Abstract
There are disclosed activated carbon for use in an electric double-layer capacitor electrode, the carbon being capable of improving rate characteristics and float characteristics of the electric double-layer capacitor electrode, and a method for manufacturing the activated carbon. The method for manufacturing the activated carbon for use in the electric double-layer capacitor electrode, comprising the steps of: grinding a carbon raw material to adjust an average particle diameter of the carbon raw material into a range of 1 μm to 15 μm; mixing the carbon raw material whose average particle diameter has been adjusted, with an alkali activator to obtain a mixture; and an activation treatment comprising heating the mixture under an atmosphere of an inert gas and then under an atmosphere of a mixed gas of the inert gas and water vapor.
