Lithium–sulfur (Li–S) batteries have been considered as one of the effective alternative energy systems to commercial lithium-ion (LIBs) due their high theoretical density (2600 Wh kg–1), specific capacity (1675 mAh g–1), low cost, and abundant reserves sulfur. However, intrinsic challenges, such severe shuttle effect, conductivity, significant volume expansion, hinder large-scale application. In this study, a novel composite (CNT/FP-N, Se), which in situ grown with carbon nanotubes (CNTs) doped N, Se elements, has synthesized by utilizing ferric phosphate (FP) precursor. Benefitting from synergistic effects adsorption active sites CNTs catalytic N Se, effect lithium polysulfides (LPS) can be effectively inhibited, leading an enhancement Li–S when CNT/FP-N, is utilized separator modifier. The charge/discharge platforms well maintained 0.1 5 C, 617 g–1 at C acquired. Notably, initial 990.7 1 obtained, retention 711.3 after 500 cycles, corresponding loss rate only 0.056% per cycle. This work provides feasible scheme for FP application next-generation low-cost systems.

The rapid catalytic conversion toward polysulfides is considered to be an advantageous approach boost the reaction kinetics and inhibit shuttle effect in lithium-sulfur (Li─S) batteries. However, prediction of high activity Li─S catalysts has become challenging given carelessness relationship between important electronic characteristics activity. Herein, relationships D-band regulation with are described. Through combination experimental theoretical analysis, opportune upward shift center results a favorable interaction polysulfides, controlling adsorption behavior polysulfides. In addition, electron achieved by moderately moving up further reduces energy barrier through hybridization Based on this, composite catalyst Mo doped VS
