A study of the effect of cycling modes on the electrochromic properties of Ni(OH)2 films

Optimization of the deposition conditions for Ni(OH)2 films for electrochromic elements of “smart” windows

“…The next problem to solve is which additives can be used to improve film adhesion to the substrate that can also be served over a wide range of temperatures. The latter is partially solved by the authors in [7,12,13,16]. Wide temperature range is required because the absorbed light would be transformed into heat, which can result in the film temperature rising up to 80 °С and more.…”

“…The following solutions were used for deposition: 1, 0.1 and 0.01 М Ni(NO 3 ) 2 . It should be noted that unlike in previous works, the electrolyte did not contain any additives [6,7,[11][12][13]16]. This is necessary to isolate the influence of additives from the main processes.…”

“…High reversibility of the electrochemical reaction (1) is the reason why this material is widely used in electrochemical accumulators [8,9] and supercapacitors [10,11]. This is also the reason why Ni(OH) 2 films are viewed as promising electrochromic material [12,13].…”

“…Further addition of the precipitant (after precipitation of less soluble compound) would result in precipitation of second compounds (more soluble, higher SP). Electrodeposition should be conducted at a very low current density (0.1 mA/cm 2 [22][23][24][25]). The electrodeposition occurs in two stages -electrochemical generation of ОНions at the cathode (1), followed by the chemical formation of Ni(OH) 2 (2).…”

Material selection for the mesh electrode of electrochromic device based on Ni(OH)2

“…The core of these "smart windows" are electrochromic films, in which electrochemical reactions occur. During these reactions, transparent forms become colored [1].…”
