Nano particles use in the electrochromic layer yields less input voltage and consume less power for large surface area. The WO3 is one of the extensively deliberated electrochromic materials. In this work, we prepared WO3 on the aluminum foil via electro chemical deposition. The structural features and the electrochromic behavior of the WO3 thin film are examined by SEM, XRD and cyclic voltammogram with the K+ intercalation using KI as the electrolyte. The cyclic voltammogram indicates large area of the intercalation /deintercalation with K+ ions overcome the difficulties of the intercalation with Li+ ions.
