Abstract:The
efficient operation of metal-ion batteries in harsh environments,
such as at temperatures below −20 °C or at high charge/discharge
rates required for EV applications, calls for a careful selection
of electrode materials. In this study, we report advantages associated
with the solid solution (de)intercalation over the two-phase (de)intercalation
pathway and identify the main sources of performance limitations originating
from the two mechanisms. To isolate the (de)intercalation pathway
as the main variable,… 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.
