Abstract

In the present work we have studied in detail the lithiation behavior of reactively sputtered crystalline tungsten oxide (WO₃) films. These films, depending on their thickness and other deposition conditions, exhibit a wide range of changes under lithium insertion from deep coloration to no coloration at all. This gives the possibility of using the WO₃ films either as electrochromic (EC) layer or as counter electrode (CE) layer for lithium ion storage, respectively. From these results a quasi- symmetric electrochromic system encompassing a- WO₃ as EC layer and c-WO₃ as the CE layer is fabricated and studied for its electrochromic behavior.
