Synergistic design of core–shell V3S4@C hosts and homogeneous catalysts promoting polysulfide chemisorption and conversion for Li–S batteries

The synergistic design of 1D core–shell V 3 S 4 @C hosts and homogeneous catalyst Co(C 5 H 5 ) 2 is proposed to promote the chemisorption and conversion kinetics of polysulfides towards advanced Li–S batteries with high areal S loading and low E/S ratio.
