Title: Electrochromic display element
Inventor: FUKUZAWA TAKAHISA
IPC: G02F1/15
Filed: 1993-10-04
Abstract: PURPOSE:To improve the service life for repeatedly driving the electrochromic display element by using a tetrafluoroborate aq. solution as the driving electrolyte. CONSTITUTION:As for the driving supporting electrolyte, sodium ion (Na<+>) is fixedly prepared as a cation, the concn. of the electrolyte is fixed to 0.1mol/l and various kinds of ions are prepared for an anion. The electrolyte is exemplified as sodium chloride (NaCl), sodium perchlorate (NaClO4) and sodium tetrafluoroborate (NaBF4) solutions, etc. Then the cyclic-voltammetric data are continuously measured with respect to an electrode on which a Fe(BPDP)3 film is formed. The change in peak current value of the voltammogram thus obtained is traced to evaluate the repeatedly driving stability of the electrolyte. This cyclic-voltammetric measurement is performed by using the three-electrode method under the conditions of 20mV/sec scanning speed and 0V  +1.5V vs scanning potential width. Among the eletrolytes which show considerable decreases in the current value of their cyclic-voltammograms, only the NaBF4 solution shows a low rate of decrease in the current value and therefore the service life in terms of frequency of the repeated driving is improved by using the NaBF4 solution as the electrolyte.
