An Electrochemical Atomic Force Microscope (EC-AFM) was used to observe the surface reaction of lead electrode in sulfuric acid electrolyte, when the reaction corresponding to what occurs at the electrode of a lead-acid battery takes place. At first, the morphology change at the surface of the lead electrode during Cyclic-Voltammetry measurement could be observed by using EC-AFM. After that, behavior of PbSO4 crystals during open-circuit standing after oxidation was observed by in-situ EC-AFM, and the degradation of charge acceptance performance of lead-acid batteries during open-circuit standing after discharge could be explained by this observation result. In this paper, we introduce some technique with using EC-AFM for understanding of the electrochemical reaction at solid/liquid interface in the lead-acid battery.
