Lithium‐sulfur batteries (LSBs) possess exceptionally high theoretical energy density and specific capacity, making them promising candidates for next‐generation energy storage systems. However, the sluggish adsorption and catalytic conversion kinetics of lithium polysulfides severely hinder their practical application. In this work, a functional separator modified with antiperovskite nitride (IZNC) was developed. The precise incorporation of In at the antiperovskite. A‐site regulation effectively modulated the spin state of Co active sites, inducing a low‐spin to high‐spin transition of Co ions and thereby enhancing their affinity for polysulfides. Furthermore, the antiperovskite transformed the conventional two‐dimensional Li ₂ S deposition behavior into a mixed 2D/3D growth mode, Such altered deposition morphology facilitates Li ₂ S nucleation‑growth kinetics and enhances the overall reaction reversibility of the sulfur cathode. Consequently, the assembled cell exhibited outstanding cycling stability, with an average capacity decay of only 0.06% per cycle over 600 cycles at 1 C. Moreover, even at a high sulfur loading of 4.3 mg cm ⁻² , an impressive areal capacity of 6.1 mAh cm ⁻² was achieved. This work provides valuable insights into the rational design of functional separators for high‐performance LSBs.

Cerium oxide (CeO2) nanoparticles and carbon nanofibers (CNF) are promising fillers for prolonging the service life of epoxy resin (EP) coatings, valued for their corrosion inhibition and mechanical strength. However, their direct application in EP coatings often results in inadequate anti-corrosion performance due to weak interfacial interactions and agglomeration. Here, CeO2 nanoparticles were in-situ grown on the CNF surface (CeO2/CNF) by controlling the amount of cerium salt to polyacrylonitrile, using electrospinning, oxidation, and carbonization processes. The rough CeO2/CNF surface provides a larger contact area with the epoxy (EP) matrix, promoting strong mechanical interlocking, therefore it can reduce interfacial porosity and improve the barrier properties of the composite coating. The optimized coating of CeO2-3/CNF/EP exhibited an excellent anticorrosion performance. The electrochemical impedance spectroscopy (EIS) results showed that the |Z|0.01 Hz value of CeO2-3/CNF/EP coating decreased from 3.65×108 Ω·cm2 to 1.26×108 Ω·cm2 after immersion in a 3.5 wt.% NaCl solution for 56 days, remaining two orders of magnitude higher than that of pure EP coating and superior to the other coatings.The outstanding corrosion resistance is attributed to the synergistic effect of the mechanical interlocking provided by rough CNF and the corrosion inhibition of a passive film resulted by CeO2 nanoparticles.

The efficiency of oxygen reduction and evolution reactions is fundamentally constrained by macroscopic mass transport bottlenecks at the triple‐phase interface and the quantum‐mechanical restriction of spin‐forbidden transitions. This review presents a multilevel framework to overcome these barriers. At the macroscopic solid–liquid–gas boundary, bio‐inspired and asymmetric wettability architectures enable the decoupling of gas and ion transport channels, thereby alleviating diffusion‐limited current scaling. At the atomic level, defect engineering, size control, heteroatom doping and synergistic heterointerface construction regulate local electronic structure and oxygen intermediate adsorption. Beyond intrinsic material design, external physical fields act as dynamic levers, ranging from magnetohydrodynamic enhancement of bubble detachment to magnetic exchange interactions for spin alignment. We further highlight chiral spintronics, where the chiral‐induced spin selectivity effect provides an intrinsic field‐free route for spin filtering. By promoting parallel spin alignment of radical intermediates, intrinsic chirality facilitates triplet oxygen formation. Finally, we integrate these multilevel strategies to outline a path toward next‐generation oxygen electrocatalysts, while identifying critical challenges in stability, spin‐sensitive operando characterization, standardized evaluation, and practical scalability.
