PURPOSE: To provide a safe secondary battery with high capacity, high voltage and low internal resistance which is easy to manufacture by using a metal oxide as a positive electrode and a specified insoluble and infusible base as a negative electrode, controlling lithium quantity, and property carrying the lithium. CONSTITUTION: This organic electrolytic battery has a positive electrode and a negative electrode and uses an aprotic organic solvent solution of lithium salt as an electrolyte. The positive electrode of the battery is formed of a metal oxide such as Lix CoO2 . The negative electrode is formed of an insoluble and infusible base (PAS) with polyacene frame structure consisting of the thermally treated material of an aromatic polymer and having a H.C ratio of 0.5-0.05. To the negative electrode PAS, the total lithium quantity contained in the battery is set to 500mAh/g or more, the lithium derived from the negative electrode is set to 100mAh/g or over. The lithium derived from the negative electrode is carried by the direct contact between the lithium arranged on the whole area or a part of the outer circumferential part of a negative electrode plate within the same plane and at least a part of the negative electrode PAS or negative electrode current collector. |
