Abstract

The invention provides an active carbon which is needed by an electric double layer capacitor (EDLC) that has large electrostatic capacity and low-price raw material, or most suitable for other similar usage. The invention has the technical proposal that bagasse produced in Okinawa or other regions as raw material, more particularly, the technique is that the husk part obtained by separating the core and the exocuticle part of the bagasse is carbonized to prepare carbonide, and the principle technique is that the carbonide is processed by basic activation to prepare the active carbon.

Description

technical field [0001] The present invention relates to a related production method of activated carbon with a large specific surface area. This activated carbon is the main component of polarized electrodes of electric double layer capacitors (Electric Double Layer Capacitor; EDLC), and can also be optimally used for other similar purposes. In addition, the present invention also relates to a related manufacturing method of an electric double-layer capacitor, which has a pair of polarized electrodes, a separator film disposed between the polarized electrodes, and a pair of connected polarized electrodes. A collector electrode, and an electrolyte in contact with the aforementioned pair of polarized electrodes. Background technique [0002] Conventionally, electric double-layer capacitors in which activated carbon is used as a main component of polarized electrodes are known. Such an electric double-layer capacitor is disclosed, for example, in Japanese Patent Laid-Open No....
