The inferior shuttle effect of intermediate lithium polysulfides and the sluggish kinetics of sulfur redox reaction are two serious puzzles for the application of lithium–sulfur batteries. Herein, energy band alignment is combined with oxygen vacancies engineering to obtain TiO2 anatase/rutile homojunction (A/R‐TiO2) with effective immobilization and high‐efficiency catalytic conversion of polysulfides...
The shuttling effect and sluggish reaction kinetics are the main bottlenecks for the commercial viability of lithium–sulfur (Li–S) batteries. Metal‐nitrogen‐carbon single atom catalysts have attracted much attention to overcoming these obstacles due to their novel electrocatalytic activity. Herein, a novel cooperative catalytic interface with dual active sites (oversaturated Fe‐N5 and polar Fe2O3...
