ABSTRACT:
A composite suitable as a charge-storing material for electrochemical capacitors contains carbon nanotubes and a carbonaceous materiel. The carbonaceous material is the carbonization residue of a biopolymer or seaweed rich in heteroatoms. Wherein the carbonization residue of the biopolymer or seaweed is electrically conductive and has a heteroatom content as detected by XPS of at least 6%.
