【Abstract】 The effects of different activated carbon fibers and their surface area as well as the electrolytes on the specific capacitance of electric double layer capacitors made from activated carbon fibers were investigated. The influence of carbon’s surface area and the electrolytes on the stability of circular charge of electric double layer capacitors was also addressed. The results show that the activated carbon fibers are better electrode materials for double layer capacitor than the activated carbon powder. It is also found that in the case of activated carbon fibers, higher surface area is not always necessary in terms of the specific capacitance when the same base is used.更多还原
