LITHIUM METAL NEGATIVE ELECTRODE AND METHOD OF MANUFACTURING THE SAME

A negative electrode for an electrochemical cell of a secondary lithium metal battery is manufactured by a method in which a precursor solution is applied to a major surface of a lithium metal substrate to form a protective interfacial layer thereon. The precursor solution includes a first organic solvent mixture, a dioxolane, and a fluorinated organosilane. The protective interfacial layer exhibits a composite structure including a polymeric matrix component and a lithium-containing dispersed component embedded in the polymeric matrix component.
