Title (EN) LEAD ACID STORAGE BATTERY
(FR) BATTERIE DE STOCKAGE AU PLOMB-ACIDE
(JA) 鉛蓄電池
Abstract:
(EN) This lead acid storage battery is provided with: a positive electrode plate which comprises a collector and a positive electrode material that is supported by the collector; and a negative electrode plate. The total pore volume per unit mass of the positive electrode material is 0.167 cm3/g or less. The positive electrode material contains fibers; and the average specific surface area of the fibers as determined by a BET method that uses a krypton gas as an adsorption gas is 0.25 m2/g or more.
(FR) L'invention concerne une batterie de stockage au plomb-acide comprenant : une plaque d'électrode positive qui comprend un collecteur et un matériau d'électrode positive qui est supporté par le collecteur ; et une plaque d'électrode négative. Le volume poreux total par masse unitaire du matériau d'électrode positive est inférieur ou égal à 0,167 cm3/g. Le matériau d'électrode positive contient des fibres ; et la surface spécifique moyenne des fibres telle que déterminée par un procédé BET qui utilise un gaz krypton en tant que gaz d'adsorption est supérieure ou égale à 0,25 m2/g.
(JA) 鉛蓄電池は、集電体と集電体に支持された正極材料とを有する正極板と、負極板とを備える。正極材料の単位質量あたりの全細孔容積は、0.167cm/g以下である。正極材料は、繊維を含有しており、クリプトンガスを吸着ガスとして用いたBET法による繊維の平均比表面積は、0.25m/g以上である。
