PURPOSE: A liquid electrolyte for a lithium metal battery is provided to form a stable protection film and to prevent the formation of dendrite, and to improve the electrochemical performance of the battery. CONSTITUTION: A liquid electrolyte for a lithium metal battery comprises a lithium salt and a non-aqueous organic solvent including 1,3,5-trioxane, 1,3-dioxsolane, and fluorine-based cyclic carbonate. The amounts of the 1,3,5-trioxane, the 1,3-dioxolane, and the fluorine-based cyclic carbonate are respectively 5-60 vol%, 10-80 vol%, and 5-30 vol%, based on the total weight of the non-aqueous organic solvent. A lithium metal battery includes a positive electrode; a negative electrode including at least one selected from a lithium metal and a lithium alloy; and the liquid electrolyte.
