Title
(EN) LEAD STORAGE CELL
(FR) ACCUMULATEUR AU PLOMB
(JA) 鉛蓄電池
Abstract
(EN)
Provided is a lead storage cell that, even when employed as a drive source for a vehicle that vibrates violently, such as an electric scooter, does not give rise to sudden death due to internal short circuiting or the like, and that has excellent life characteristics. The lead storage cell has a plate group in which either a positive plate or a negative plate is encapsulated in a first separator comprising a hydrophilized synthetic fiber nonwoven fabric, the positive plate and the negative plate being disposed in opposition with the first separator and a second separator of plate form comprising glass fibers therebetween, wherein the lead storage is characterized in that the first separator has a perforation strength of 4500 gf/mm-7500 gf/mm, inclusive, per unit thickness, when measured by a rod having a semispherical tip 1 mm in diameter descending at a rate of 1 mm/second.

L'invention fournit un accumulateur au plomb dont une mort subite due à un court-circuit interne est peu probable, et dont les caractéristiques de durabilité sont excellentes, y compris dans le cas d'une mise en œuvre en tant que source d'entraînement d'un véhicule dont les vibrations sont fortes tel qu'un scooter électrique, ou similaire. Plus précisément, l'invention concerne un accumulateur au plomb dans lequel une plaque positive ou une plaque négative est encapsulée dans un premier séparateur constitué de tissu non tissé en fibre synthétique ayant été soumis à un traitement d'hydrophilisation, et qui possède un groupe de plaques mettant en opposition ladite plaque positive et ladite plaque négative par l'intermédiaire dudit premier séparateur et d'un second séparateur plat constitué de fibre de verre. Ledit premier séparateur est caractéristique en ce que sa résistance à la pénétration par unité d'épaisseur est supérieure ou égale à 4500gf/mm et inférieure ou égale à 7500gf/mm, dans le cas d'une mesure au cours de laquelle une barre possédant une extrémité avant semi-sphérique de 1mm de diamètre, est abaissée de 1mm/seconde.
