PURPOSE:To provide a high-capacity nonaqueous carbonaceous secondary battery which has large current efficiency and is excellent in a cycle characteristic. CONSTITUTION:In a nonaqueous carbonaceous secondary battery comprising a positive electrode 1, a negative electrode 2 and an organic solvent electrolyte 11, the negative electrode is composed chiefly of flaky graphite whose carbon network face has a spacing d002 of less than 0.337nm, and the organic solvent electrolyte 11 contains gamma-butyrolactone. |
