Abstract

A reversible electrochemical mirror (REM) includes a first electrode and a second electrode, one of which is substantially transparent to at least a portion of the spectrum of electromagnetic radiation. An essentially nonaqueous electrolytic solution, disposed between the first and second electrodes, contains ions of an electrodepositable metal having a molar concentration of more than 0.5 M. the electrolytic solution also contains halide and/or pseudohalide anions having a total molar concentration ratio of at least 2:1 relative to the concentration of the electrodepositable metal cations. A negative electrical potential applied to the first electrode causes deposited metal to be dissolved from the second electrode into the electrolytic solution and to be electrodepotsited from the solution onto the first electrode to form a mirror deposit, thereby affecting the reflectivity of the REM device for electromagnetic radiation. A positive electrical potential applied to the first electrode causes deposited metal to be dissolved from the first electrode into the solution and electrodeposited from the solution onto the second electrode, thereby decreasing the reflectivity of the REM mirror. It is usually necessary to apply a surface modification layer to the first electrode to ensure uniform nucleation so that a mirror electrodeposit having high reflectivity is obtained. The high molar concentration of mirror metal cations attained in essentially nonaqueous solvents by use of at least a 2:1 molar ratio of halide and/or pseudohalide anions to electrodepositable metal ions in the electrolyte provides the fast switching speed, inherent electrolyte stability, high deposit quality, good deposit erasure and long cycle life needed for practical applications. Increases above this 2:1 molar ratio may be required to optimize the device performance.
