hybrid supercapacitor

A review of the current literature on hybrid supercapacitors (hybrid devices) in acid and alkaline electrolytes is presented.

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).
