This study introduces a novel NiO-Pt counter electrode for complementary electrochromic devices (ECDs), significantly improving cycling stability and overcoming charge mismatch issues for practical smart window applications.

Area of Science:

  • Materials Science
  • Electrochemistry
  • Nanotechnology

Background:

  • Complementary electrochromic devices (ECDs) using WO3 and NiO electrodes are vital for smart windows.
  • Poor cycling stability due to ion-trapping and charge mismatch hinders practical ECD applications.

Purpose of the Study:

  • To enhance the stability and overcome charge mismatch in complementary electrochromic devices.
  • To introduce a partially covered NiO-Pt counter electrode (CE) within an electrochromic electrode/Redox/catalytic counter electrode (ECM/Redox/CCE) structure.

Main Methods:

  • Assembled an ECD with a WO3 working electrode and a NiO-Pt CE.
  • Utilized a PC/LiClO4 electrolyte containing a tetramethylthiourea/tetramethylformaminium disulfide (TMTU/TMFDS2+) redox couple.
  • Investigated the electrochemical performance and cycling stability of the fabricated device.
