Lives of organic secondary cells having organic electrodes wherein organic conductive materials such as polyacetylene are used as electroactive substance for the cathodes and/or anodes can be extended in the following way: Active species which are produced, when organic electrodes are doped with excess ions, and are responsible for the deterioration of cell functions are trapped with a substance having a frontier-electron density higher than those of the organic conductive materials, such as dimethylimidazolidinone, toluene, diphenylamine and dimethylaniline, by adding the substance to electrolyte, such as a solution of lithium perchlorate in propylene carbonate, of the cells. |
