Electric double layer capacitor.

摘要

An electric double layer capacitor has a pair of polarised electrodes (10) in the form of electrode bodies each comprising a porous sintered body, and a pair of current collectors (20) for collecting electric charges stored in the polarised electrodes, the current collectors being in the form of electrically conductive films. The electrically conductive films have surfaces dissolved by a solvent and joined to the electrode bodies with dissolved portions of the electrically conductive films being present in pores of the electrode bodies. The polarised electrodes and the current collectors are thus held in stable contact with each other, with a reduced contact resistance therebetween. The electric double layer capacitor thus has a low internal resistance.
