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 and a higher variation in the optical transmissivity in the presence of in the electrolytic solution was observed. A transmittance change of 60% for a deposition charge of 185 mC in the presence of was found.
