SUPERCAPACITOR AND NITROGEN-DOPED POROUS CARBON MATERIAL

摘要

The invention pertains to the use of a nitrogen-doped porous carbon material in a supercapacitor, wherein the nitrogen-doped porous carbon material has the following properties:- a nitrogen content in the range of 0.50 to 8.0 at% as determined via XPS- a specific surface area (N2 , BET) of at least 1000 m2/g- a total pore volume as determined by N2 adsorption of at least 0.80 ml/g,- a N2 adsorption pore size distribution which is such that at least 50% of the pore volume is in pores with a diameter of above 2 nm.;The invention further pertains to a supercapacitor, an electrode for use in a supercapacitor, to specific nitrogen-doped porous carbon materials and to methods for the manufacture thereof.
