Activated carbons and other types of porous carbons have been attracted many attentions in several industrial fields currently. However, experimental results for characterization of the structure of porous carbons show no distinct features, and accordingly the structural information obtained from the experimental results has been limited to qualitative one. This paper contains a quantitative characterization of porous carbons, especially for electric double layer capacitor applications. Investigations were carried out by applying new analysis methods to data by XRD measurement for microporous carbons, TEM observation of mesoporous carbons, and multilateral characterization of total pore and solid structures. It was also represented about a development of carbon-based electrodes for electric double-layer capacitors by using carbon aerogels known as one of the candidates for the application in this field. Some recent topics are addressed about a preparation of metal-loaded carbon aerogels by a pre-mixing method and an ion-exchange method, as well as their electric double-layer capacitor behavior estimated by cyclic voltammograms in 1M-H2SO4.
