Title (EN) LEAD STORAGE BATTERY
(FR) ACCUMULATEUR AU PLOMB
(JA) 鉛蓄電池
Abstract:
(EN) The present disclosure pertains to a lead storage battery that comprises a battery jar having a cell chamber, an electrode plate group that is provided in the cell chamber and that comprises a separator and a positive plate and a negative plate that are alternately stacked via the separator, and an electrolytic solution housed in the cell chamber. The positive plate and the negative plate, respectively, comprise an electrode material filler portion formed from an electrode material, a collector that supports the electrode material filler portion, and a lug portion provided on an upper peripheral section of the collector. When setting the total surface area of the electrode material filler portion as S1 and when setting the apparent total volume of the electrode material filler portion as V1, S1/V1 is at least 8.9 cm-1, and when setting the mass of a positive electrode material as p1 and when setting the mass of a negative electrode material as n1, p1/n1 is at least 1.35.
(FR) La présente invention concerne un accumulateur au plomb qui comprend un bac d'accumulateur comportant une chambre de cellules, un groupe de plaques d'électrode qui est agencé dans la chambre de cellules et comprend un séparateur et une plaque positive et une plaque négative qui sont empilées en alternance par l'intermédiaire du séparateur, ainsi qu'une solution électrolytique logée dans la chambre de cellules. La plaque positive et la plaque négative comportent, respectivement, une partie de charge de matériau d'électrode formée à partir d'un matériau d'électrode, un collecteur qui supporte la partie de charge de matériau d'électrode, et une partie languette disposée sur une section périphérique supérieure du collecteur. Lorsque l'on règle la surface totale de la partie de charge de matériau d'électrode en tant que S1 et que l'on règle le volume total apparent de la partie de charge de matériau d'électrode en tant que V1, S1/V1 représente au moins 8,9 cm-1, et lorsque l'on règle la masse d'un matériau d'électrode positive en tant que p1 et que l'on règle la masse d'un matériau d'électrode négative en tant que n1, p1/n1 représente au moins 1,35.
(JA) 本開示は、セル室を有する電槽と、セル室内に設けられており、セパレータとこのセパレータを介して交互に積層された正極板及び負極板とを有する極板群と、セル室内に収容された電解液とを備えた鉛蓄電池に関する。正極板及び負極板は、それぞれ、電極材によって構成される電極材充填部と、電極材充填部を支持する集電体と、集電体の上部周縁部に設けられた耳部とを有する。電極材充填部の総表面積をS1とし、電極材充填部の見かけ総体積をV1とすると、S1/V1は8.9cm-1以上であり、正極材の質量をp1とし、負極材の質量をn1とすると、p1/n1は1.35以上である。
