A polyaniline-coated Ni–Co Prussian blue analogue nanocube-modified separator for high-performance lithium–sulfur batteries

A PANi-coated Ni–Co-based Prussian blue analogue (NCP@PANi) was synthesized through a simple coprecipitation and in situ oxidation polymerization method. The NCP@PANi-modified separators can inhibit the polysulfide shuttling effectively.
