Electrochromic Characteristics of Nickel Oxide Film in Li~+ Containing Electrolyte

Electrochromic characteristics of nickel oxide film in Li+ containing electrolyte under nonstrict anhydrous conditions were studied,the amount Of injected Li+ ions was analysed quantitatively with Auger electron spectrum,the property of Li+ injection of the film was studied with galvanostatic method,the voltammogamm properties and the stability of the film in Li+ contaning electrolyte were also studied.Particularly,the influence of water impurities in the electrolyte on the voltommogamm and the electrochromic characteristics of the film was studied and the results show that when the water impurities are less than 5%, the injected charge and transmittance modulation range are nearly unaffected.
