lithium metal electrode; A positive electrode and an electrolyte interposed therebetween, wherein the electrolyte contains i) a high-resolution ether-based solvent capable of solvating lithium ions ii) a fluorine-substituted ether-based solvent represented by the following Chemical Formula 1 and iii) a lithium salt and a fluorine-substituted ether-based solvent represented by Formula 1 provides a lithium metal battery having a greater content than a high-resolution ether-based solvent capable of solvating lithium ions. [Formula 1] R-{O(CH 2 ) a } b -CH 2 -OC n F 2n H In Formula 1, R is C m F 2m H or C m F 2m +1 , n is an integer of 2 or more, m is an integer of 1 or more, a is an integer of 1 or 2, and b is 0 or 1. |
