Abstract

Electrochromic batteries (ECBs) represent a novel integration of energy storage and optical modulation technologies, offering versatile applications from smart windows to portable electronics. This work explores the potential of zinc-ion (Zn²⁺) electrochromic batteries utilizing tungsten trioxide (WO₃) as an active material. To address research gaps, the study focuses on coating techniques and hybrid ion electrolytes to enhance performance and sustainability. Spray coating with ethanol solvent demonstrates superior uniformity and film quality compared to de-ionized water, attributed to Marangoni flow effects. Moreover, hybrid Zn-K electrolytes show enhanced electrochromic and electrochemical performance, offering higher ΔT (50%) modulation and cyclic stability (10000 s). Theoretical analysis confirms the favorable interaction of K⁺ ions with WO₃. Prototype ECB devices exhibit exceptional cyclic stability (3000 cycles), rapid self-charging capabilities (10 min), and reversible optical modulation (40%), showcasing the potential for sustainable energy storage solutions in smart electronics.

通过与马兰戈尼流集成的可扩展喷涂涂层实现可自充电的水性 Zn2+/K+ 电致变色储能装置

电致变色电池（ECB）是能量存储和光学调制技术的新型集成，可提供从智能窗户到便携式电子产品的多种应用。这项研究探索了利用三氧化钨（WO3）作为活性材料的锌离子（Zn2+）电致变色电池的潜力。为填补研究空白，该研究侧重于涂层技术和混合离子电解质，以提高性能和可持续性。与去离子水相比，使用乙醇溶剂进行的喷雾镀膜具有更好的均匀性和薄膜质量，这归功于马兰戈尼流效应。此外，混合 Zn-K 电解质显示出更强的电致变色和电化学性能，提供更高的ΔT（50%）调制和循环稳定性（10000 秒）。理论分析证实了 K+ 离子与 WO3 的良好相互作用。原型 ECB 器件具有优异的循环稳定性（3000 次）、快速自充电能力（10 分钟）和可逆光学调制（40%），展示了智能电子产品中可持续能量存储解决方案的潜力。
