Colloidally synthesized Cu3VS4 nanocrystals as a long cycling anode material for sodium-ion batteries

[Display omitted] •Colloidally synthesized Cu3VS4 are demonstrated as a sustainable anode material for Na-ion battery anodes.•The prepared anodes showed extended cycling stability up to 1000 cycles.•Operando XRD analysis shows the reformation of crystalline Cu3VS4 during the initial cycle, with amorphous transition thereafter. We report on the colloidal synthesis of Cu3VS4 nanocrystals as an earth abundant anode material for sodium-ion battery applications. The nanocrystals were structurally characterized prior to testing in half-cells, where they displayed excellent cycling stability up to 1000 cycles, demonstrating the potential of colloidally synthesised materials for sustainable battery applications.
