PURPOSE:To stabilize the substantial packing density of activated powder carbon, by forming a carbon paste electrode ot the activated powder carbon of phenolic resin and a sulfuric acid in which poly-4-vinylpyridine of a specified value is dissolved. CONSTITUTION:An electric double layer capacitor is constructed of carbon paste electrodes 1, a porous separator 2, insulative gaskets 3, conductive separators 4 and a basic cell 5. Each electrode 1 is formed of the mixture of activated powder carbon of phenolic resin and a water solution of a sulfuric acid. The water solution of the sulfuric acid contains poly-4-vinylpyridine of 0.1-0.8wt.%. Thereby the substantial packing density of the activated powder carbon is stabilized. |
