Electrocatalysts are extremely important for accelerating the redox reaction kinetics in lithium-sulfur (Li-S) batteries. As two kinds of competitive electrocatalysts, however, transition metals (TMs) usually react with sulfur species resulting passivated surfaces, while stable rare earth oxides (REOs) exhibit low catalytic activity. Therefore, developing promising catalysts long-term activity and stability is a crucial task. Herein, TMs-REOs heterojunction catalyst consisting N-doped carbon shell containing embedded ultrafine Gd2O3 Co nanocrystals (named as Gd2O3/Co@NC) elaborately designed fabricated. Experimental theoretical results reveal that strong coupling between large number heterojunctions endows moderate adsorption satisfactory durability. Consequently, cells assembled Gd2O3/Co@NC modified separator high rate capacity (628.0 mAh g-1 at 4C), cycling (504.2 after 500 cycles 2C), utilization (4.8 cm-2 under loading 5.1 mg cm-2). This study highlights invalidation mechanism TMs Li-S batteries will inspire design advanced through REOs.

Lithium–sulfur batteries (LSBs) have become strong competitors in secondary battery systems because of their superior theoretical capacity and energy density. However, due to the serious shuttle effect soluble long-chain lithium polysulfides (LiPSs) slow solid–solid reaction kinetics, LSBs face some specific challenges, such as a short cycle life low rate performance. The introduction selenide/carbon composites derived from zeolite imidazolate frameworks (ZIFs) into separator coatings is direct effective solution aforementioned problems. Here, zinc catalyst material (ZnSe@C) was constructed employed modify commercial polypropylene (PP) separators accelerate conversion intermediates. highly polar ZnSe effectively fixes active on cathode side by transferring electrons between elements with LiPSs improves utilization sulfur. Concurrently, conductive carbon nanoskeleton generated following pyrolysis ZIF-8 ensures rapid transfer charges during catalytic reaction. prepared ZnSe@C has large surface area (250.07 m2 g–1) mesoporous ratio (78.03%), which not only enhances adsorption catalysis but also promotes penetration electrolyte transport Li+. Based this, ZnSe@C/PP cells exhibit average decay 0.051% per after 500 cycles at 1 C.
