| description | The invention relates to the technical field of lithium metal battery electrolyte materials, and provides a polymer electrolyte with a stable lithium ion deposition function and a preparation method and application thereof. In the polymer electrolyte, the hexafluorobutyl methacrylate HFBMA monomer can promote the formation of a fluorinated interface in the deposition process, the triazolyl methacrylate TBMA monomer can induce the formation of a nitrided interface in the deposition process, and the advantages of the fluorinated interface and the nitrided interface are played at the same time; and the effects of stabilizing lithium ion deposition and improving the interface stability between the electrolyte and the lithium metal are achieved. Compared with a traditional polymer electrolyte, the defect that a loose solid electrolyte interface film is formed in the deposition process of traditional electrolyte lithium can be effectively overcome, and the formed solid electrolyte interface film can inhibit side re |
