a simple sol–gel method for the synthesis of Li<sub>2</sub>FeTiO<sub>4</sub> cathode materials. The reaction mechanism of Li<sub>2</sub>FeTiO<sub>4</sub> crystals can be divided into five stages: including the breakage of the coordination bond; the thermal decomposition of citric acid; the thermal decomposition of metal salts and the reduction of trivalent iron and the formation of Li<sub>2</sub>FeTiO<sub>4</sub> crystals. Finally, the optimum calcination temperature for the preparation of Li<sub>2</sub>FeTiO<sub>4</sub> cathode materials was explored. The Li<sub>2</sub>FeTiO<sub>4</sub> cathode material prepared at 700 °C provides a discharge-specific capacity of 121.3 mAh/g in the first cycle and capacity retention of 89.2%. Our results provide new insights into the application of Li<sub>2</sub>FeTiO<sub>4</sub> cathode materials. |
