✦ Synopsis

A scanning electron microscope investigation of the structure of the reduced Pb/PbS0 4 electrode revealed that lignin prevented the extensive growth of dendritic lead single crystals that occurred in its absence . It was further shown that the smooth surfaced, large diameter dendritic branches, present in additive-free electrodes were replaced by smaller. more uniform, rough surfaced and porous particles in the presence of lignin . No significant changes' occurred in the lead structure when RaSO, alone was added . Lignin and BaSO,,, used together, produced a lead structure with greater surface urea rind porosity than did lignin alone .
