Abstract:
A heterostructured Ag/Ag2S nanofiber embedded in nitrogen-doped carbon (Ag/Ag2S@NC) electrospun fabrics served as a dual regulator on both the sulfur cathode and lithium anode for lithium-sulfur (Li-S) batteries, delivering stable cycling with 86.3% capacity retention over 400 cycles at 1C.
