Porosity measurements of positive of lead-acid battery plates by mercury psorosimetry

Abstract EN

A mercury porosimeter has been used to measure the intrusion volume of the three type’s mercury positive lead acid-battery plates.

The intrusion volumes were used to calculate the pore diameter, pore volume, pore area, and pore size distribution.

The variation of the pore area in positive lead acid-battery plates as well as of the pore volume has the following sequence.

Paste positive > Uncured positive > Cured positive.
