Defect engineering in Co-doped Ni3S2 nanosheets as cathode for high-performance aqueous zinc ion battery
文献摘要:
With the merits of low cost,environmental benignity,and high safety,aqueous zinc ion batteries(AZIBs)have great potential in the field of energy storage.In this paper,we craft a Co-doped Ni3S2 with abun-dant sulfur vacancies as effective cathode materials(Co-Ni3S2-x)for AZIBs by hydrothermal and chemical reduction method.Notably,cobalt doping and abundant sulfur vacancies can effectively increase the con-ductivity and the number of active sites for electrochemical reactions,which gives the Co-Ni3S2-x elec-trode the outstanding capability to energy storage.By coupling Co-Ni3S2-x cathode with Zn anodes to assemble alkaline AZIBs,the Co-Ni3S2-x//Zn full battery exhibits excellent specific capacity(183.9 mAh g-1 at 1 A g-1,based on cathode mass)and extraordinary cycling durability(72.9%capacity retention af-ter 6000 cycles).First-principles calculations based on density functional theory(DFT)confirm that the Co-Ni3S2-x electrode has strong energy storage capacity and electrochemical stability.The results provide an extremely significant reference in designs of self-supported bimetallic sulfide nanosheets,which have promising applications in high-performance energy storage devices.
