摘要

The present invention relates to a method for producing an activated carbon electrode material doped with nitrogen, and to an electrode and an electric double layer capacitor using the same. In the method for manufacturing an activated carbon electrode material, a mixture of a nitrogen-containing polymer precursor and an activated carbon and a nitrogen- The present invention is directed to a method for manufacturing an activated carbon electrode material doped with nitrogen by mixing nitrogen at a ratio of 1: 1 to 4: 1 by weight and heat treating the activated carbon at a temperature of 700 to 900 ° C. In the electrode for a capacitor, the electrode is prepared by mixing a nitrogen-containing polymer precursor with an activated carbon and mixing the mixture of activated carbon and a nitrogen-containing polymer precursor in a weight ratio of 1: 1 to 4: 700 to 900 The electrode is made of an activated carbon material doped with nitrogen, which is formed using an electrode material formed by doping activated carbon with nitrogen gas. In the present invention, in the capacitor, the active carbon is mixed with the nitrogen-containing polymer precursor, and the mixing ratio of the activated carbon and the nitrogen-containing polymer precursor is mixed in the ratio of 1: 1 to 4: 4 by weight and the mixture is heat-treated at a temperature of 700 ° C to 900 ° C The present invention also provides an electric double layer capacitor using a nitrogen-doped activated carbon electrode including an electrode formed using an electrode material formed by doping activated carbon with nitrogen gas. Accordingly, by mixing the activated carbon with the nitrogen-containing polymer precursor, and by heat-treating the activated carbon and the nitrogen-containing polymer precursor, the characteristic of the activated carbon electrode material is improved by improving the wettability with the electrolyte and facilitating the ion input / And an improvement in output characteristics.
