PURPOSE:To prevent an increase of the inner resistance after the cell is assembled and realize a satisfactory electric capacity, by using a positive electrode composite of manganese dioxide as the active substance with the thickness 0.5 mm, and making the mixing ratio of the binder in the positive electrode composite 6 to 10 wt% of the all composite. CONSTITUTION:The thickness of a positive electrode composite 4 accommodated in a case 1 of a flat organic electrolyte cell with the thickness 0.2 mm, for example, is made 0.5 mm. The mixing ratio of a polymer of ethylene tetrafluoride and propylene hexafluoride used as a binder of the positive electrode composite is made 6 to 10 wt% of the all composite. The mixing ratio when styrenebutadien rubber is used as a binder is also made 6 to 10 wt% of the all composite. An increase of the inner resistance after the cell is assembled is prevented in such a way, and a satisfactory electric capacity can be realized. |
