Reversible electro-optic device employing aprotic molten salts and method

摘要

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.
