Porosity Measurements of Positive of Lead-Acid Battery Plates by Mercury PSorosimetry

الملخص

A mercury porosimeter has been used to measure the intrusion volume of the three types 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
