Abstract:Mechanical deformation in battery electrodes incites degradation and capacity loss by causing cracks in the active material, electrical isolation of particles from the current collector, and additional surface area available for electrolyte decomposition. Surface (stress) and bulk (strain) mechanical changes occur asynchronously, and increasing our understanding of their individual contributions to deformation can aid in the design of more robust and longer-lasting batteries. One method with which to compare t… 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.
