Abstract

Outside Back Cover:In the work in doi:10.1002/idm2.12135, a core-shell SnS₂@sulfurized polyacrylonitrile (SPAN) composite is developed by encapsulating ultrasmall SnS₂ nanocrystals in SPAN via a coaxial electrospinning technique. The one-dimensional ductile SPAN skeleton offers mass binding sites, shortens ion diffusion path and accommodates the large volume changes of SnS₂ during potassiation/depotassiation processes, thus enhancing its cyclic stability and rate capability for potassium-ion batteries.
