Изучение электрохимических свойств углеродных материалов для отрицательного электрода

Electrochemical characteristics of electrodes based on various carbon materials such as expanded graphite, nanotubes, black carbon for hybrid supercapacitors C/PbO2 with acid electrolyte were investigated. It was shown that the highest values of the capacitive characteristics were obtained using TUBALL graphene nanotubes (LLC, Novosibirsk).

Solid proton-conducting ceramic electrolyte for energy storage units

The paper considers the electrochemical properties of potassium polytitanate synthesized at the values of pH varying from 3 to 8 in a wide temperature range from ? 26 to + 80°C. The conductivity values and the activation energy were determined with the help of the method of impedance spectroscopy. The application of the obtained material used as a ceramic solid electrolyte in the energy storage units operating at low temperatures in the Far North is considered in the article.
