M. Morita et al., Utilization of activated carbon fiber with mesopore structure for electricdouble layer capacitors, ELECTROCH, 69(6), 2001, pp. 462-466
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.
