ELECTROLYTIC SOLUTION AND LITHIUM METAL BATTERY CONTAINING THE SAME, BATTERY MODULE, BATTERY PACK, AND DEVICE

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 Cto Chydrocarbyls, where a substituent is selected from a phenyl, Cto Calkyls, or Cto Calkenyls. X is a sulfur atom or a phosphorus atom. Rand Reach 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 Rand Rare not oxygen atoms concurrently.
