文摘

Zeolite-templated carbon is a promising candidate as an electrode material for constructing an electric double layer capacitor with both high-power and high-energy densities, due to its three-dimensionally arrayed and mutually connected 1.2-nm nanopores. This carbon exhibits both very high gravimetric (140鈭?90 F g^鈭?) and volumetric (75鈭?3 F cm^鈭?) capacitances in an organic electrolyte solution. Moreover, such a high capacitance can be well retained even at a very high current up to 20 A g^鈭?. This extraordinary high performance is attributed to the unique pore structure.
