Abstract
Abstract Tin diselenide, a promising anode material for sodium ion batteries (SIBs), still faces sluggish Na + diffusion kinetics and severe volume change, resulting in undesirable cycling stability and rate capability. Heterostructure construction is an effective strategy for boosting Na + storage of SnSe 2 . Herein, an appealing yolk‐shell nanostructure of SnSe 2 /NiSe 2 heterointerface with rich Se vacancies embedded into N‐doped carbon (SnSe 2 /NiSe 2 @NC) is precisely designed through a facile hydrothermal process followed by a selenization strategy. The experimental studies coupled with theoretical calculations results verify that the heterostructure interfaces and Se vacancies accelerate the charge and…
