Paper Abstract

Two batches of the samples of electrochromic cell with WO3 and IrOx electrodes and Sb2O5 (DOT) water based solid electrolyte were tested at constant contrast ratio up to 107 cycles or stored during five years and the changes of current-voltage characteristics were studied. Two kinds of the changes were observed. The shift of curves along the voltage axis is supposed to be associated with the changes in the oxidation degree of tungsten oxide, while the changes in their shapes are associated with changes of water content in pores. The processes in the samples during cycling and storing are discussed.
