| description | The ion storage layer in electrochromic devices (ECDs) stores protons or lithium ions to provide electrochemical stability and extend cycle durability. This paper reports on the performance and stability of ECDs paired with various ion storage layers (NiO, V<sub>2</sub>O<sub>5</sub>, and IrO<sub>2</sub> films). The complementary ECD using a V<sub>2</sub>O<sub>5</sub> ion storage layer presented the fastest response time, but the lowest optical contrast. In addition, the ECD using an IrO<sub>2</sub> ion storage layer proved the most effective as an ion storage layer, due to its high optical modulation ability capability and long-term stability. Chronoamperometry analysis revealed that IrO<sub>2</sub>-based ECD (glass/IZTO/WO<sub>3</sub>/liquid electrolyte/IrO<sub>2</sub>/IZTO/glass) can be highly effective in modulating optical transmittance, as indicated by T = 61.5% (from T<sub>bleaching</sub> (69.6%) to T<sub>coloring</sub> (8.1%)) and switching times of 5.3 s for coloring and 7.3 s for bleaching at 633 nm. |
