Title (EN) LEAD ACID BATTERY
(FR) BATTERIE AU PLOMB-ACIDE
(JA) 鉛蓄電池
Abstract:
(EN) [Solution] A lead acid battery provided with a negative electrode plate and a positive electrode plate. The negative electrode plate is provided with a negative electrode current collector, and a negative electrode electrode material containing a carbon material. The carbon material includes a first carbon material having a particle size of not less than 32 μm and a second carbon material having a particle size of less than 32 μm. The ratio R2/R1 of a powder resistance R2 of the second carbon material to a powder resistance R1 of the first carbon material is not less than 15 and not more than 155. The negative electrode current collector comprises a Pb alloy including more than 0.06 mass% and not more than 0.15 mass% of Ca and not less than 0.10 mass% and not more than 0.80 mass% of Sn.
(FR) La solution selon l'invention porte sur une batterie au plomb-acide comprenant une plaque d'électrode négative et une plaque d'électrode positive. La plaque d'électrode négative comprend un collecteur de courant d'électrode négative et un matériau d'électrode d’électrode négative contenant un matériau carboné. Le matériau carboné comprend un premier matériau carboné ayant une taille de particule supérieure ou égale à 32 µm et un second matériau carboné ayant une taille de particule inférieure à 32 µm. Le rapport R2/R1 d'une résistance à la poudre R2 du second matériau carboné à une résistance à la poudre R1 du premier matériau carboné est supérieure ou égale à 15 et inférieur ou égal à 155. Le collecteur de courant d'électrode négative comprend un alliage de Pb comprenant plus de 0,06 % en masse et pas plus de 0,15 % en masse de Ca et pas moins de 0,10 % en masse et pas plus de 0,80 % en masse de Sn.
(JA) 【解決手段】鉛蓄電池は、負極板と、正極板と、を備える。前記負極板は、負極集電体と、炭素材料を含有する負極電極材料とを備える。前記炭素材料は、32μm以上の粒子径を有する第1炭素材料と、32μm未満の粒子径を有する第2炭素材料と、を含む。前記第1炭素材料の粉体抵抗R1に対する、前記第2炭素材料の粉体抵抗R2の比:R2/R1が15以上155以下である。前記負極集電体は、0.06質量%を超え0.15質量%以下のCaおよび0.10質量%以上0.80質量%以下のSnを含むPb合金で構成されている。
