Sb-MOFs derived Sb nanoparticles@porous carbon for high performance potassium-ion batteries anode.

Reasonable design of Sb-based nanomaterials, which can alleviate volume expansion, agglomeration and pulverization, is meaningful for PIBs. We used Sb-MOFs as precursors to perfectly and controllably embed uniform Sb nanoparticles (∼19 nm) into porous carbon networks through simple carbonization strategies and achieved excellent electrochemical performance for PIBs.
