PURPOSE: To obtain an electrochemical energy storing unit having a high energy density and a long cycle time by employing a pyrrole based conductive polymer and a composition containing a specified ionic group. CONSTITUTION: The electrochemical energy storing unit employs a conductive polymer selected from polypyrrole and/or substituted polypyrrole, and a composition containing an ionic group including at least one R-sulfate group or R sulfonate group (R is alkyl group or aryl group). Normally, it contains 0.01-0.9 parts of ionic group per 1 part of pyrrole and/or substituted pyrrole and it is doped with cations or anions. Doping is performed preferably in a solution of propylene carbonate, e.g. LiClO4 . The composition can be employed in the electrode of a capacitor, a battery, a cell, etc., and an anode comprises a film of the composition or an electrode coated therewith. A super capacitor employing the composition has an electrode capacity of at least 120 F/1g of electrode and a rechargeable generator has an element exhibiting mass capacity of at least 4mA.h stored during discharge. |
