Electric double layer capacitor and method for producing the same |
摘要 |
Disclosed is an electric double layer capacitor including polarizable electrodes immersed in an organic electrolyte, wherein a carbon material for forming the polarizable electrode is a carbon material including graphite-like microcrystalline carbon produced by effecting a heat treatment together with at least one of an alkali metal and an alkali metal compound at not less than a temperature at which alkali metal vapor is generated, and an electrostatic capacity is expressed by insertion of ions of a solute of the organic electrolyte into a space between microcrystalline carbon layers of the carbon material. Accordingly, it is possible to achieve an electrostatic capacity and a withstand voltage which exceed those of the conventional electric double layer capacitor based on the activated carbon system.
