Abstract
(EN)
A lead acid storage battery 100 according to the present invention is provided with a positive electrode 10 that comprises: an active material holding member 50 which is provided with a tube 52 that holds an active material; and an active material which is held by the tube 52. With respect to the active material holding member 50, the tube 52 has one end part 52a, the other end part 52b, and an intermediate part 52c that is positioned between the one end part 52a and the other end part 52b. This lead acid storage battery 100 has an embodiment wherein the compressive strength of the one end part 52a is higher than the compressive strength of the intermediate part 52c, or an embodiment wherein the compressive strength of the one end part 52a of the tube 52 is not less than 3 N/mm2.

Selon l'invention, une batterie d'accumulateurs au plomb (100) est équipée d'une électrode (10) qui possède à son tour un élément de maintien de matière active (50) équipé d'un tube (52) maintenant une matière active, et la matière active maintenue par le tube (52). Le tube (52) possédant une première partie extrémité (52a), une seconde partie extrémité (52b) et une partie intermédiaire (52c) entre la première partie extrémité (52a) et la seconde partie extrémité (52b), l'élément de maintien de matière active (50) présente soit un aspect tel que la résistance à la compression de la première partie extrémité (52a) est supérieure à la résistance à la compression de la partie intermédiaire (52c), soit un aspect tel que la résistance à la compression de la première partie extrémité (52a) du tube (52) est supérieure ou égale à 3N/mm.
(JA)
鉛蓄電池100は、活物質を保持するチューブ52を備える活物質保持部材50と、チューブ52に保持された活物質と、を有する正極10を備え、活物質保持部材50は、チューブ52が、一端部52aと、他端部52bと、一端部52a及び他端部52bの間の中間部52cと、を有し、一端部52aの圧縮強度が中間部52cの圧縮強度より高い態様、又は、チューブ52の一端部52aの圧縮強度が3N/mm以上である態様を有する。
