Claim Text:
1. A printed energy storage device comprising: a first electrode; a second electrode; and a separator positioned between the first electrode and the second electrode, at least one of the first electrode and the second electrode comprising an ionic liquid, wherein the ionic liquid includes a cation selected from the group consisting of 1-ethyl-3-methylimidazolium, butyltrimethylammonium, 1-butyl-3-methylimidazolium, 1-methyl-3-propylimidazolium, 1-hexyl-3-methylimidazolium, choline, ethylammonium, tributylmethylphosphonium, tributyl(tetradecyl)phosphonium, trihexyl(tetradecyl)phosphonium, 1-ethyl-2,3-methylimidazolium, 1-butyl-1-methylpiperidinium, diethylmethylsulfonium, 1-methyl-3-propylimidazolium, 1-methyl-1-propylpiperidinium, 1-butyl-2-methylpyridinium, 1-butyl-4-methylpyridinium, 1-butyl-1-methylpyrrolidinium, and diethylmethylsulfonium, wherein the ionic liquid includes an anion selected from the group consisting of tetrafluoroborate, tris(pentafluoroethyl)trifluorophosphate, trifluoromethanesulfonate, hexafluorophosphate, tetrafluoroborate, ethyl sulfate, dimethyl phosphate, methansulfonate, triflate, tricyanomethanide, dibutylphosphate, bis(trifluoromethylsulfonyl)imide, bis-2,4,4-(trimethylpentyl) phosphinate, iodide, chloride, bromide, and nitrate, wherein the at least one of the first electrode and the second electrode comprises a zinc salt, and wherein an anion of the zinc salt is the same as the anion of the ionic liquid.
