The morphology, phase and chemical composition of the synthesized nanocoatings were characterized by XRD, SEM, EDX and Raman spectroscopy. The possibility of controlled changes in the morphology of the resulting compounds was demonstrated by changing the concentration of reagents and the number of processing cycles in order to obtain optimal electrochemical characteristics. Electrodes based on nickel foam and coated with films of porous manganese oxide showed high specific capacity (1324 and 297 F/g at a current density of 1 A/g in 1 M NaOH and 1 M Na2SO4, respectively), both in neutral and in aqueous alkaline electrolytes.</p></abstract><trans-abstract xml:lang="ru"><p>В настоящей работе пористое нанопокрытие из оксида марганца было получено путем ионного наслаивания из водных растворов перманганата калия и ДМСО. Морфология, фазовый и химический состав синтезированных нанопокрытий были охарактеризованы методами РФА, СЭМ, ЭДС и КР-спектроскопии. Возможность контролируемого изменения морфологии полученных соединений была продемонстрирована путем изменения концентрации реагентов и количества циклов обработки с целью получения оптимальных электрохимических характеристик. Электроды на основе вспененного никеля, покрытые пленками пористого оксида марганца, показали высокую удельную емкость (1324 Ф/г и 297 Ф/г при плотности тока 1 А/г в 1M NaOH и 1M Na2SO4, соответственно) как в нейтральном, так и в щелочном электролите.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оксид марганца</kwd><kwd>ионное наслаивание</kwd><kwd>нанопокрытия</kwd><kwd>электродные материалы</kwd><kwd>псевдоконденсатор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>manganese oxide</kwd><kwd>SILD</kwd><kwd>nanocoatings</kwd><kwd>electrode materials</kwd><kwd>pseudocapacitor</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This research was financial supported by grant of the President of the Russian Federation for state support of young Russian scientists (grant number MK-3864.2022.1.3).
