Mercury-free alkaline dry battery |
| abstract |
The present invention provides a mercury-free alkaline dry battery in which a utilization ratio of zinc as a negative electrode active material is increased to improve a discharge characteristic, the mercury-free alkaline dry battery including: a positive electrode; a negative electrode; and a separator, wherein almond-shaped zinc particles 21 are contained as a negative electrode active material. Each of the almond-shaped zinc particles 21 has a length of 1 mm to 50 mm in a long axis direction, both inclusive, and one of ends of the almond-shaped zinc particle in the long axis direction constitutes an acute end. |
