Electric double layer capacitor.

摘要

An electric double layer capacitor which utilizes the principle of an electric double layer in the interface between polarised electrodes (2) and an electrolyte, each of the polarized electrodes being composed of minute active carbon particles of coal tar which have a specific surface area ranging from 1,000 to 4,000 m<2>/gram. Many such minute active carbon particles are packed in a unit volume for an increased electrostatic capacitance.
