Abstract

An electrochromic switching device comprises a counter electrode, an active electrode and an electrolyte layer disposed between the counter electrode and the active electrode. The active electrode comprises at least one of an oxide, a nitride, an oxynitrides, a partial oxide, a partial nitride and a partial oxynitride of at least one of Sb, Bi, Si, Ge, Sn, Te, N, P, As, Ga, In, Al, C, Pb and I. Upon application of a current to the electrochromic switching device, a compound comprising at least one of the alkali and the alkaline earth metal ion and an element of the active electrode is formed as part of the active electrode.
