Because of their high energy density, low cost, and environmental friendliness, lithium–sulfur (Li–S) batteries are one the potential candidates for next-generation energy-storage devices. However, they have been troubled by sluggish reaction kinetics insoluble Li2S product capacity degradation because severe shuttle effect polysulfides. These problems overcome introducing transition metal compounds (TMCs) as catalysts into interlayer modified separator or sulfur host. This review first introduces mechanism redox reactions. The methods studying TMC in Li–S provided. Then, recent advances TMCs (such oxides, sulfides, selenides, nitrides, phosphides, carbides, borides, heterostructures) some helpful design modulation strategies highlighted summarized. At last, future opportunities toward presented.

To utilize intermittent renewable energy as well achieve the goals of peak carbon dioxide emissions and neutrality, various electrocatalytic devices have been developed. However, reactions, e.g., hydrogen evolution reaction/oxygen reaction in overall water splitting, polysulfide conversion lithium–sulfur batteries, formation/decomposition lithium peroxide lithium–oxygen nitrate reduction to degrade sewage, suffer from sluggish kinetics caused by multielectron transfer processes. Owing merits accelerated charge transport, optimized adsorption/desorption intermediates, raised conductivity, regulation microenvironment, ease combine with geometric characteristics, built-in electric field (BIEF) is expected overcome above problems. Here, we give a Review about very recent progress BIEF for efficient electrocatalysis. First, construction strategies characterization methods (qualitative quantitative analysis) are summarized. Then, up-to-date overviews engineering electrocatalysis, attention on electron structure optimization microenvironment modulation, analyzed discussed detail. In end, challenges perspectives proposed. This gives deep understanding design electrocatalysts next-generation storage devices.
