PURPOSE:To enhance the discharge characteristic and the charge-and-discharge cycle characteristic of an organic electrolytic solution-secondary battery, by prescribing the percentage of the positive electrolytic solution content within the specified range, in an organic electrolytic solution-secondary battery whose negative active material is lithium. CONSTITUTION:In a positive electrode can 2, there is placed a positive electrode 1, which is prepared by adding a conductive agent and a binding agent to titanium sulfide as an active material in order to make a mixture, then compression-molding said mixture to form the positive electrode 1. A negative collector 5 is stuck to a negative electrode can 4, and a negative electrode 3 made of lithium rolled plate is pressed to attach to said can 4. Also, a separator 6 is impregnated with an organic electrolytic solution, and the positive electrode can 2 and the negative electrode can 4 are hermetically sealed by interposing insulated packing 7 between them in order to form an organic electrolytic solution-secondary battery. In this case, the positive electrode 1 is impregnated with the electrolytic solution. Said positive electrode 1 can adjust a molding pressure and change a packed density. The percentage of the electrolytic solution content in the positive electrode 1 based on the volume of the positive electrode 1 is selected as 0.2-0.4cc/cc. |
