REVERSIBLE ELECTROCHEMICAL MIRROR (REM) WITH IMPROREVERSIBLE ELECTROCHEMICAL MIRROR (REM) WITH IMPROVED ELECTROLYTIC SOLUTION VED ELECTROLYTIC SOLUTION

摘要

A reversible electrochemical mirror (REM) includes a first electrode (106) a nd a second electrode (110), one of which is substantially transparent. An electrolytic solution (112), disposed between the first and second electrode s, contains ions (116) of a metal which can electrodeposit on the electrodes depending on the applied potential. The electrolytic solution also contains halide and/or pseudohalide anions having a total molar concentration ratio o f at least 6:1 compared to that of the electrodepositable metal. It is usually necessary to apply a surface modification layer (108) to the firs electrode to ensure uniform nucleation so that a mirror electrodeposit having high reflectivity is obtained.
