摘要： Activated carbon useful as polarizable electrode material for an electric double-layer capacitor can be obtained by mixing a carbonaceous material and an alkali metal hydroxide while maintaining a solid state, granulating the obtained mixture while maintaining its solid state, dehydrating the obtained granulated substance while maintaining its solid state, and subjecting the granulated dehydration product obtained in the dehydration step to an activation treatment. The preferred pressure of the granulation treatment in the granulation step is 0.01 to 300 Torr, and the preferred temperature of the granulation treatment is 90 to 140° C. The preferred pressure of the dehydration treatment in the dehydration step is 0.01 to 10 Torr, and the preferred temperature of the dehydration treatment is 200 to 400° C.

摘要： In activated carbon obtained by subjecting a carbonaceous material to an activation treatment, the overall content of alkali metals is set at 100 ppm or less, or the overall content of heavy metals is set at 20 ppm or less and the overall content of alkali metals is set at 200 ppm or less. In cases where such activated carbon is used as a raw material in electronic devices, the formation of dendrites by the reductive deposition of alkali metals or heavy metals tends not to occur, so that problems such as short-circuiting or the like tend not to arise, and a good rate of self-discharge retention is shown.

摘要： A polarizable electrode to be used in an electric double layer capacitor, which has an excellent depressing effect on the generation of gas, is coated on the surface thereof with a thin film layer of a gelling organic polymer compound whose thickness is less than 5 μm. As the gelling organic polymer compound, organic polymer compounds having —COO— bonds, or preferably acrylic polymers, can be used. Specific examples thereof include polyalkyl methacrylate or polyalkyl acrylate, which are capable of forming a stereocomplex. Among these, poly(methyl methacrylate) is preferable. Polyvinylidene fluoride resins can also be preferably used. It is preferable that an electrical double layer capacitor include a pair of polarizable electrodes and a separator disposed therebetween and that at least one of the pair of polarizable electrodes be the above-described polarizable electrode having an excellent depressing effect on the gas generation.
