| titleOfInvention | A kind of preparation method of carbon quantum dot modified LiFePO4 cathode material |
| abstract | The invention discloses a method for preparing a carbon quantum dot modified LiFePO4 positive electrode material, which belongs to the field of preparation methods for lithium ion battery positive electrode materials. A method for preparing a carbon quantum dot modified LiFePO4 positive electrode material uses chitosan as a carbon source , to modify and modify the surface of lithium iron phosphate with carbon quantum dots, using a two-step method of microwave ultrasound combined with hydrothermal carbonization to modify the surface of lithium iron phosphate with carbon quantum dots, the preparation method is simple, and the prepared material has a uniform particle size , the distribution is uniform, and the material has a large specific surface area; and carbon quantum dots can expose more active sites on the surface of lithium iron phosphate, providing more space for lithium ion storage, and at the same time better improve the efficiency of iron phosphate The conductivity of lithium has excellent rate performance. In addition, the self-sterilizing magnetic stirrer with a safety disinfection cover used in the production process can disinfect the reaction environment inside the container and improve the safety of the operator during the production process. |
