Abstract Despite their high theoretical energy density, lithium–sulfur (Li–S) batteries are hindered by practical challenges including sluggish conversion kinetics and shuttle effect of polysulfides. Here, a nitrogen‐doped continuous porous carbon (CPC) host anchoring monodispersed sub‐10 nm FeS 2 nanoclusters (CPC@FeS ) is reported as an efficient catalytic matrix for sulfur cathode. This shows strong adsorption polysulfides, promising the inhibition polysulfide promoted initial stage...
