Claim 14:
15. A lithium-containing battery cell comprising:
a positive electrode;
a negative electrode; and
a lithium-containing electrolyte, wherein the lithium-containing electrolyte comprises:
a solvent comprising at least one carbonate ester;
at least one lithium salt having a concentration ranging from 3 mol/liter to 15 mol/liter in the solvent, wherein the at least one lithium salt is supersaturated in the solvent;
