摘要：

An electrochromic thin film of amorphous WO3nH2O was fabricated by spin-coating a peroxo-polytungstate solution. Coloration and bleaching kinetics of the film in contact with a solid polymer electrolyte were investigated by a chrono-amperometric method using a cell, Li/polymer/WO3nH2O, ITO. The transition currents were analyzed on the basis of a newly proposed theory for the diffusion-controlled current generated by a voltage step in such a cell without a reference electrode. It was found that both kinetics were controlled by the diffusion process and the chemical diffusion coefficients of lithium were, in common, about 5 x 10(-12) cm2 s-1.
