| titleOfInvention | A composite metal lithium negative electrode and its preparation method and application |
| abstract | The invention belongs to the technical field of lithium batteries, and specifically discloses a composite metal lithium negative electrode and a preparation method and application thereof. The negative electrode comprises a three-dimensional carbon-based current collector with a porous structure, and a metal attached to the surface of the three-dimensional carbon-based current collector and in the internal pores. Lithium, and a protective film covering metal lithium; the protective film includes a lithiophilic metal and a lithium salt, and the lithiophilic metal is a metal that can be reduced and replaced by lithium metal; the composite metal lithium negative electrode is in the first charge and discharge process with the electrolysis The liquid reacts to form a stable solid electrolyte phase interface, and the solid electrolyte phase interface will not decompose during subsequent charge and discharge processes. The three-dimensional carbon-based current collector, lithiophilic metal and lithium salt in the composite metal lithium negative electrode of the invention play the roles of relieving the volume strain of the negative electrode, inducing uniform deposition of lithium and forming a stable SEI film on the surface of the negative electrode, and the preparation method is simple, practical and cost-effective. Low, it is used in metal lithium secondary batteries, which can greatly improve the cycle life of the battery and improve the battery performance. |
