摘要
Five graphite samples have been applied as the positive electrode material in a novel graphite/activated carbon capacitor containing organic electrolytes. The effects of electrolyte composition (BF4-, PF6-) and weight ratio of activated carbon (negative electrode material) to graphite (positive electrode material) on the electrochemical behavior for this kind of capacitor have been investigated.
