Electrode plate group for lead-acid battery, lead-acid battery, and method for producing electrode plate group for lead-acid battery

摘要

A grid for a lead storage battery is configured from an expanded grid formed by a reciprocal method. When the width of a grid line (g) of the expanded grid is represented by W and the thickness of the expanded grid is represented by T, the flexibility (T/W) of the grid falls within the range of 1.5-1.9.
