Synergistic polysulfide regulation and lithium deposition enabled by core–shell Ag/Ag2S heterostructured fabric
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.
