Abstract:Barite (BaSO4) is a common additive in lead–acid
batteries, where it acts as a nucleating agent to promote the reversible
formation and dissolution of PbSO4 during battery cycling.
However, little is known about the molecular-scale mechanisms that
control the nucleation and cyclic evolution of PbSO4 over
a battery’s lifetime. In this study, we explore the responses
of a barite (001) surface to cycles of high and low lead concentrations
in 100 mM sulfuric acid solution using in situ atomic force microscopy
and … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
