A POSITIVE ELECTRODE CURRENT COLLECTOR FOR A MANGANESE DRY BATTERY AND A MANGANESE DRY BATTERY USING THE SAME

摘要

To provide a positive electrode current collector for a manganese dry battery including a carbon rod with a low density yet with good retention of the sealing property of the battery during high temperature storage. The positive electrode current collector for a manganese dry battery comprises a carbon rod and paraffin wax containing a hydrocarbon compound having a molecular weight of 300 to 500 impregnated in the carbon rod, the paraffin wax containing a hydrocarbon compound having a molecular weight of not greater than 310 in an amount of not greater than 0.5 wt %.
