## Abstract

A chemical power supply comprises a cathode and an anode including active materials dissolved in an electrolyte based on an organic solvent, and a diaphragm for separating the cathode from the anode. The cathode active material is a stable radical selected from the group consisting of a stable cation-radical of an aromatic amine, a stable cation-radical of a heterocyclic compound, a stable electrically neutral radical of an aromatic oxygen-containing compound, a stable electrically neutral radical of an aromatic nitrogen-containing compound, while the anode active material is a stable anion-radical of an aromatic compound.
