shuttle effectLithium–sulfur (Li–S) battery has emerged as one of the most promising next‐generation energy‐storage systems. However, the shuttle effect greatly reduces the battery cycle life and sulfur utilization, which is great deterrent to its practical use. This paper reviews the ...
Lithium–sulfur (LiS) battery has been considered as one of the most promising rechargeable batteries among various energy storage devices owing to the attractive ultrahigh theoretical capacity and low cost. However, the performance of LiS batteries is still far from theoretical prediction because of ...
The commercialization of Li-S battery is hindered by poor conductivity of sulfur, shuttle effect and slow reaction kinetics [163]. 5.1.1 Application MOFs materials are efficient sulfur adsorbents and reaction accelerators [164,165]. There are often abundant hydrophilic adsorption sites on the surface...
“shuttle effects” of soluble intermediate polysulfides during battery operation. Polysulfides bridge the solid insulating sulfur and lithium sulfide (Li2S), and partially mitigate the high resistance and sluggish electrochemical reactions of pure solid sulfur. However, transport of polysulfides away from ...
effectbehaviorWe apply the state-of-the-art many-body dispersion (MBD) method to study the anchoring behavior in lithium-sulfur (Li–S) batteries, which is closely related to the notorious "shuttle effect". Based on the experimental results of metal sulfides (FeS and SnS), we find that ...
Early lithium-sulfur (Li-S) batteries did not perform well because sulfur species (polysulfides) dissolved into the electrolyte, causing its corrosion. This polysulfide shuttling effect negatively impactsbattery lifeand lowers the number of times the battery can be recharged. ...
