Patent ID: 10290902

Abstract:
An electrolyte for a lithium metal battery, the electrolyte including: a solvated ionic liquid including a glyme solvent and a lithium salt, wherein an amount of the lithium salt is about 3 moles per liter or greater, and wherein a lithium metal battery including the electrolyte has an initial solution resistance of less than about 1 ohm and a bulk resistance of less than about 10 ohms. A lithium metal battery includes: a negative electrode including a lithium metal or a lithium metal alloy; a positive electrode; and the electrolyte. A method of manufacturing the lithium metal battery includes: mixing a glyme solvent and a lithium salt to obtain an electrolyte precursor; disposing the electrolyte precursor into the lithium metal battery; and performing hermetic immersion of the electrolyte precursor in the lithium metal battery to form the electrolyte.
