二重層を利用した電気二重層コンデンサの改良に関し、
特に分極性電極が改良されたものに関する。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to the improvement of an electric double layer capacitor that utilizes an electric double layer formed at the interface between a polarizable electrode and an electrolyte.
In particular, it relates to an improved polarizable electrode.

量の改善が図られている。Equity 1it (No. 60-15138) discloses an electric double layer capacitor using carbon fiber as a polarizable electrode. That is, a felt-like, cloth-like, or paper-like carbon ram can be used as a polarizable electrode. This has led to improvements in the processability, utilization efficiency, and charge capacity per unit volume of polarizable electrodes.

かった。In addition, the specific surface area of activated carbon fibers is quite large at maximum 4000 II 12 / g, whereas the specific surface area of ordinary activated carbon is in the range of 1000 to 1500 m 2 /g, but the strength decreases as the specific surface area increases. Therefore, in the case of felt-like or cloth-like products, in reality it is 2000II.
It could only be used with a specific surface area of about 12/g. In other words, ≠→Activated carbon that achieves a high specific surface area! Although using lH, it was not possible to improve the capacitance much.

There is provided an electric double layer capacitor characterized in that it is constructed of a mixed molded body containing 1q of carbon powder and a caking material.
この発明では、炭素繊維を粉砕して冑られた炭素粉末を

可能とされている。Since this carbon powder is made into a mixed molded body together with a caking agent, it exhibits much higher strength than conventional carbon fibers made into felt or cloth shapes. Therefore, it is possible to use activated carbon 11M having a high specific surface area of up to 4000 m210, thereby making it possible to construct an electric double layer capacitor with a larger capacitance.

出発原料として用いることができる。Further, as the "caking material" used in this invention, any adhesive material can be used as long as it functions as a binder, but it is preferably one that is chemically stable with respect to the electrolyte system used. Furthermore, if the entire surface of the pulverized carbon powder is covered with the binder, the surface will be deactivated. Therefore, it is required that the entire surface of the carbon powder is not covered. Therefore, it is preferable to use a caking material in a dispersion state. As a caking agent in a dispersion state,
For example, latex, or in other words engineered resin, can be used as a starting material.

The particle size of the solid content of these latexes is 0.03 to 5 μm, and the shape is close to a sphere. The binder of the present invention is prepared by dispersing the latex in a dispersion medium such as water or an organic solvent to form a dispersion system.
