The present disclosure is directed toward an electrodeposition-based dynamic glass element comprising an electrolyte that includes an aqueous solvent and an additive, wherein the electrolyte is stable over a temperature range that is greater than the stable temperature range of the aqueous solvent alone. In some embodiments, the freezing point of the electrolyte is lowered by its inclusion of the additive. Additives suitable for use in accordance with the present disclosure include alcohols, metal salts, sugars, cryoprotectants, and the like. In some cases, the freezing point of the aqueous-solvent-based electrolyte is lowered from 0&#xb0; C. to &#x2212;40&#xb0; C. by virtue of the inclusion of the additive. In some cases, the maximum stable temperature of the electrolyte is increased from 100&#xb0; C. to 110&#xb0; C. by virtue of the inclusion of the additive.

Dynamic windows comprising aqueous electrolytes having enhanced temperature stability

The present disclosure enables high contrast, fast, uniform, and color-neutral dynamic-glass elements based on uniform and reversible electrodeposition of metals a surface of the element. Elements in accordance with the present disclosure include a surface-modified transparent-conductor-based window electrode, wherein the surface modification of the window electrode includes a nucleation layer that is anchored to the transparent conductor via a non-metallic adhesion layer. In some embodiments, a plurality of traces is disposed on and electrically connected to the window electrode to reduce the voltage drop across the total area of the element, where the traces have a core made of a low-resistivity material.
