| titleOfInvention | Method for preparing nano-lithium titanate cathode material |
| abstract | The invention discloses a method for preparing a nano cathode material of a lithium ion battery at a low cost. A basic structural formula of the cathode material of the lithium ion battery is Li4Ti5O12 with a cubical spinel structure. The method is characterized by comprising the following steps of (1) sufficiently mixing a lithium salt precursor, TiO2 and a carbon precursor in a water, aqueous solution or solvent environment to obtain a precursor suspension; (2) grinding the precursor suspension; (3) drying the precursor suspension to obtain a precursor mixture; (4) carrying out calcinations on the precursor mixture in an inert atmosphere or inert and air atmosphere; and (5) smashing and grading the clacinated product to obtain a Li4Ti5O12 cathode material or Li4Ti5O12/C composite cathode material. The Li4Ti5O12 cathode material and the Li4Ti5O12/C composite cathode material have excellent electrochemical performance. The invention also provides a nano-electrochemically active cathode material with low cost and uniform particle size distribution produced by the method, and electrodes and batteries manufactured by the nano-electrochemically active cathode material. |
