Atomic insights into the electrocatalytic properties of LaBO3 perovskite oxides for lithium–sulfur battery performance

(B = Cr, Mn, Fe, and Co) effectively activates the O and B sites by enabling O to capture electrons initially transferred from Li to S. This process promotes the formation of Li-O and B-S bonds, thereby mitigating the shuttle effect, weakening the Li-S bonds, and enhancing the redox kinetics of LSBs. These findings offer valuable insights for the future design of more efficient perovskite-based electrocatalysts.
