摘要： This application provides an electrolytic solution and a lithium metal battery containing the electrolytic solution. The electrolytic solution includes a lithium salt, an organic solvent, and an additive. The additive includes a sultam compound represented by Structural Formula I. R is selected from substituted or unsubstituted C1 to C10 hydrocarbyls, where a substituent is selected from a phenyl, C1 to C6 alkyls, or C1 to C6 alkenyls. X is a sulfur atom or a phosphorus atom. R1 and R2 each are independently selected from an oxygen atom, a fluorine atom, a chlorine atom, a bromine atom, and substituted or unsubstituted C1 to C10 hydrocarbyls. Both R1 and R2 are not oxygen atoms concurrently.

摘要： A lithium battery including an anode having an active anode material, a cathode having an active cathode material. The cathode material includes lithium nickel cobalt manganese cobalt oxide (NCM). An electrolyte separates the anode and cathode. The electrolyte includes a solvent or solvent mixture and lithium hexafluorophosphate, and a germanium organyl-based electrolyte additive. Also disclosed are uses of the germanium organyl-based electrolyte additive in the lithium battery for enhancing one characteristic selected from the group consisting of reversible capacity, Coulombic efficiency, cyclic stability and combinations thereof.
