Carbon material for electric double layer capacitor electrodes |
摘要 |
A carbon material for electric double layer capacitor electrodes which is obtained by a heat treatment and an activation treatment of a material pitch having a softening point in a range of 150 to 350°C, a ratio of amounts by atom of hydrogen to carbon (H/C) in a range of 0.50 to 0.90 and a content of optically anisotropic components of 50% or greater. The material pitch is preferably a synthetic pitch obtained by polymerizing a condensed polycyclic hydrocarbon such as naphthalene, methylnaphthalene, anthracene, phenanthrene, acenaphthene, acenaphthylene and pyrene in the presence of an ultra-strong acid catalyst such as a hydrogen fluoride-boron trifluoride complex. Electric double layer capacitors having a high electrode density and a high electrostatic capacity per unit volume can be constructed using the carbon material. |
