The interface between the electrochromic (EC) electrode and ionic conductor is crucial for high-performance extraordinarily stable EC devices (ECDs). Herein, effect of ALD–AZO interfacial layer on performance WO3 thin film was examined, revealing that an introduction to Al3+-based complementary ECDs can lead improved stability, such as extraordinary cyclability more than 20,000 cycles, outstanding coloration efficiency 109.69 cm2 C–1, a maximum transmittance modulation 63.44%@633 nm. probable explanation introduced effectively regulate band gap WO3, promote electron transport process, induce formation robust solid electrolyte interphase protect during cycling. These findings offer valuable insights enhancing films new space construction advanced multivalent ECDs.
