Designing and mapping cascade catalysis pathway for balanced polysulfide conversion in Li-S batteries [PDF]
Nature CommunicationsLithium–sulfur batteries are fundamentally constrained by the sluggish 16-electron sulfur reduction reaction. Electrocatalytic sulfur reduction reaction is inherently complex, involving multiple lithium polysulfide intermediates (Li2Sn, n = 2–8), each ...

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