Anode cup made of Ag-Zn or Ag-Zn-Ti alloy for dry manganese battery

摘要

A manganese dry battery includes a cathode manganese dioxide. an anode zinc can and a separator, wherein the anode zinc can is made of a zinc alloy free from lead and containing 0.003 - 0.5 wt% of silver. Even without heavy metals such as Hg, Cd and particularly Pb, the zinc alloy anode can has a corrosion-resistant property and mechanical strength equivalent to or greater than those of the conventional zinc anode can, thereby giving a low pollution zinc-carbon battery having a storage characteristic equivalent or superior to that of the conventional zinc anode can.
