Abstract
An electrode for a secondary or rechargeable battery using a conducting polymer as an active material is provided, which realizes a large capacity, a good cycling property, and a high power density. This electrode is comprised of an active material layer having an active material made of a mixture of a nitrogen-containing compound polymer and a quinone-system compound. The molar ratio of the nitrogen-containing compound polymer and the quinone-system compound is preferably in the range of 0.25:0.75˜0.75:0.25 and is more preferably in the range of 0.33:0.66˜0.66:0.33. The active material of the electrode is produced by using a mixture of powders of the nitrogen-containing compound polymer and the quinone-system compound.
