Electrochemically induced phase transition in a nanoflower vanadium tetrasulfide cathode for high-performance zinc-ion batteries
文献摘要：
Aqueous zinc-ion batteries(AZIBs)are promising contenders for large-scale energy storage with the mer-its of their low cost,high safety,environmental friendliness,and competitive gravimetric energy density.Nevertheless,suitable cathode materials with long cycle life and adequate capacity are still rare.Herein,we report a nanoflower vanadium tetrasulfide/carbon nanotubes(VS4/CNTs)cathode with high Zn-storage performance.We propose a phase transition reaction mechanism from VS4 to zinc pyrovanadate in the initial cycles and a reversible intercalation mechanism for Zn2+in zinc pyrovanadate during sub-sequent cycles.As a result,the cathode delivers a high discharge capacity of 265 mAh g-1 at 0.25 A g-1 and 182 mAh g-1 at 7 A g-1.In addition,the cathode exhibits a long-term cyclability with 93％capacity retention over 1200 cycles at 5 A g-1.VS4/CNTs with superior electrochemical performance is a hopeful cathode material in AZIBs.
