Abstract. WO 3 electrochromic (EC) and ATO ion storage films were fabricated by a kinetic spray technique at various substrate heating temperatures. The optimal heating condition for WO 3 deposition was 80oC, which provided a total transmittance change of 31%.

Furthermore, the total transmittance change (at nm) of the WO 3 EC cell fabricated with the ATO ion storage layer Cited by: 4. Study and development of conducting polymer based electrochromic display devices.

Since the discovery of graphene, the quest for two-dimensional (2D) materials has intensified greatly. Recently, a new family of 2D transition metal carbides and carbonitrides (MXenes) was discovered that is both conducting and hydrophilic, an uncommon combination. To date MXenes have been produced as powders, flakes, and colloidal solutions.

Herein, we report on the fabrication of ∼1 × 1 Cited by: This review article presents a survey of the literature on pulsed laser deposited thin film materials used in devices for energy storage and conversion, i.e., lithium microbatteries, supercapacitors, and electrochromic displays.

Impedance spectroscopy (IS) appears destined to play an important role in fundamental and applied electrochemistry and materials science in the coming years.

In a number of respects it is the method of choice for characterizing the electrical behavior of systems in which the overall system behavior is determined by a number of strongly coupled.

Solid State Ionics has its roots essentially in Europe. First foundations were laid by Michael Faraday who discovered the solid electrolytes Ag 2 S and PbF 2 and coined terms such as cation and anion, electrode and the 19th and early 20th centuries, the main lines of development toward Solid State Ionics, pursued in Europe, concerned the linear laws of transport, structural Cited by: Electrochromic colouration efficiency is typically large in organic materials that are not very stable chemically.

Here we show that inorganic Bi()Ca()FeO() thin films exhibit a prominent electrochromic effect arising from an intrinsic mechanism due to the melting of oxygen-vacancy ordering and the associated redistribution of by:.
