板の特性向上を目的としたものである。However, these additives alone have not been sufficient to improve the hydrophilicity and liquid absorption properties of the negative electrode plate required for sealed lead-acid batteries, which have been rapidly developed in recent years, that is, batteries in which the amount of electrolyte is small and limited. The present invention aims to solve these problems and improve the characteristics of a negative electrode plate.
