Abstract
A negative electrode for an aqueous electrolyte cell disclosed in the present application contains an electrolytic zinc foil as an active material layer. The electrolytic zinc foil is preferably composed of zinc alloy containing Bi in a proportion of 0.001 to 0.2% by mass. A sheet-type cell disclosed in the present application includes a sheet-type outer case and a power generation element contained in the sheet-type outer case. The power generation element includes a positive electrode, a negative electrode, a separator, and an aqueous electrolyte solution. The negative electrode is the negative electrode for an aqueous electrolyte cell of the present application.
