Abstract

Модификацию поверхности угольных электродов наночастицами диоксида марганца проводили методом анодного электрохимического осаждения. Структурные характеристики и элементный состав MnO2/С-электродов изучены методами энергодисперсионного микроанализа, просвечивающей электронной микроскопии. Электрохимические характеристики электродов исследованы методами циклической вольтамперометрии, гальваностатического заряда-разряда и импедансной спектроскопии. Проведено сравнение удельной емкости электродов MnO2/С в 0.5 М растворах Li2SO4, Na2SO4 и K2SO4. Установлено, что большие значения удельной емкости полученных материалов реализуются в растворе сульфата натрия.
