Abstract
(EN) The negative electrode for aqueous electrolytic solution batteries according to the present invention includes an electrolytic zinc foil as an active material layer. The electrolytic zinc foil is preferably formed from a zinc alloy containing Bi at a proportion of 0.001-0.2 mass%. The sheet-like battery according to the present invention includes a sheet-like exterior body and a power generation element housed in the sheet-like exterior body. The power generation element includes a positive electrode, a negative electrode, a separator, and an aqueous electrolytic solution, wherein the negative electrode is said negative electrode for aqueous electrolytic solution batteries according to the present invention.
(FR) L'électrode négative pour batteries à solution électrolytique aqueuse selon la présente invention comprend une feuille de zinc électrolytique comme couche de matériau actif. La feuille de zinc électrolytique est de préférence formée à partir d'un alliage de zinc contenant Bi à une proportion de 0,001 à 0,2 % en masse. La batterie de type feuille selon la présente invention comprend un corps extérieur de type feuille et un élément de génération d'énergie logé dans le corps extérieur de type feuille. L'élément de génération d'énergie comprend une électrode positive, une électrode négative, un séparateur et une solution électrolytique aqueuse, l'électrode négative étant ladite électrode négative destinée à des batteries à solution électrolytique aqueuse selon la présente invention.
