Abstract
Rate capability of activated carbon fiber with controlled pore structure ha s been investigated as the electrode of electric double layer capacitors us ing organic electrolyte solutions. The pore structure of carbon fiber much influenced the rate capability, depending on the composition of the organic electrolytes. The carbon fiber with developed mesopore structure that has been prepared from pitch containing acetylacetonatoyttrium, Y(acac)(3), sho wed high rate capability, whereas the conventional carbon fiber with smalle r average pore size gave poor rate capability. Effects of the cation size o f the electrolyte on the rate capability was relatively small for the activ ated carbon fiber with mesopore structure.
