    • The invention relates to an electrochromic (EC) device having oppositely arranged two EC electrode layers. The first EC electrode layer uses Prussian blue, osmium purple or ruthenium purple and accordingly takes on a characteristic color by electrochemical oxidation, and the second EC electrode layer uses a transition metal oxide which takes on a characteristic color by electrochemical reduction, such as WO.sub.3. The space between the two EC electrode layers is filled with an electrolyte solution. When an EC device of this type is left in the bleached state for some period of time and then driven for coloration, the density of coloration is insufficient because of a decrease in the quantity of electricity in the oxidizing and coloring reaction of the first EC electrode layer. The invention solves this problem by using, as the electrolyte solution, a solution of a lithium salt and a sodium salt in an organic solvent prepared such that Na.sup.+ ion amounts to 3-30 mol % of the total of Li.sup.+ ion and Na.sup.+ ion.
    • 本发明涉及具有相对布置的两个EC电极层的电致变色(EC)装置。 第一EC电极层使用普鲁士蓝,锇紫或钌紫,因此通过电化学氧化而呈现特征色,第二EC电极层使用通过电化学还原形成特征色的过渡金属氧化物,如WO3。 两个EC电极层之间的空间填充有电解质溶液。 当这种类型的EC装置处于漂白状态一段时间,然后驱动着色时,由于第一EC电极的氧化和着色反应中的电量减少,着色密度不足 层。 本发明通过将锂盐和钠盐的溶液用于制备成使Na +离子占Li +离子和Na +离子总数的3-30mol%而制备的有机溶剂中来解决这个问题。
