Three‐Dimensional SnS₂ Nanoarrays with Enhanced Lithium‐Ion Storage Properties

Abstract

Abstract Three‐dimensional (3D) SnS 2 nanoarrays were obtained by oriented‐growth of nanosheets on 3D porous carbon substrates derived from Co‐based zeolitic imidazolate framework, ZIF‐67. With the structure advantages of shortened ion diffusion length, high stress relief volume and enhanced conductivity, the 3D SnS 2 nanoarrays display favorable lithium‐ion storage properties, possessing a high reversible capacity (658 mAh g −1 at 100 mA g −1 , after 100 cycles) and outstanding rate property (651 mAh g −1 at 3 A g −1 ). This strategy paves a method for designing other 3D metal sulfides nanoarrays for energy storage application.
