Title
(EN) LEAD STORAGE BATTERY
(FR) BATTERIE DE STOCKAGE AU PLOMB
(JA) 鉛蓄電池
Abstract
(EN)
This lead storage battery is provided with: a polar plate group in which a plurality of positive electrode plates and a plurality of negative electrode plates are laminated via separators; a cell compartment in which the polar plate group is housed; and an electrolytic solution. The electrolytic solution contains Na at a concentration of 0.03-0.3 mol/L. When two positive electrode plates or negative electrode plates (end plates) that are situated at respective ends of the polar plate group are disposed so as to come close to the inner wall of the cell compartment, an inter-electrode gap W that is determined by W=(L-d1)/N-d2 falls between -0.1 and +0.15, wherein: L represents the maximum clearance between the respective surfaces of the end plates facing the inner wall of the cell compartment; d1 represents a sum of the thickness of the positive electrode plates and negative electrode plates in the polar plate group; N represents the number of inter-electrode intervals within the cell compartment; d2 represents the total thickness of the separators interposed between the respective positive electrode plates and negative electrode plates. Each of the separators is provided with a first rib disposed on the side facing a negative electrode plate.

L'invention concerne une batterie de stockage au plomb comprenant : un groupe de plaques polaires dans lequel une pluralité de plaques d'électrode positive et une pluralité de plaques d'électrode négative sont stratifiées par l'intermédiaire de séparateurs ; un compartiment de cellule dans lequel est logé le groupe de plaques polaires ; et une solution électrolytique. La solution électrolytique contient Na à une concentration de 0,03 à 0,3 mol/L lorsque deux plaques d'électrode positive ou plaques d'électrode négative (plaques d'extrémité) qui sont situées aux extrémités respectives du groupe de plaques polaires sont disposées de façon à se rapprocher de la paroi interne du compartiment de cellules, un espace inter-électrodes W qui est déterminé par W = (L-d1)/N-d2 se situe entre -0,1 et +0,15, où : L représente l'espace maximal entre les surfaces respectives des plaques d'extrémité faisant face à la paroi interne du compartiment de cellule ; d1 représente une somme de l'épaisseur des plaques d'électrode positive et des plaques d'électrode négative dans le groupe de plaques polaires ; N Représente le nombre d'intervalles inter-électrodes à l'intérieur du compartiment de cellule ; d2 représente l'épaisseur totale des séparateurs interposés entre les plaques d'électrode positive respectives et les plaques d'électrode négative. Chacun des séparateurs comprend une première nervure disposée sur le côté faisant face à une plaque d'électrode négative.
