摘要： A manganese dry battery with excellent leak-proof property is provided, in which electrolyte leakage does not occur even if the size of a positive electrode material mixture is increased to meet a demand for improvement in discharge property. In a sealing part, a first circular projection, a second circular projection and a third circular projection are arranged at the bottom in sequence from the center to the outside, and a positive electrode carbon rod supporting part is provided in an innermost periphery portion to have an interval from the first circular projection. A groove between the first projection and the carbon rod is formed to have a substantially rectangular vertical section, kraft board is pressed by flat bottom surfaces of the first and second projections and an opening of the zinc can is fitted between the second and third projections.

摘要： The positive electrode current collector for a manganese dry battery of the present invention comprises a carbon rod, and either one of a paraffin wax containing hydrocarbon whose molecular weight is 300 to 500 and a microcrystalline wax containing hydrocarbon whose molecular weight is 500 to 800, which is impregnated into the carbon rod, is characterized in that the endothermic amount of the paraffin wax or the microcrystalline wax obtained by differential scanning calorimetry up to 45° C. is not more than 1.0 J/g.This enables the manganese dry battery employing the positive electrode current collector of the present invention to keep its sealing performance in a good condition during high-temperature storage even with the use of a low-density carbon rod.

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 BiCl3 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.
