An activated carbon monolith as an electrode material for supercapacitors

---

A B S T R A C T
Activated carbon binderless monoliths with high consistency and large porosity, synthesised
from a mesophase pitch, are studied as electrodes for supercapacitors. The electrochemical
cells prepared provided high capacitance values in sulphuric acid media (334 F g-1) and very low electrical resistivity, which results in a very efficient energy storage device (12 Wh Kg-1 maximum energy density and 12,000WKg-1 maximum power density). Long-term cycling experiments showed excellent stability with a reduction of the initial capacitance values of 19% after performing 23,000 galvanostatic cycles at -300 mA g-1.
