ELECTROCHROMIC DEVICE WITH LITHIUM POLYMER ELECTROLYTE AND METHOD OF MANUFACTURING THEREOF Russian patent published in 2014 - IPC C09K9/02 G02F1/15 

FIELD: chemistry.

SUBSTANCE: invention relates to applied electrochemistry, namely to an electrochromic device with a lithium polymer electrolyte and a method of manufacturing the electrochromic device. Claimed is the electrochromic device with the lithium polymer electrolyte, which includes an operating electrode in the form of a tungsten oxide film, a counterelectrode in the form of the Prussian Blue film and a polymer electrolyte with the following composition, wt %: lithium perchlorate 8-16, ethylenecarbonate 20-30, polymethylmethacrylate polymer 10-20, propylenecarbonate - the remaining part. The method of the electrochromic device manufacturing includes the preparation of the polymer electrolyte, preparation of working and auxiliary electrodes, in particular the cathode restoration of an auxiliary electrode before the assembly in the liquid lithium electrolyte, assembly and sealing. In the process of assembly a portion of the thickened polymer electrolyte is placed between the electrodes with their compression until complete contact of the counterelectrode with a separator of the operating electrode takes place, after which the excess of the electrolyte is removed. The device sealing is carried out by means of thermal glue.

EFFECT: application of the claimed method prevents the formation of gas bubbles in the electrolyte layer.
