1. A battery, comprising:
an intercalation anode comprising a material selected from the group consisting of a carbon compound, a silicon compound, a titanium compound, a molybdenum compound, and combinations thereof;
an electrically conductive cathode current collector;
a cathode comprising an active material comprising a metal halide, wherein the metal halide is incorporated into the electrically conductive cathode current collector, and wherein the metal halide comprises an alkali metal or alkaline earth metal and a halogen;
an electrolyte solution comprising (i) at least one selected from the group consisting of a substituted cyclic carbonate compound, a non-substituted cyclic carbonate compound, a substituted non-cyclic carbonate compound, and a non-substituted non-cyclic carbonate compound, and (ii) an ion-conducting salt comprising a metal cation [M]+ and an anion [X]− having a chemical formula of [M]+[X]−, wherein [M]+ is selected from the group consisting of Li+, Mg2+, Zn2+, Al3+, Na+, and combinations thereof, and [X]− is selected from the group consisting of nitrate (NO3−), hexafluorophosphate (PF6−), tetrafluoroborate (BF4−), bisoxalato borate (BOB−), difluorooxalato borate (DFOB−), trifluoromethanesulfonate (TF−), trifluoromethanesulfonylimide (TFSI−), fluorosulfonylimide (FSI−), and combinations thereof; and
an oxidizing gas in contact with the intercalation anode, the cathode, and the electrolyte,
wherein the metal halide of the cathode comprises a selection from the group consisting of (i) a metal ion selected from the group consisting of Li+, Mg+, Na+, and combinations thereof; and (ii) a halide ion selected from the group consisting of I−, Br−, Cl−, F−, and combinations thereof.
