Mechanistic modeling of polysulfide shuttle and capacity loss in lithium–sulfur batteries [PDF]

open access: yesJournal of Power Sources, 2014
Abstract Lithium–sulfur (Li/S) cells are promising candidates for a next generation of safe and cost-effective high energy density batteries for mobile and stationary applications. At present, most Li/S cells still suffer from relatively poor cyclability, capacity loss under moderate current densities and self-discharge.

Tunnel Structure Enhanced Polysulfide Conversion for Inhibiting “Shuttle Effect” in Lithium-Sulfur Battery

open access: yesNanomaterials, 2022
The Lithium sulfur (Li-S) battery has a great potential to replace lithium-ion batteries due to its high-energy density. However, the “shuttle effect” of polysulfide intermediates (Li2S8, Li2S6, Li2S4, etc.) from the cathode can lead to rapid capacity ...

Approaches to Combat the Polysulfide Shuttle Phenomenon in Li–S Battery Technology

open access: yesBatteries, 2022
Lithium–sulfur battery (LSB) technology has tremendous prospects to substitute lithium-ion battery (LIB) technology due to its high energy density. However, the escaping of polysulfide intermediates (produced during the redox reaction process) from the cathode structure is the primary reason for rapid capacity fading.

Selective catalysis remedies polysulfide shuttling in lithium-sulfur batteries [PDF]

open access: yesAdvanced Materials, 2020
Abstract The shuttling of soluble lithium polysulfides between the electrodes leads to serious capacity fading and excess use of electrolyte, which severely bottlenecks practical use of Li-S batteries. Here selective catalysis is proposed as a fundamental remedy for the consecutive solid-liquid-solid sulfur redox reactions. The proof-of-concept

A polysulfide radical anions scavenging binder achieves long‐life lithium–sulfur batteries

open access: yesBattery Energy, 2022
Fast capacity decay caused by the polysulfide shuttle is the primary cause to impede the practical application of lithium–sulfur (Li–S) batteries. The polysulfide shuttle involves the evolution of polysulfide dianions (Li2Sx, x = 3–8) and radical anions (
