STEEL SHEET FOR FORMING BATTERY CAN WITH SUPERIOR LEAKAGE RESISTANCE AND HEAVY-LOAD DISCHARGE PERFORMANCE, ITS MANUFACTURING METHOD, BATTERY CAN, AND ALKALINE DRY CELL

摘要

PROBLEM TO BE SOLVED: To provide a steel sheet for forming a battery can equipped with both superior leakage resistance and heavy-load discharge performance (discharge performance after long term storage), its manufacturing method, a battery can, and an alkaline dry cell.;SOLUTION: This steel sheet includes: an Fe-Ni alloy plated layer or an Fe-Ni diffusion alloy layer 2 with an Fe concentration of an outermost surface layer which is a surface to be a can inner face set within the range of 10 atom% or more and 70 atom% or less; a recrystallized Ni layer 3 having a thickness of 0.2 m or more formed therebelow; and an Fe-Ni diffusion alloy layer 4 further formed therebelow.;COPYRIGHT: (C)2008,JPO&INPIT
