Synthesis of hexahedron SnS2/C derived from tin metal-organic frameworks (Sn-MOF) as a promising anode for lithium-ion batteries

Abstract The SnS2/C composite (nanoflower SnS2 embedded in hexahedron carbon skeleton) was obtained by a novel solid-state method using the Sn-MOF as the precursor. Different from the previous solid-state method, this work adopts a facile strategy of a double temperature zone. The synthesized composite exhibits an outstanding capacity of 847.9 mAh g−1 after 100 cycles at a current density of 0.1 A g-1, which could be considered as a promising anode material for lithium-ion batteries. The high-capacity retention and excellent rate performance were confirmed by further electrochemical examination.
