摘要：

The determination of the maximum permissible degree of colouration for an electrochromic film in a particular device is technically important for long-term reversible modulation and safe operation. Chronopatentiometry combined with cyclic voltammetry have been used to examine the degree of colouration for WO3 films on various conducting substrates and electrolytes. The results revealed that an overreduced WO3 film with high amount of intercalated ions will lose its reversibility, lowering its electrochromic performance.
