MANGANESE DRY CELL, AND NEGATIVE ELECTRODE ZINC CAN FOR MANGANESE DRY CELL

摘要

PROBLEM TO BE SOLVED: To provide a manganese dry cell having a negative electrode zinc can superior in corrosion resistance.;SOLUTION: Added elements other than zinc are precipitated in crystal grain boundary of zinc to constitute the negative electrode zinc can 4. The added elements are made of at least one kind of element selected from Pb, Bi, Ca, Mg, Si, Al, In. Furthermore, the zinc can 4 is formed by cooling molten zinc containing added elements at a cooling speed of 75-100°C/sec to diecast a zinc plate and the cast zinc plate is formed in the can by impact molding at a temperature of 20-30°C.;COPYRIGHT: (C)2008,JPO&INPIT
