Abstract Heterostructured materials commonly consist of bifunctions due to the different ingredients. For host material in sulfur cathode lithium‐sulfur (Li‐S) batteries, chemical adsorption and catalytic activity for lithium polysulfides (LiPS) are important. This work obtains a Ni 5 P 2 ‐Ni nanoparticle (Ni ‐NiNPs) heterostructure through confined self‐reduction method followed by an situ phosphorization process using Al/Ni‐MOF as precursors. The not only has strong adsorption, but also can effectively catalyze LiPS conversion. Furthermore, synthetic route keep ‐NiNPs inside nanocomposites, which have structural stability, high conductivity, efficient adsorption/catalysis These advantages make assembled Li–S battery deliver reversible specific capacity 619.7 mAh g − 1 at 0.5 C after 200 cycles. ultraviolet‐visible technique proves effect on conversion during discharge process.

Abstract The introduction of an electrocatalyst to accelerate the kinetics lithium polysulfides (LiPSs) reduction/oxidation is beneficial enhance capacity sulfur cathode and inhibit shuttling effect LiPSs. However, current electrocatalysts mainly focus on metal‐based active sites reduce reaction barriers, there remains a great challenge in developing light‐weighted metal‐free catalysts. In this work, 1D graphitic carbon nitride nanorods (g‐C 3 N 4 ‐NRs) with carboxyl (─COOH) acylamide (─CONH 2 ) functional groups are designed as for lithium‐sulfur batteries transport Li + conversion density theory (DFT) calculations prove that existence ─COOH group realizes adsorption LiPSs accelerates , while ─CONH energy barrier S 8 S. addition, situ UV–vis nucleation/dissociation experiments also verify g‐C ‐NRs achieve rapid transformation under synergistic action groups. Consequently, based ‐NRs‐PP separator at specific 700.3 mAh g −1 after 70 cycles 0.2 C, 0 °C. This work provides new strategy breaking through bottleneck catalysts high‐performance batteries.
