An electrolyte for use in a commercially feasible rechargeable lithium metal battery is described. The electrolyte contains one or more lithium salts, one or more organic solvents, and one or more additives. This electrolyte allows reversible deposition and dissolution of lithium metal. Certain additives or combinations of additives dramatically improved cycle life, reduced cell expansion, and / or reduced cell impedance. [Selection] Figure 3 |
