Description
Summary:Tin sulfide (SnS) 3D flowers containing hierarchical nanosheet subunits are synthesized using a simple polyol process. The Li ion cells incorporating SnS 3D flowers exhibit an excellent rate capability, as well as good cycling stability, compared to SnS bulks and Sn nanoparticles. These desirable properties can be attributed to their unique morphology having not only large surface reaction area but also enough space between individual 2D nanosheets, which alleviates the pulverization of SnS. SnS three‐dimensional flowers containing hierarchically organized two‐dimensional nanosheet subunits derived from two approaches are devised. One suggests that the SnS flowers with a large surface area and a shortened ion diffusion pathway can increase power density. The other suggests that each nanosheet composing the flowers can effectively accommodate volume changes during cycling, which leads to enhancement of the cycle life.
