<P><B>Abstract</B></P> <P>A new structure for a switchable mirror device based on reversible electrodeposition is proposed. This device does not contain Cu ions in the electrolyte and adapts a counter electrode. The feasibility of the device was evaluated with a WO<SUB>3</SUB> film, which is a well-known electrochromic material, as a counter electrode. Even in the absence of Cu ions, the WO<SUB>3</SUB> film facilitates a clean erase feature in the device. Furthermore, using a pre-deposited Ag film as a working electrode, Ag deposition can be driven at a substantially lower voltage than that in conventional devices. Moreover the deposition current decreases with the progress of Ag deposition, and stops after completion of the deposition process. The results clearly indicate that the tri-bromine ion, which makes the self-erasing circulation, is not generated during Ag deposition process. The new switchable mirror shows excellent bistability and size scale-up is possible because it does not consume continuous current in the mirror state. By appling the proposed technology, a switchable mirror device with a 7cm × 9cm active area was successfully fabricated.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Cu-free switchable mirror device based on reversible electodeposition was developed. </LI> <LI> Counter electrode material was introduced to the device for the first time. </LI> <LI> Bistability was dramatically improved by application of pre-deposited Ag film. </LI> <LI> The device has low self-erasing current and has potential for scale-up. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
