摘要
The influence of the initial amount of H2SO4 added to lead powder on the phase compositions of plates in the cured and formed states has been studied. IR spectra, X-ray diffraction, scanning electron microscope observations, and wet-chemical analysis are used as techniques of investigation. It was found that the phase composition of the paste depends on the H2SO4:oxidized lead powder ratio. In addition, it is found that alpha- and beta-PbO2 are formed in the lead/acid battery positive plate from 3PbO.PbSO4.H2O. The amounts of these two compounds were strongly affected when varying the quantity of H2SO4 with respect to the lead powder.
