CARBON MATERIAL FOR ELECTRIC DOUBLE LAYER CAPACITOR ELECTRODE AND METHOD FOR PRODUCING SAME |
摘要 |
The present invention provides a method for producing a carbon material for an electric double layer capacitor, having a low internal resistance and a high capacitance per unit volume. The method comprises activating a graphitizable carbon material used as the raw material with 3 or more alkali metal compounds to produce an activated carbon having a BET specific surface area of 1500 to 3000 m 2 /g and a pore diameter corresponding to the maximum value in the pore size distribution as determined by the MP method within the range of 1 to 2 nm. |
