An electrochemical cell comprises a cathode and an anode including active materials dissolved in an electrolyte based on an organic solvent, and a diaphragm separating the cathode from the anode. The cathode active material is a stable cation-radical of an aromatic amine, or a stable cation-radical of a heterocyclic compound, or a stable radical of an aromatic oxygen- containing compound, or a stable radical of an aromatic nitrogen- containing compound, while the anode active material is a stable anion-radical of an aromatic compound. |
