This article is dedicated to the investigation of sulfatation process of negative active mass. The authors showed a dependence of sulfatation degree of lead electrode from time of keeping in discharged station. It was studied the influence of addition of ammonium sulfate on desulfatation process.

The most important structural and physicomechanical properties of absorbent glass mat separators «Hollingswoth and Vose», «Bernard Dumas», «BMSK AT Nippon» intended for lead-acid battery (LAB) are studied. It is shown that on pore size distribution strong influence puts the enclosed pressure: at compression 50 kPa there is a considerable reduction of the size of a pore. However for the separation material «BMSK AT Nippon» the share of pores with radius from 5 to 10 microns is much higher, than for the separation materials «Hollingswoth and Vose» and «Bernard Dumas».
