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 0.08-0.14 mm. n is an integer greater than or equal to 2. The average density of manganese dioxide in the n pellets is 2.80-3.00 g/cm3. A gap is formed between at least a pair of adjacent pellets, and the width of the gap is at least 1% relative to the total height of the n pellets.
(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 0,14mm. n équivaut à un nombre entier supérieur ou égal à 2, la concentration moyenne de dioxyde de manganèse dans les n pastilles, est comprise entre 2,80 et 3,00g/cm3, et un intervalle est formé au moins entre lesdites pastilles adjacentes par paire, la largeur de cet intervalle étant supérieure ou égale à 1% par rapport au total de la hauteur desdites n pastilles.
(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、0.08~0.14mmである。nは2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、少なくとも一対の隣接する前記ペレット間に隙間が形成されており、隙間の幅は、前記n個のペレットの高さの合計に対して1%以上である。
