Abstract
An electrolyte, an electrochemical cell including the electrolyte, and a battery including the electrochemical cell are disclosed. Exemplary electrolytes allow for electrochemical cells and batteries with relatively high efficiency and stability that can be charged to relatively high voltages.
Claims20
A lithium-metal electrochemical cell comprising:
- a first electrode;
- a second electrode, wherein lithium metal is reversibly electrochemically deposited during charging of the lithium-metal electrochemical cell;
- a separator disposed between the first electrode and the second electrode;
- and
- an electrolyte comprising:
- one or more first solvents, wherein each of the one or more first solvents is selected from the group consisting of low-coordinating solvents and non-polar solvents;
- one or more second solvents, wherein each of the one or more second solvents is a coordinating solvent;
- and
- one or more lithium salts in an amount of greater than 5 moles per liter of the one or more second solvents,
- wherein the electrolyte comprises about 3 to about 65 wt. % of the one or more first solvents.
