| titleOfInvention | Preparation method of metal lithium cathode and lithium iron phosphate battery |
| abstract | The invention provides a preparation method of a lithium metal cathode and a lithium iron phosphate battery, which comprises the following steps: (1) dispersing an aluminum salt and a lithium salt in an organic solvent to obtain a mixed solution of the aluminum salt, the lithium salt and the organic solvent; (2) and (2) soaking the pretreated lithium metal sheet in the solution obtained in the step (1) for a period of time, taking out and drying to obtain the lithium metal cathode. According to the invention, the lithium metal sheet is soaked in the solution formed by the aluminum salt and the lithium salt to form a layer of protective film on the surface of the lithium metal sheet, so that the uniform deposition of lithium can be obviously stabilized, and the formation of lithium dendrite is favorably inhibited. In addition, the preparation process is simple, easy to regulate and control, the used equipment is conventional equipment, the raw materials are easy to obtain, the cost is low, and the preparation method is safe and pollution-free and is suitable for large-scale production. |
