Verbundwerkstoff aus Glaskohlenstoff-Aktivkohle, Verfahren zur Herstellung des genannten Verbundwerkstoffs, und den genannten Verbundwerkstoff verwendende-polarisierbare Elektrode zur Verwendung im elektrischen Doppelschichtkondensator

摘要

The present invention provides: a vitreous carbon-active carbon composite material wherein the vitreous carbon is derived from a polycarbodiimide resin; a process for producing the above vitreous carbon-active carbon composite material, which comprises firing a mixture of a polycarbodiimide resin and an active carbon, or a molded article of desired shape prepared from said mixture, in a non-oxidizing atmosphere; and a polarizable electrode for use in electric double layer capacitor, which consists of the above vitreous carbon-active carbon composite material. Said electrode is free from the drawbacks of prior art, has a low internal resistance, causes a low degree of powder detachment, has large electric capacitance per unit weight and per unit volume, and can be produced easily, quickly and inexpensively.
