An electro-optic element having enhanced durability by the addition of an additive. The additive may enhance the durability of the electro-optic element by reducing or eliminating the effects of water on species with the electro-optic element, such as the electrolyte. Specifically, the additive may operate to reduce or eliminate the formation and/or accumulation of hydrogen fluoride within the electro-optic element by interaction of the electrolyte with water or alcohol molecules. In some embodiments, the additive may be an organosilicon species, such as (3-cyanopropyl) dimethylfluorosilane.
