  • Lithium-sulfur batteries are widely seen as a promising next-generation energy storage system owing to their ultrahigh energy density and environmental benignity, yet the low electrical conductivity of sulfur and the shuttle effect of dissolved polysulfides result in poor cycling performance. An a-MEGO@g-C3N4composite coated on polypropylene separator with high nitrogen content (atomic percent 20.08%) and specific surface area (1000 m2·g-1) was developed to inhibit polysulfide shuttling. The prepared lithium-sulfur battery with the a-MEGO@g-C3N4 coated separator delivered a specific capacity
