Title (EN) ALKALINE DRY CELL
(FR) PILE SÈCHE ALCALINE
(JA) アルカリ乾電池
Abstract:
(EN) This alkaline dry cell is provided with: a bottomed cylindrical cell case; a positive electrode filled into the cell case and constituted by a stack of n hollow cylindrical pellets; a negative electrode disposed within the hollow portion of the pellets; a separator disposed between the positive electrode and the negative electrode; and an alkaline electrolyte. The thickness of the body of the cell case is 0.08-0.16 mm. n is an integer greater than or equal to 3. The average density of manganese dioxide in the n pellets is 2.80-3.00 g/cm3. The density of manganese dioxide in at least one pellet positioned midway in the height direction of the stack does not exceed 2.75 g/cm3.
(FR) La pile sèche alcaline de l'invention est équipée : d'une enveloppe de pile en forme de cylindre avec un fond; d'une électrode positive qui remplit l'enveloppe de pile, et qui est configurée par un empilement de n pastilles en forme de cylindre creux; d'une électrode négative placée à l'intérieur de la partie creuse des pastilles; d'un séparateur placé entre l'électrode positive et l'électrode négative; et d'un électrolyte alcalin. L'épaisseur d'une partie corps de l'enveloppe de pile, est comprise entre 0,08 et 0,16mm. n équivaut à un nombre entier supérieur ou égal à 3, la concentration moyenne de dioxyde de manganèse dans les n pastilles, est comprise entre 2,80 et 3,00g/cm3, et la concentration en dioxyde de manganèse dans au moins une pastille positionnée au niveau d'une partie centrale dans la direction de la hauteur de l'empilement, est inférieure ou égale à 2,75g/cm3.
(JA) アルカリ乾電池は、有底円筒形の電池ケースと、電池ケースに充填され、かつn個の中空円筒形のペレットのスタックで構成された正極と、ペレットの中空部内に配された負極と、正極と負極との間に配されたセパレータと、アルカリ電解液と、を備える。電池ケースの胴体部の厚みは、0.08~0.16mmである。nは3以上の整数であり、n個のペレットにおける二酸化マンガンの平均密度は、2.80~3.00g/cm3であり、スタックの高さ方向の中央部に位置する少なくとも1つのペレットにおける二酸化マンガンの密度は、2.75g/cm3以下である。
