Facile Synthesis of MPS 3 /C (M = Ni and Sn) Hybrid Materials and Their Application in Lithium-Ion Batteries

Herein, we successfully synthesized two novel metal thiophosphites (MTPs) hybridized with carbon, that is, NiPS /C and SnPS /C composites, via an environment-friendly and cost-effective approach without harsh reaction conditions. Subsequently, the electrochemical performances of NiPS /C and SnPS /C...

Description
Summary:Herein, we successfully synthesized two novel metal thiophosphites (MTPs) hybridized with carbon, that is, NiPS /C and SnPS /C composites, via an environment-friendly and cost-effective approach without harsh reaction conditions. Subsequently, the electrochemical performances of NiPS /C and SnPS /C composites have been investigated in coin-cells, and it is revealed that MTPs/C have a significantly higher Li-storage capacity and better stability compared to the MTPs without carbon. Moreover, the SnPS /C electrode shows a lower internal resistance and a better rate performance compared to NiPS /C. We employed extensive ex situ experiments to characterize the materials and interpreted the remarkably improved performance of MTPs/C.
