A lithium metal negative electrode incorporates a solid-electrolyte interphase (SEI) with distinct inorganic and organic layers, alongside an electrolyte containing a specialized additive. The inorganic layer, close to the lithium metal, may contain Li—F and Si—F bonds, while the organic layer may include carbon- and oxygen-containing CxOy or Si—C. The additive is defined by formulas involving a metal positive ion, Si, and trimethylsilyl groups, and may enhance cycling stability by forming a uniform SEI that suppresses lithium dendrite formation. When combined with an ether-based solvent, the additive can be present in amounts from about 0.1 to about 50 parts by weight of the electrolyte. The resulting battery exhibits high coulombic efficiency, reduced overvoltage, and retains at least 80% of its initial capacity after 100 charge-discharge cycles at a rate of 1C or higher, thus offering improved performance and longevity for lithium secondary battery applications.
