Abstract: An electrolyte for a lithium-containing battery cell is described. The electrolyte includes a solvent having at least one carbonate ester, and at least one lithium salt having a concentration ranging from 3 mol/liter to 15 mol/liter in the solvent. The electrolyte also includes a diluent that includes an aromatic fluorocarbon. In some embodiments, the solution of the at least one lithium salt and the solvent is a supersaturated solution for at least some operating temperatures of the battery cell. Also described are lithium-containing battery cells that include a positive electrode, a negative electrode, and the electrolyte.

Abstract: A battery component is described that has at least one ceramic layer that includes ceramic particles and a binder. The ceramic particles may include α-alumina or γ-alumina. The ceramic layer may be characterized by a porosity of greater than or about 40 vol %. In additional embodiments, the one or more ceramic layers may have a weight ratio of ceramic particles to binder is greater than or about 90:10. The battery component may be a battery separator that is characterized by a MacMullin number of less than or about 40 and a thermal shrinkage of less than or about 1 vol. % after 1 hour at 140° C.
