Article Synopsis
- Complementary electrochromic devices (ECDs) are used in smart windows but struggle with stability due to issues like ion-trapping and charge mismatches between their electrodes.
- This study presents a new design with a partially covered nickel oxide (NiO) and platinum (Pt) counter electrode, which stabilizes performance and addresses charge imbalance.
- The improved device shows impressive performance metrics, including 68.2% optical modulation, rapid color change times, and the ability to endure 10,000 cycles, making it a promising solution for practical applications.
Proton and Redox Couple Synergized Strategy for Aqueous Low Voltage-Driven WO Electrochromic Devices.
ACS Appl Mater Interfaces
June 2023
Aqueous electrolytes possess non-combustible and eco-friendly features compared to organic electrolytes, leading them to be more suitable for application in smart windows for daily use. However, limited by the narrow electrochemical window of water (1.23 V), its use in conventional electrochromic devices (ECDs) would result in irreversible performance loss, which arises from decomposition caused by high voltage.
