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.
