Abstract
There is provided an organic electrolytic cell equipped with a positive electrode, a negative electrode and a solution of a lithium salt in an aprotic organic solvent as an electrolytic solution, wherein PA0 (1) the positive electrode contains a metallic oxide, PA0 (2) the negative electrode is an infusible, insoluble substrate (PAS) having a polyacene type skeletal structure and a hydrogen/carbon atomic ratio of 0.5 to 0.05, the substrate being a heat-treated product of an aromatic condensation polymer, and PA0 (3) the total amount of lithium contained in the cell is 500 mAh/g or more, and the amount of lithium originating in the negative electrode is 100 mAh/g or more, based on the infusible, insoluble substrate (PAS) having a polyacene type skeletal structure as the negative electrode, PA0 the organic electrolytic cell being a secondary cell having a high capacity and high voltage.
