The main ones are chemical current sources, vari able transparency “smart” windows, devices for carrying out electrocat alytic reactions, sensors for deter mining various substances. In this regard, methods of nickel hydroxide synthesis are of great interest, espe cially those that allow forming nick el hydroxide directly on the surface of electrodes. One of these methods is electrochemical deposition with cathodic current polarizationelectrochromism, electrodeposition, nickel hydroxide, polyvinyl alcohol, nickel nitrate, current efficiencyEfficiency definition of the deposition process of electrochromic Ni(OH)2-PVA films formed on a metal substrate from concentrated solutionsArticle10.15587/1729-4061.2021.246511
