- Alkaline dry batteries were produced in the same manner as in Example 4 and Comparative Example 4 except that this positive electrode mixture was used, and a heat cycle test was conducted. The results are shown in Table 8.
- Example 1 SAS296 13-24 0 0 0 Comparative Example 1 0 1,1-Dixylyldecane 26 0 5 7
- the alkaline dry battery of the present invention is suitably used as a power source for electronic devices such as portable devices and information devices.
