Abstract
(EN)
Provided is a lead storage battery in which an increase in internal resistance is minimized and in which it is possible to accurately determine the charging state or the degradation state by a method in which the internal resistance is measured. A lead storage battery comprising an electrode plate group (1) in which a plurality of positive electrode plates (10) having a lead-dioxide-containing positive electrode active material and a plurality of negative electrode plates (20) having a metal-lead-containing negative electrode active material are stacked in an alternating manner with separators (30) interposed therebetween. The electrode plate group (1) is immersed in an electrolytic solution. The post-chemical-conversion flatness of the positive electrode plates (10) is 4.0 mm or below.

L'invention concerne une batterie au plomb dans laquelle une augmentation de la résistance interne est minimisée et dans laquelle il est possible de déterminer avec précision l'état de charge ou l'état de dégradation par un procédé dans lequel la résistance interne est mesurée. Une batterie au plomb comprend un groupe d'électrodes planes (1) dans lequel une pluralité d'électrodes planes positives (10) ayant un matériau actif d'électrode positive contenant du dioxyde de plomb et une pluralité d'électrodes planes négatives (20) ayant un matériau actif d'électrode négative contenant du plomb métallique sont empilées de manière alternée, des séparateurs (30) étant intercalés entre elles. Le groupe d'électrodes planes (1) est immergé dans une solution électrolytique. La planéité post-conversion chimique des électrodes planes positives (10) est inférieure ou égale à 4,0 mm.
