Abstract

Abstract: In this study, we propose a facile electrospinning approach to fabricate the novel one-dimensional V3 S4 @NC nanofibers as promising anodes for sodium-ion batteries. In this composite, monoclinic-structured V3 S4 nanocrystals are uniformly embedded in one-dimensional carbon fibers with high electrical conductivity. Electrochemical tests demonstrate that the as-fabricated V3 S4 @NC anode shows outstanding rate property and good cyclic life due to its superior conductivity for electron transfer. It possesses high reversible capacities of 455, 343, 307 and 249 mAh g −1 at 0.1, 1, 2 and 5 A g −1 respectively and exhibits a 96.5% capacity retention at 10 A g −1 after 300 cycles. This promising strategy described in this work provides a novel direction for generating high-performance V3 S4 anode for sodium-ion storage. Highlights: One-dimensional V3 S4 @NC fibers have been successfully synthesized through a facile electrospinning approach for sodium energy storage. The constructed carbon fibers can enhance the electrical conductivity of V3 S4 and inhibit the volume change during cycling process. V3 S4 @NC anode shows a 96.5% capacity retention at 10 A g −1 over 300 cycles.
