Abstract
Design of transparent mesh counter electrodes for use in dynamic window articles capable of reversible metal electrodeposition (RME). Such an RME window may include a transparent conductive electrode, an electrolyte in contact with the electrode, where the electrolyte includes metal cations that can be reversibly electrodeposited onto the electrode, and a mesh counter electrode. The mesh counter electrode includes an electrochemically inert core with a thin metal coating thereover. The thin metal coating can be of the material that is involved in electrodeposition (e.g., a combination of copper and bismuth). The mesh counter electrode is substantially transparent (e.g., transparency of at least about 70%). Such a mesh counter electrode can provide a high capacity (1.5 C/cm2) that provides good durability over numerous tinting and bleaching cycles, with minimal change in coloration efficiency, reflection profile, and electrodeposition metal concentration (e.g., [Cu2+]) in the electrolyte.
