| titleOfInvention | Method for coating modified ternary material by using carbon quantum dots |
| abstract | The invention belongs to the technical field of ternary materials, and particularly relates to a method for coating and modifying a ternary material by using carbon quantum dots. The method of the invention comprises the following steps: (1) taking cetyl pyridine chloride as a carbon source, and standing and reacting under excessive alkali liquor to generate carbon dots; (2) stirring the bare ternary material and carbon dots to obtain an active material, mixing the active material with a conductive agent and an adhesive, adding an organic solvent, rotating at a constant speed in a homogenizer, coating and drying a pole piece, and making a buckle to obtain the carbon quantum dot coated modified ternary material. Compared with non-coated carbon dot substances, the material prepared by the invention has the advantages that 1C/0.1C and 3C/0.1C are respectively improved to 90-98%, 80-90% and the like from 80-90% and 50-70%. In the high-temperature storage time examination, the thickness change rate of the film is reduced to below 3% after the film is stored for 7 days at 60 ℃ by 5-10%. The cyclic stability is discovered through examination, the cycle time can be increased to more than 2000 times by cycling 1000-1500 times at normal temperature, and the use requirement of the power battery is completely met. |
