MANGANESE DIOXIDE AND ALKALINE DRY BATTERY |
摘要 |
Disclosed is manganese dioxide having a peak intensity ratio between a peak intensity Iβ in a vicinity of 525 cm−1 and a peak intensity Iγ in a vicinity of 580 cm−1: Iβ/Iγ of 0.62 or less, when measured by Raman scattering spectroscopy. Also disclosed is an alkaline dry battery comprising: a cylindrical positive electrode having a hollow, the positive electrode including the foregoing manganese dioxide; a gelled negative electrode including a negative electrode active material filled in the hollow of the positive electrode; a separator disposed between the positive electrode and the gelled negative electrode; a negative electrode current collector inserted in the gelled negative electrode; a negative terminal plate electrically connected to the negative electrode current collector; and an electrolyte. |
