Single-atom catalysts (SACs) pave new possibilities to improve the utilization efficiency of sulfur electrodes arising from polysulfide shuttle effects and sluggish kinetics due their excellent applicability in atomic-scale reaction mechanisms structure-activity relationships. Herein, nitrogen (N)-anchored SACs on highly ordered N-doped carbon nanotube arrays are reported as host for fast redox conversion lithium-sulfur (Li-S) batteries. The cube structure aligned nanotubes can promote rapid...
The sluggish sulfur redox kinetics and shuttle effect of lithium polysulfides (LiPSs) are recognized as the main obstacles to practical applications lithium-sulfur (Li-S) batteries. Accelerated conversion by catalysis can mitigate these issues, leading enhanced Li-S performance. However, a catalyst with single active site cannot simultaneously accelerate multiple LiPSs conversion. Herein, we developed novel dual-defect (missing linker missing cluster defects) metal-organic framework (MOF)...
Abstract Lithium–sulfur (Li–S) batteries promise high theoretical energy density and cost‐effectiveness but grapple with challenges like the polysulfide shuttle effect sluggish kinetics. Metal–organic framework (MOF) catalysts emerge as a leading solution, despite limited conductivity steric hindrance.
