Polysulfide shuttle phenomenon

Lithium-sulfur batteries suffer from a rapid capacity decay and low energy efficiency because of the low solubility of lithium sulfide (Li2S) in organic solvents and the intrinsic polysulfide shuttle phenomenon. Phosphorus pentasulfide (P2S5) in an organic electrolyte, has been shown to boost the cycling performance of lithium-sulfur batteries. The function of the additive is two-fold (72) ... [Pg.82]

P2S5 passivates the surface of lithium metal and therefore eliminates the polysulfide shuttle phenomenon. [Pg.82]

Polysuffide shuttle is a phenomenon unique to Li-S batteries with liquid electrolytes. This phenomenon is responsible for high self-discharge, low coulombic efficiency, severe sulfur migration, and fast capacity decay. The polysulfide shutde... [Pg.812]
