NiS2 nanosheet arrays on stainless steel foil as binder-free anode for high-power sodium-ion batteries

文献摘要：

Owing to the wide range and low cost of sodium resources,sodium-ion batteries(SIBs)have received extensive attention and research.Metal sulfides with high theoretical capacity are used as promising anode materials for SIBs.This paper presents the electrochemical performance of the binder-free NiS2 nanosheet arrays grown on stainless steel(SS)substrate(NiS2/SS)using an in situ growth and sulfidation strategy as anode for sodium ion batteries.Owing to the close connection between the NiS2 nanosheet arrays and the SS current collector,the NiS2/SS anode demonstrates high rate capability with a reversible capacity of 492.5 mAh·g-1 at 5.0C rate.Such rate capability is superior to that of NiS2 nanoparticles(NiS2/CMC:41.7 mAh·g-1 at 5.0C,NiS2/PVDF:7.3 mAh·g-1 at 5.0C)and other Ni sulfides(100-450 mAh·g-1 at 5.0C)reported.Furthermore,the initial reversible specific capacity and Coulombic effi-ciency of NiS2/SS are 786.5 mAh·g-1 and 81％,respec-tively,demonstrating a better sodium storage ability than those of most NiS2 anodes reported for SIBs.In addition,the amorphization and conversion mechanism during the sodiation/desodiation process of NiS2 are proposed after investigation by in situ X-ray diffraction(XRD)measurements of intermediate products at successive charge/discharge stages.
