Ultrafine Ni12P5 nanoparticle-embedded carbon with abundant catalytic activity sites as separator modifiers in high-performance lithium–sulfur batteries

Ultrafine Ni 12 P 5 nanoparticle-embedded carbon nanospheres are used as separator modifiers for Li–S batteries. The uNi 12 P 5 /C//PP modified separator can effectively trap polysulfides by polar interaction and enhance the kinetic conversion of LiPSs.
