PURPOSE:To obtain the improvement in discharge characteristics with no scattering of internal resistance of a nonaqueous electrolytic solution cell by making the effective area of roughened surface of a mouth sealing plate inside larger than 75% of pressure fixed area of a negative electrode active material, when the negative electrode active material is fixed by pressure to the inside surface of mouth sealing plate. CONSTITUTION:When the seatlike negative electrode active material 2 is fixed by pressure to a mouth sealing plate 1, they are fixed by pressure after setting the effective area of roughened surface of the mouth sealing plate 1 inside larger than 75% of pressure fixed area of the negative electrode active material 2. And then, a nonaqueous electrolytic solution cell is formed by combining the positive electrode composite material 8 filling a positive electrode case 4, a separator 6 and a gasket 3, etc. Therefore, the wide pressure fixed area of negative electrode active material 2 to mouth sealing plate 1 is obtained, and, since it is possible to perform reliable pressure fixing, the improvement in discharge characteristics can be obtained by preventing the scattering of its internal resistance, and further, by restricting the rising of its internal resistance during the last stage of its continuous discharging. |
