TL;DR: In this article, a model is proposed in which the electrocoloration process is attributed to the formation of a ‘tungsten-blue’ phase following cathodic reduction by active hydrogen.
Abstract: Studies of electrochromism in evaporated and chemically prepared tungsten-oxide films have shown that electrocoloration takes place only in films containing H2O. A model is proposed in which the electrocoloration process is attributed to the formation of a ‘tungsten-blue’ phase following cathodic reduction by active hydrogen.

TL;DR: In this paper, a flexible, electrochromic and rechargeable battery was realized by successfully matching polypyrrole (PPy, as cathode) with zinc (Zn, as anode).
Abstract: A rechargeable battery with both flexibility and electrochromism integrated into a single apparatus is a major component for smart flexible electronics. However, suitable electrode materials with electrochromic properties are still being searched for. Here, for the first time to the best of our knowledge, we realize a flexible, electrochromic and rechargeable battery by successfully matching electrochromic polypyrrole (PPy, as cathode) with zinc (Zn, as anode). The fabricated rechargeable Zn//PPy battery delivers a high capacity of 123 mA h gPPy−1. It possesses flexibility and an electrochromic capability of turning from black to yellow when the voltage changes from 1.2 to 0 V. Therefore, the battery exhibits a unique function of a short circuit chromatic warning which turns yellow at 0 V. Our battery, uniquely combined with these multiple smart features, represents solid progress in smart flexible electronics.

TL;DR: In this article, a review of NIR electrochromic dyes for electro-optic switching at the wavelengths used for silica-based optical telecommunications networks is presented. And a detailed survey of recent work in the field can be found in Section 2.
Abstract: Redox-active transition-metal complexes which show strong changes in their electronic spectra in the near-infrared (NIR) region in different oxidation states are attracting increasing interest as NIR electrochromic dyes for electro-optic switching at the wavelengths used for silica-based optical telecommunications networks. This brief review surveys recent work in the field based on ruthenium(II)-dioxolene, tris(pyrazolyl)borato-molybdenum(V) and mixed-valence Ru(II)-Ru(III) complexes, which all show strong NIR electrochromism and have been incorporated into prototypical devices such as the variable optical attenuator by attachment to transparent electrodes, either by adsorption or polymerisation.
