Original Abstract

Surface visualization of a negative lead-acid battery electrode during charging and discharging using atomic force microscopy was performed. To accommodate the fine resolution of AFM and inability to follow rough surfaces of the regular negative active mass real battery electrode, a smooth lead metal electrode was used. The focus was on the role of expanders on growth and dissolution of lead sulfate crystals. In one series of experiments was studied the effect of glass fibers embedded by pressure in the lead surface. The other series of experiments involved also glass fibers, but with the surface treated by commercial additive Indulin AT. It was observed that Indulin AT suppresses formation of the passivation layer on the electrode. On the other hand it causes higher polarization resistance of the electrode and reduces charge acceptance during charging.
