POROUS CARBON MATERIAL AND ELECTRIC DOUBLE LAYER CAPACITOR USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a porous carbon material exhibiting desired performance without applying a complicated step of treating a carbon material. SOLUTION: A dispersion of an aggregated carbon material 300 in which primary particles 100 have an average outer size of 10-95 nm or a carbon material having a DBP absorption value of≤250 cm3/100 g before activation is activated. The resultant porous carbon material is suitable for use in an electric double layer capacitor and a secondary battery. COPYRIGHT: (C)2008,JPO&INPIT
