| 摘要 | In an alkaline battery, a positive electrode 2 containing manganese dioxide, a negative electrode 3, and a separator 4 interposed therebetween are housed in a closed-end cylindrical battery case 1 whose opening 1b is sealed with a gasket. The positive electrode contains graphite in such a manner that a ratio of graphite to the positive electrode is in the range of 2.5-4.3 mass %. A half-width of a 110 plane of the manganese dioxide measured by a powder X-ray diffraction analysis is in the range of 2.00-2.40 degrees. | ||
