Abstract:Sn-based anodes are promising high-capacity
anode materials for
low-cost lithium ion batteries. Unfortunately, their development is
generally restricted by rapid capacity fading resulting from large
volume expansion and the corresponding structural failure of the solid
electrolyte interphase (SEI) during the lithiation/delithiation process.
Herein, heterostructural core–shell SnO2-layer-wrapped
Sn nanoparticles embedded in a porous conductive nitrogen-doped carbon
(SOWSH@PCNC) are proposed. In this design, th… 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.
