| titleOfInvention | Method for preparing carbon-coated nano-lithium titanate by ethylene diamine tetraacetic acid-citric acid (EDTA-CA) joint complexation |
| abstract | The invention discloses a method for preparing carbon-coated nano-lithium titanate by ethylene diamine tetraacetic acid-citric acid (EDTA-CA) joint complexation. Pure Li4Ti5O12 is prepared by a sol-gel method and an EDTA-CA dual chelator joint complexation method; and a Li4Ti5O12/C anode material is obtained by performing further carbon coating. The lithium titanate particles prepared by the method have a good dispersion effect; and a particle aggregation phenomenon is remarkably improved. The prepared Li4Ti5O12/C has high charging and discharging specific capacity and stable cycle performance; at room temperature, when the ratio is 1C, the initial discharging capacity of the Li4Ti5O12/C reaches 174.5 mAh/g which is close to the theoretical capacity; and when the ratio is 10C, the discharging capacity of the Li4Ti5O12/C reaches over 140 mAh/g. Moreover, the Li4Ti5O12/C has stable cycle performance, and has a wide application prospect in the field of civil portable electronic equipment and power equipment. |
