Activated carbons have long been used as supercapacitor electrode materials due to their exceptional properties, such as high surface area, good corrosion resistance and high electrical conductivity among others. A binder is generally required to bind the carbon particles into compact and manageable electrodes. It is well-known that the addition of the binder (e.g. PVDF, PTFE, etc.) has a negative influence in the properties of the active material due to the blockage of part of its porosity. This leads to an important reduction in surface area and an increase in electrical resistivity. Therefore, the use of a self-sintering material as electrode for supercapacitor would provide significant benefits. This paper reports the use of mesophase pitch (MP) and mesophase self-sintering carbon (MSC) for the synthesis of activated carbon monoliths (ACM) with high consistency and large porosity, without the need for a binder.
