摘要

In this work, gibbsite and boehmite were used as additives of gel valve regulated lead acid battery forthe first time in the literature. Optimum amounts of additives were determined as 0.6wt% for eachspecies by using of cyclic voltammetric and electrochemical impedance spectroscopic methods. Whileanodic peak currents and capacities increased by using of additives, charge transfer resistancesdecreased. Polarization curves were obtained to determine the effects of additives on the corrosionbehaviors of fumed silica based gelled electrolytes. Gel systems consisting of additives showed lowercorrosion tendency than those of non-gelled electrolyte and fumed silica based gelled electrolyte. Thesurface changes of lead electrodes were also analyzed at the end of the 100 voltammetric cycle byscanning electron microscopy. The pictures also supported anti-corrosion (anti-sulfation) effects ofadditives. These novel additives can be used for manufacturing of fumed silica based gelled electrolyteof valve regulated lead acid batteries.
