Paper Abstract

The results concerning the optical, electrochemical, and mechanical properties of the reversible electrochemical intercalation of cations H+ and Li+ on nonstoichiometric, anhydrous dc sputtered NiOx films deposited onto thin (0.15 mm) ITO- covered glass plates are presented. It is shown that these properties greatly depend on the optical state of the samples prior to any electrochemical intercalation procedure and that the intercalation of cations induces a compressive mechanical stress, which is reversible both for lithium and for hydrogen cations, and is greater in the first case. Electrochromic efficiencies also are discussed for both cases.
