| titleOfInvention | Lithium metal negative electrode and preparation method thereof, and lithium secondary battery |
| abstract | The invention belongs to the technical field of negative electrode structures, and particularly relates to a lithium metal negative electrode, a preparation method thereof, and a lithium secondary battery. The lithium metal negative electrode of the invention includes a metal lithium body and a composite protective layer, the composite protective layer is arranged on at least one surface of the metal lithium body, and the material of the composite protective layer includes lithium fluoride and a lithiophilic metal element. Lithium fluoride can prevent electrons from being introduced into the electrolyte, so as to alleviate the problem of lithium dendrite growth in the electrolyte; the lithiophilic metal element has the property of dissolving Li, and when lithium ions are deposited on the surface of the lithium metal negative electrode, it can dissolve into the lithiophilic metal element In order to avoid the problem of dendrite nucleation caused by too fast local deposition of lithium ions, the formation of lithium dendrites can be avoided, and the cycle life of the battery can be improved. |
