An alternative system which could be an interesting candidate for electrochromic material is presented. The system is based on the deposition and stripping of a lead thin film on indium-tin oxide-coated glass (ITO). The electrodeposition and electrodissolution of lead was performed by cyclic voltammetry or potentiostatically by applying a potential step on the ITO electrode and simultaneously following the transmittance during the electrochemical study. The lead electrodeposition was studied in the presence and absence of CuCl2 and a higher Variation in the optical transmissivity in the presence of Cu+2 in the electrolytic solution was observed. A transmittance change of 60% for a deposition charge of 185 mC in the presence of CuCl2 was found.
