Abstract
The durability problem of Prussian blue in non-aqueous Li+-based electrolytes has been due to the deg-radation of the Prusian blue electrode matrix during the insertion/extraction processes by Li+. In this work, wedesigned and synthesised the Prussian blue without reducing the electrochromic performance in non-aqueous Li+-basedelectrolytes. Prussian blue was electrodeposited on a glass which has ITO coating, and the coating solution is a mix-ture solution of FeCl3 and K3Fe(CN)6 with deionized water added HCl, KCl, and LiCl, respectively. The durabilityof Prussian blue was evaluated by an in-situ transmittance measurement during a continuous and pulse potentialcycling test, and measured by electroactive layer thickness due to evaluating the degradation.
