Topochemically synthesized Nb3VS6 as a stable anode for sodium-ion batteries

Ternary metal sulfides having layered morphology are considered as potential active materials for various applications. Herein, Nb3VS6 is synthesized topochemically for the first time using a Nb–V–HDA complex having a lamellar structure by employing H2S gas as the sulfidation agent. Nb3VS6, as an an...

Description
Summary:Ternary metal sulfides having layered morphology are considered as potential active materials for various applications. Herein, Nb3VS6 is synthesized topochemically for the first time using a Nb–V–HDA complex having a lamellar structure by employing H2S gas as the sulfidation agent. Nb3VS6, as an anode for SIBs, exhibited a specific capacity of 101.15 mA h g−1 at 0.5 A g−1, along with excellent cycling stability with 100% capacity retention after 2500 cycles.
