MANUFACTURING METHOD OF ACTIVATED CARBON, AND ELECTRIC DOUBLE-LAYER CAPACITOR USING ACTIVATED CARBON OBTAINED BY THE MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of activated carbon, which has particle size suitable for an electric double layer capacitor, and is more reduced in quantity of surface functional groups.SOLUTION: The manufacturing method of the activated carbon includes: an activating step of activating a carbon raw material; a pulverizing step of adjusting the activated carbon to have 1-20 μm average particle diameter; and a heat treatment step of heating the pulverized activated carbon at 500-1,200°C under an inert gas atmosphere in this order.
