Original Abstract

Our contribution deals with the laser microscopy observation of the negative electrode for lead-acid batteries during their lifespan. Electrode with pasted negative active mass was optimized for cycling in opto std electrochemical cell by EL-CELL. Crystal growth and changes of electrode surface during cycling were observed using a confocal microscope Olympus Lext OLS4100. We evaluate the surface changes and sulfate crystal growth during deep cycling. The cycling mode leads to fast gradual degradation of the negative electrode – mostly because of irreversible sulfation.
