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.
