Abstract
An electrode material for an electric double layer capacitor which include spherical particles (A) having an electrode active material and a thermoplastic binder, wherein the spherical particles (A) have a sphereness degree of not larger than 20% as defined by the equation: sphereness degree (%) (L−L)×100/L, where Lis short axis diameter, Lis long axis diameter, and L=(L+L)/2. The particles (A) are made preferably by a process of mixing together the electrode active material with the thermoplastic binder in a solvent to form a liquid dispersion; and then, spray-drying the liquid dispersion. An electric double layer capacitor having the electrode made from the electrode material is characterized as having low internal resistance and high capacitance.
