Energy-effective smart windows, mirrors, display devices, and automobile sunroofs
have been considered as applications of electrochromic materials. This chapter focuses
on the electrochromic behavior of Ti-based mixed metal oxides. Transition metal oxides
such as Titanium oxide (TiO2) have been used as promising electrochromic material
for this purpose since a smart window contains solid electrolyte and electrochromic
material layers (commonly metal oxide layers) sandwiched between transparent conductive
layers. However, relatively few publications studied the possible advantages (higher
colorization efficiency) of the mixtures of different metal oxides as electrochromic
material. This chapter aims to assess the results of investigations of Ti-based multicomponent
materials (TiO2-WO3, TiO2-V2O5, TiO2–MoO3, TiO2–SnO2) showing enhanced electrochromic
properties compared to the pure TiO2.
