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.

Abstract The electrochemical oxygen evolution reaction (OER) can be combined with various reactions to fabricate energy conversion and storage devices while the slow kinetics poor mass transfer capability at high current densities are key constraints its large‐scale application. Therefore, this review primarily focuses on design optimization of structures TM‐metal‐based OER catalysts. Nanostructuring, porous design, creation hierarchical architectures have been applied during catalyst synthesis enhance surface area accessibility, thereby improving catalytic efficiency. Strategies including doping, substrate invitation, soft/hard templating utilized accelerate as well ion/electron conduction efficiency for overall improvement performance These developments underline critical role advanced material in achieving high‐performance catalysts highlight potential TM‐based materials cost‐effective scalable applications.
