The periphery is sealed with a sealing material 3. A conductive sheet 4 serving as a collecting electrode is disposed outside the electrode 1.

する。The electrodes are required to have a large surface area in order to increase the capacitance, a low electric resistance, a good corrosion resistance and a high withstand voltage. The above-mentioned paste-like electrode has an advantage that the activated carbon powder is utilized as it is, so that the surface area is large, but the electric resistance is large and the assembling work of the capacitor is troublesome. Since the molded body has a low electric resistance because the carbon forms a skeleton and is continuously connected, it is difficult to increase the surface area by activating the molded body. Activated carbon fiber is expensive, and its use not only increases the cost, but also does not provide sufficient electric resistance and surface area. SUMMARY OF THE INVENTION An object of the present invention is to provide a method for producing an electrode which has a large surface area and therefore a large capacitance, is excellent in electric resistance, corrosion resistance and strength, and is easy in production and handling.

This is a method for producing a polarizable electrode material.

機溶剤を加え粘度を調整することもできる。As the activated carbon, ordinary activated carbon such as carbonized and activated charcoal, sawdust, coal, phenol resin and the like is used. This activated carbon is used after being ground to about 50 μm or less. As the cellulosic fibers, pulp that is usually used for paper is suitable, but other fibers such as rayon, cotton, and the like, in which cellulose fibers are shortened can be used. The fibers are then used in sheets, where the papermaking process is easier to manufacture,
In this case, the length of the fiber is preferably 5 mm or less. The phenol resin is preferably a resol type, and the most advantageous production method is to impregnate the fiber sheet in an uncured liquid state. At this time, in order to facilitate the impregnation, an organic solvent such as acetone can be added to the phenol resin to adjust the viscosity.

もできる。The activated carbon powder as a component of the sheet in the present invention is preferably at least 30% by weight (hereinafter,% means weight%) in order to increase the surface area. The upper limit is preferably 50% or less due to restrictions by other components. Cellulosic fiber facilitates papermaking and maintains the strength of sheets and electrodes.
It is preferably 0% or more, and is preferably up to about 70% due to restrictions of other components. The phenol resin is preferably at least 10% in order to maintain the strength of the sheet and the electrode, and is preferably at most 30% because too much phenol resin blocks pores of the activated carbon powder. The amount of the resin in this case is a solid content excluding the solvent, water and the like.
The sheet is mainly composed of the above-mentioned components, and fibers such as polyacrylonitrile and polyvinyl alcohol and graphite fine powder or the like in order to improve conductivity can be added in a total amount of about 20% or less.

ことによっても調整することができる。[0007] A preferred method of making the sheet is to make the paper in the same way as making paper with pulp or the like, and impregnate it with a phenolic resin which is in an uncured and liquid state. The activated carbon powder is preferably contained in the papermaking together with the pulp or the like. In particular, in the case of fine powder, it can be mixed with the phenol resin and contained in the sheet simultaneously with the impregnation of the resin. Further, commercially available paper such as filter paper may be used, and the sheet in the present invention includes such paper. Resin impregnation involves immersing the sheet in a solution of the resin, then pulling it up,
The impregnation amount is adjusted by passing between rolls as necessary. The amount of impregnation can also be adjusted by changing the concentration of the resin solid content with a solvent.

It is dried at about 20 to 180 ° C. to obtain a prepreg sheet. When the prepreg sheet is thick, it can be cured and fired as it is to produce a product. However, it is desirable to laminate a plurality of thin sheets, press-bond, cure and fire. If the sheet is thick, it is difficult to make paper, and it is difficult to uniformly impregnate resin or activated carbon powder. Prepreg sheet is 150-2
Heat to about 00 ° C to cure. At this time, it is preferable that the material is compressed to about 0.5 to 10 kg / cm 2 by sandwiching it with a graphite plate or the like. The compression prevents the generation of large pores, and in the case of lamination, the adhesion between the sheets is improved, and the surface area is increased by increasing the bulk density of the electrode material.

ましい。[0009] The cured sheet is then fired under an inert atmosphere. The firing is preferably performed, for example, by sandwiching the sheets between graphite plates so as not to warp. At this time, the porosity can be adjusted by applying pressure. If the temperature rise of the firing is too early, the decomposition and volatilization of the resin and the fiber become rapid, and large pores are generated. Therefore, it is preferable to apply the temperature up to about 800 ° C. for 20 to 100 hours. The final temperature of the calcination is not particularly limited, and can be a temperature close to 3000 ° C. as in the case of normal graphitization of carbon. In particular, when firing at a high temperature, impurities are volatilized and removed, which is preferable as an electrode.

ている。In the electrode of the present invention, the activated carbon powder is mixed with the phenol resin. However, since the amount of the resin is not so large, the pores of the activated carbon powder are hardly clogged and the surface area is large. Cellulosic fibers are partially degraded during the carbonization process, but a significant portion remains in the form of carbonized fibers. Fine pores are generated due to partial decomposition and volatilization of the fiber, which leads to an increase in surface area. The carbonized fibers also help improve strength. Since the sheet before carbonization is also reinforced with fibers, it has high strength and is easy to handle. In addition, the use of phenolic resin reduces the clogging of the pores of activated carbon compared to other resins such as furan resin (resin can be cured in a short time and the amount of permeation into the pores can be suppressed), and mass production It is excellent in terms of properties and cost.

The slurry aqueous solution mixed with 50% was paper-made by a round mesh paper machine (Toyo Seiki Seisaku-sho, TSS type sheet machine) to obtain a mixed sheet. The sheet was 0.25 mm thick and weighed 110 g / m 2 . The sheet was immersed in a phenolic resin (BRL-120Z, manufactured by Showa Polymer Co., Ltd.) and dried at 150 ° C. for 1 minute to obtain a prepreg sheet. The resin impregnation amount (solid content) was 24%. Six of these are laminated, sandwiched between graphite plates, and pressurized at 5 kg / cm 2 to
C. for 10 minutes. The resulting sheets were joined together. Four of them were stacked and sandwiched between graphite plates, and the temperature was raised to 1000 ° C. for 4 days in a non-oxidizing atmosphere. After natural cooling, the four carbon plates removed from the graphite plate were not bonded,
Independent and each had a good appearance. Two of the four carbons were heated to 2800 ° C. at a rate of 10 ° C./min for the purpose of removing impurities and improving physical properties by using an Acheson-type graphitization furnace.
