Electrochromic smart windows with co-intercalation of cations and anions for multi-band regulations.

ABSTRACT: Electrochromic technology has been considered as an energy-efficient approach to reduce the energy consumption in buildings and vehicles. Studies of electrochromic devices (ECDs) have so far focused mainly on control of cations (for example, H⁺, Li⁺, Na⁺, K⁺, and Zn²⁺, etc), while anions were rarely considered. Here, X-ray photoelectron spectroscopy (XPS) provides direct evidence that the transformation of Prussian blue (PB) to Prussian green (PG) occurs due to an anion intercalation process, in addition to the cation intercalation-induced switching between PB and Prussian white (PW). Co-intercalation of cations and anions is found in an ECD combining Nb₁₈W₁₆O₉₃ and PB as complementary electrochromic la
