MANGANESE DRY CELL

摘要

A manganese dry battery of the invention includes a positive electrode material mixture including manganese dioxide, a negative electrode zinc can with a lead content equal to or less than 0.03% by weight, and a separator comprising a paper with a paste material applied thereto. The separator contains 0.005 to 0.05 part by weight of bismuth in the form of BiCl 3 per 100 parts by weight of a dry solid component in the paste material. It is thus possible to obtain a manganese dry battery that uses a negative electrode zinc can with a reduced lead content and exhibits excellent high-rate discharge performance and storage performance.
