Abstract
In an alkaline battery in which 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 is sealed with a gasket 5, a half-width of a 110 plane peak of the manganese dioxide measured by a powder X-ray diffraction analysis is in the range of 1.80-2.40 degrees, and anatase titanium dioxide is contained in the positive electrode such that a ratio of anatase titanium dioxide to the positive electrode is in the range of 0.10-1.50 mass %.
Claims4
An alkaline battery in which a positive electrode containing manganese dioxide, a negative electrode, and a separator interposed therebetween are housed in a closed-end cylindrical battery case whose opening is sealed with a gasket, wherein
- a half-width of a 110 plane peak of the manganese dioxide measured by a powder X-ray diffraction analysis is in the range of 1.80-2.40 degrees, and
- anatase titanium dioxide is contained in the positive electrode such that a ratio of anatase titanium dioxide to the positive electrode is in the range of 0.10-1.50 mass %.
