Abstract
The present invention provides a secondary battery and a capacitor which may provide an excellent high rate and cycle characteristic as well as sufficient electromotive force and capacity. The secondary battery and a capacitor have an active material of an electrode comprising a trimer compound comprising three units of indole or indole derivatives in condensed ring form, wherein the second position and the third position of each unit form a six-membered ring, and a proton which can be utilized as a charge carrier of the trimer compound.
