Metal-organic framework(MOF)-derived selenidation strategy to prepare porous(Zn,Cu)CoSex micro/nanostructures for sodium-ion batteries
文献摘要:
Owning to the wide distribution,low cost,and similar chemical-electrochemical properties with lithium,sodium-ion batteries(SIBs)have attracted much attention during recent years and may have the potential to replace the commercial lithium-ion batteries.Herein,facile and simple bottom-up approach has been rationally applied to fabricate carbon-encapsulated ZnSe@CoSe2 microspheres and Cu2Se@CoSe2 nanocubes.The as-prepared ZnSe@-CoSe2 microspheres and Cu2Se@CoSe2 nanocubes com-posites inherited the original structure of ZnCo-MOF and CuCo-MOF,respectively.Herein,both ZnSe@CoSe2 microspheres and Cu2Se@CoSe2 nanocubes delivered excellent electrochemical performance when presented as anode materials for SIBs.Both ZnSe@CoSe2 microspheres and Cu2Se@CoSe2 nanocubes electrode could display a long-term cycling stability with a reversible capacity of 525 and 423 mAh·g-1 at the current density of 1 A·g-1 after 500 cycles,respectively.Furthermore,even at a high current density of 5 A·g-1,ZnSe@CoSe2 microsphere could still maintain 520 mAh·g-1 after 500 cycles,demonstrating remarkable capacity and excellent cycling performance.Those high performances were beneficial from the unique hollow and porous structure of ZnSe@CoSe2 microspheres and Cu2Se@CoSe2 nanocubes derived from the precursor which facilitate the transport of sodium ions,contributing to high capacity,improved excellent cycle stability and rate capability.
