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 (CF.sub.3
SO.sub.3.sup.-), bis(trifluoromethylsulfonyl)imide ((CF.sub.3
SO.sub.2).sub.2 N.sup.-), bis(perfluoroethylsulfonyl)imide ((CF.sub.3
CF.sub.2 SO.sub.2).sub.2 N.sup.-) and tris(trifluoromethylsulfonyl)methide
((CF.sub.3 SO.sub.2).sub.3 C.sup.-). A method for preparing substantially
pure molten salts is also described.
Um dispositivo reversível do espelho do único-compartimento que tem uma solução do sal derretido aprotic, ao menos uma espécie metal-contendo do soluble que compreende o metal capaz de ser electrodeposited, e ao menos um composto anodic capaz da oxidação foi preparado. O sal derretido aprotic é líquido na temperatura de quarto e inclui o lítio e/ou cations do ammonium quaternary, e os anions selecionados do trifluoromethylsulfonate (CF.sub.3 SO.sub.3.sup. -), bis(trifluoromethylsulfonyl)imide ((CF.sub.3 SO.sub.2).sub.2 N.sup. -), bis(perfluoroethylsulfonyl)imide ((CF.sub.3 CF.sub.2 SO.sub.2).sub.2 N.sup. -) e tris(trifluoromethylsulfonyl)methide ((CF.sub.3 SO.sub.2).sub.3 C.sup. -). Um método para preparar sais derretidos substancialmente puros é descrito também.
