| Abstract: | Hybrid supercapacitors were fabricated using Ni (OH)_2 positive negative and electrodes of activat- ed carbon.The effects of the pore size distribution,BET specific surface and wet characteristic on the ca- pacitance and high power charge discharge performance of the supercapacitors were discussed by means of nitrogen gas adsorption,wetting angle measurement and constant current charge discharge techniques.Re- sults show that activated carbon with high wet characteristic and high existence of mesopore structure can give large capacitance and good high power charge and discharge performance. |
