Abstract
An electrolyte is disclosed, for example for use in a capacitor or in a battery. An electrolyte comprises a polysaccharide matrix; and carbon nanotubes embedded within the polysaccharide matrix. Further, apparatus comprising the electrolyte is disclosed. A method of manufacturing an electrolyte is disclosed. According to the method a polysaccharide solution is provided; carbon nanotubes are suspended within the polysaccharide solution; and the polysaccharide solution is dehydrated to obtain a gel.
Claims39
