Abstract:The development of a high-performance anode is critical for the design of ultrahigh-capacity lithium-ion batteries to participate in next-generation energy-storage devices. However, the delocalization transition and sluggish reaction kinetics during TiNb 2 O 7 (TNO) relithiation lead to its low rate performance and rapid capacity decay. In this work, the ball-milling method and plasma technology are used to construct TNO nanocomposites in which defect-rich TNO particles are tightly encapsulated by an amorphous… 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.
