Abstract
Most commonly used electrochromic device was consisted to three parts; electrochromic layer, ion conduction layer and electrolyte. In electrolyte, liquid type was typically used, but in had problems of difficult sealing and danger for practical application [1]. Therefore, many attempts for replacing liquid electrolyte to other type electrolyte, solid electrolyte such as LiPON and polyelectrolyte, and ionic liquid were tried in electrochmical device. In this research, we used ionic liquid as a new electrolyte. The low viscosity and low volatile properties in ionic liquid dan attribute to advantages of solid and liquid electrolyte together. Firstly, we prepared nichel oxide film and tungsten oxide film by sol-gel method referred to previous researches [2]. And then, the two electrodes were adhered using a sealant, surlyn(Dupont, 30㎛), and the ionic liquid, [AM]Im-BF4 dissolved LiBF4, was injected into the space between the two electrodes. The electrochromic performance of device was measured by continuous potential test. As a result, electrochromic devise with ionic liquid was shown stable electrochromic performance and good durability during long cycling.
