Lithium-sulfur (Li-S) batteries are promising next-generation energy storage technologies due to their high theoretical density, environmental friendliness, and low cost. However, conductivity of sulfur species, dissolution polysulfides, poor conversion from reduction, lithium sulfide (Li2S) oxidation reactions during discharge-charge processes hinder practical applications. Herein, under the guidance density functional theory calculations, we have successfully synthesized large-scale single...
Abstract Accelerated conversion by catalysis is a promising way to inhibit shuttling of soluble polysulfides in lithium–sulfur (Li–S) batteries, but most the reported catalysts work only for one direction sulfur reaction (reduction or oxidation), which still not root solution since fast cycled use species finally realized. A bidirectional catalyst design, oxide–sulfide heterostructure, proposed accelerate both reduction and oxidation insoluble discharge products (e.g., Li 2 S), indicating...
