This interest stems from their simultaneous roles as sulfur hosts and electrocatalysts, which provide enhancements to the performance of sulfur cathode composites. Nonetheless, their incorporation into the active material blend results in compromised energy density, particularly when their gravimetric proportion is substantial (≥10 wt.%, in the sulfur-based cathode). In this study, a manganese (Mn)-containing HEO (Sconfig ≥ 1.5R) was synthesized and subsequently coated onto a commercial Celgard separator at a low areal loading (~0.23 mg cm−2) with the aim of decreasing HEO content in the cathode composite material while still boosting lithium polysulfide (LPS) conversion kinetics. Li–S batteries incorporating this modified separator-high entropy oxide (MS-HEO) demonstrate exceptional electrochemical performance, achieving a high initial discharge capacity of ~1642 mAh g−1 at 0.1 C and a remarkably low-capacity fade rate of 0.055% per cycle over 450 cycles at 1 C. Remarkably, the MS-HEO batteries exhibited commendable electrochemical performance at high sulfur loading (~7 mg cm−2), delivering an initial discharge capacity of ~819 mAh g−1 during the first discharge and maintaining stable cycling up to 30 cycles at 0.1 C thereafter. Collectively, this work underscores the significance of precise adjustment of HEO compositions through low-temperature MOF calcination strategies and demonstrates their potential to enhance the electrochemical performance of Li–S batteries under the high-sulfur loading conditions necessary for future commercial applications.","PeriodicalId":11554,"journal":{"name":"Energy & Environmental Materials","volume":"8 6","pages":""},"PeriodicalIF":14.1,"publicationDate":"2025-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eem2.70058","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145272778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recombination velocities sGB were determined at a large number of GBs by evaluating profiles extracted from cathodoluminescence intensity distributions across GBs in these polycrystalline layers. In both Li-ACZTSSe and CZTS absorber layers, the sGB values exhibited wide ranges over several orders of magnitude with a median values of 680 and 1100 cm s−1 for the Li-ACZTSSe and CZTS absorbers. A model that provides a comprehensive explanation for this finding is presented and discussed in detail. Correspondingly, wide ranges for sGB can be explained by different positive or negative excess charge densities present at different GBs, leading to different downward or upward band bending on the order of several ±10 meV, provided that the net-doping density of the absorber layers is sufficiently large. As a result of the evaluation of the sGB, input parameters for multidimensional device simulations are obtained. It is revealed that the grain boundary lifetime closely matches the overall effective lifetime, indicating that grain boundary recombination is a key factor limiting the effective carrier lifetime of both Li-ACZTSSe and CZTS absorbers. The estimated VOC losses due to GBs reach up to 126 mV for Li-ACZTSSe and 88 mV for CZTS. This work highlights that reducing grain boundary recombination via improved passivation and increasing grain size is an effective strategy for achieving further efficiency improvements.","PeriodicalId":11554,"journal":{"name":"Energy & Environmental Materials","volume":"8 6","pages":""},"PeriodicalIF":14.1,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eem2.70048","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145272911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, controllable approaches for creating heterostructures based on vertically standing transition metal dichalcogenide (TMD) nanosheets remain insufficient despite their potential for efficient hydrogen production. In this paper, we present efficient photocatalysts featuring heterojunctions composed of vertically grown TMD (MoS2 and WS2) nanosheets. These structures (WS2, MoS2, and MoS2/WS2 heterostructure) were fabricated using a controllable metal–organic chemical vapor deposition method, which expanded the surface area and facilitated effective photocatalytic hydrogen evolution. The vertical MoS2/WS2 heterostructures demonstrated significantly enhanced hydrogen generation, driven by the synergistic effects of improved light absorption, a large specific surface area, and appropriately arranged staggered heterojunctions. Furthermore, the photocatalytic activity was considerably influenced by the size and density of the vertical nanosheets. Consequently, the nanosheet size-tailored MoS2/WS2 heterostructure achieved a photocatalytic hydrogen generation rate (454.2 μmol h−1 cm−2), which is 2.02 times and 2.19 times higher than that of WS2 (225.6 μmol h−1 cm−2) and MoS2 (207.2 μmol h−1 cm−2). Hence, the proposed strategy can be used to design staggered heterojunctions with edge-rich nanosheets for photocatalytic applications.","PeriodicalId":11554,"journal":{"name":"Energy & Environmental Materials","volume":"8 5","pages":""},"PeriodicalIF":14.1,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eem2.70055","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144773469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their practical application is hindered by the poor electronic conductivity of iodine cathodes and the severe shuttling effect of intermediate polyiodides. Here, we report a novel micropores carbon framework (MCF) synthesized from waste coffee grounds via a facile carbonization-activation process. The resultant MCF features an ultrahigh specific surface area and a high density of micropores, which not only physically confine iodine species to minimize iodine loss but also enhance the electronic conductivity of the composite cathode. Furthermore, biomass-derived heteroatom dopings (nitrogen functionalities) facilitate effective chemical anchoring of polyiodide intermediates, thereby mitigating the shuttle effect. UV–visible spectroscopy and electrochemical kinetic analyses further confirm the rapid transformation and inhibition mechanism of iodine species by MCF. Consequently, the MCF/I2 cathode delivers superior specific capacities of 238.3 mA h g−1 at 0.2 A g−1 and maintains outstanding cycling performance with a capacity retention of 85.2% after 1200 cycles at 1.0 A g−1.

Herein, a crystal and electron synergistically regulation engineering strategy is proposed for the suppression of the Jahn–Teller effect and the improvement of ammonium ion storage dynamics in F doped MnO2 (MnOF). The induced action of F ions transforms the MnO2 structure from the original cubic [MnO6] octahedron into an asymmetric [Mn(OF)6] octahedron with electron redistribution, and generates a localized charge imbalance along the O–Mn–F pathway, which promotes electron transfer from Mn to F direction, accelerates electron transfer, and reduces the energy barrier of ammonium ion diffusion. As a result, the prepared MnOF exhibited a maximum salt adsorption capacity of 144.3 mg g−1 and an exceptionally high salt adsorption rate of 18.25 mg g−1 min−1, along with outstanding cycling stability.

This study demonstrates that a LiBF4-derived F-rich coating on LiCoO2, applied by immersing LiCoO2 particles in a LiBF4 solution followed by annealing, can significantly enhance performance in Li6PS5Cl-based solid-state batteries.
