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 OCSiAl.ru, Novosibirsk).
