Abstract

A single-compartment reversible mirror device having a solution of aprotic molten salt, at least one soluble metal-containing species comprising metal capable of being electrodeposited, and at least one anodic compound capable of being oxidized was prepared. The aprotic molten salt is liquid at room temperature and includes lithium and/or quaternary ammonium cations, and anions selected from trifluoromethylsulfonate (CF3SO3−), bis(trifluoromethylsulfonyl)imide ((CF3SO2)2N−), bis(perfluoroethylsulfonyl)imide ((CF3CF2SO2)2N−) and tris(trifluoromethylsulfonyl)methide ((CF3SO2)3C−). A method for preparing substantially pure molten salts is also described.
