PURPOSE:To provide an organic electrolytic secondary battery excellent in its cyclic characteristic at low cost, further facilitating measurement of remaining capacity. CONSTITUTION:An organic electrolyte secondary battery is composed of negative electrode material being graphite, a positive electrode active material formed mainly of a manganese oxide expressed by a structural formula Li1-xMn2O4 (where, 1>x>=0), organic electrolytic being mixed solvent made of high boiling point solvent and low boiling point solvent, with its volumetric mixing ratio including 30% or more and 70% or less of low boiling point solvent. |
