| 摘要: |
A series of carbon spheres with various porous texture parameters were prepared from polystyrenebased macroreticular resin spheres by carbonization and activation. The as-prepared carbon spheres had a maximum specific surface area of 996 m2 g？1, total pore volume of 1.34 cm3 g？1 and average pore size of 5.39 nm. Moreover, these carbon spheres showed a mesopore size distributed mainly in about 40 nm. A high specific capacitance of 153 F g？1 for carbon sphere by carbonization, 164 F g？1 for carbon sphere by activation for 1 h and 182 F g？1 for carbon sphere by activation for 2 h can be obtained. Moreover, a specific energy between 2.3 and 5.1 Wh kg？1 for these carbon spheres can be obtained in 6 mol L？1 KOH electrolyte. |
