Introducing carbon interlayers is an effective strategy especially in increasing the discharge capacity in coin cells. Nevertheless, the underlying capacity enhancement mechanism afforded by carbon interlayers remains unclear, hindering their further optimization and application in practical devices. Herein, different geometric configurations of carbon interlayers are designed to unveil the actual capacity enhancement mechanism. Through correlating the dead zone area of coin cells with the capacity enhancement afforded by carbon interlayers, re-utilization of the lithium polysulfides diffused into the coin cell dead zones is identified as the primary cause while carbon interlayers are less effective in nearly dead-zone-free pouch cells. Therefore, carbon interlayers are more suitable as a platform for convenient and rapid activity evaluation of electrocatalysts tailored for Li–S batteries. This work re-recognizes the working mechanism and practical applicability of carbon interlayers and guides rational employment of carbon interlayers in developing advanced Li–S batteries.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"209 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143463227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, it is shown that O─O dimerization triggers transition-metal migration in an oxygen-redox positive electrode upon charging. First-principles calculations are performed to reveal the thermodynamic and kinetic energy landscapes of the full structural evolution of a typical lithium-rich oxide, i.e., Li1.2Ni0.13Co0.13Mn0.54O2. The oxygen oxidation process can be divided into three sequential steps: i) generation of persistent oxidized oxide ion O−; ii) peroxide formation; and iii) transition-metal migration.

However, their practical applications are hindered by poor cycling stability resulting from the instable structure during charge/discharge and inherently low electronic conductivity. To tackle these issues, herein, this study presents the design and synthesis of spongy silicon-doped MoS2 induced by the long-chain molecules in mesopores. The material consists of few-layered nanofragments with high porosity, resulting in abundant edge sites and sulfur vacancies. These structural features can promote Li+ transport and accommodate electrode volume changes during charge/discharge. Electrochemical and theoretical analyses reveal that silicon doping enhances the electronic conductivity of MoS2, while the nanostructure design enables reversible Li⁺ diffusion along the edges, distinct from Li+ storage in the interlayers of conventional MoS2 anodes. Notably, the material delivers a high reversible capacity of 767.9 mAh g−1 at 0.1 A g−1 and exhibits remarkable rate capability. Moreover, it demonstrates superior cycling stability with over 83% capacity retention even after 1000 cycles at 1.0 A g−1, outperforming most existing MoS2-based anode materials.

Aqueous zinc-ion batteries (ZIBs) are becoming increasingly popular due to their safety, eco-friendliness, and cost-effectiveness. However, challenges remain in achieving realistic storage time per charge, long cycling life, and high energy storage capacity in practical conditions. Despite advancements in cathode materials, issues such as dissolution and side reactions limit their performance. Optimizing cathode architecture and electrolyte composition is essential to address these challenges. Tailored electrolyte formulations can stabilize electrode-electrolyte interface (EEI and enhance cycling stability. This perspective reviews cathodes from the past decades and compares their performance under different current densities. Emphasizing low current density performance and extended cycling stability is crucial for the widespread adoption of ZIBs in grid-scale applications. By focusing on these aspects, this perspective aims to bridge the gap between research and practical applications, offering insights into optimizing material structure and selecting matching electrolytes for grid-scale energy storage. This work guides future developments in ZIB technology, facilitating their transition from the lab to real-world deployment.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"25 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143463225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the carbazole core of [4-(3,6-dimethyl-9H-carbazol-9-yl)butyl]phosphonic acid (Me-4PACz) is insufficiently effective for passivating defects at the “bottom” of perovskite films, and the weak anchoring ability of phosphate groups toward the NiOx substrate appears to promote the formation of dimers, trimers, and higher-order oligomers, resulting in molecular accumulation. Herein, a novel technique is proposed to combine Me-4PACz with different thiol molecules to modify the buried interface of PSCs. Molecular dynamics simulations and infrared scattering-type scanning near-field optical microscopy (IR s-SNOM) results show that co-depositing Me-4PACz with thiol molecules forms hybrid SAMs that densely and uniformly cover the NiOx surface. The island-like structure of the hybrid SAMs serves as a template for forming the perovskite bulk heterojunction composed of interpenetrating networks of MA-rich and FA-rich domains, enabling efficient charge generation and suppressed bimolecular recombination. Particularly, (3-mercaptopropyl) trimethoxysilane (MPTMS) effectively prevents Me-4PACz aggregation by forming a multi-dentate anchor on the NiOx surface through hydrolytic condensation of ─OCH3 groups, while its ─SH groups passivate uncoordinated Pb2+ at the perovskite/HTL interface. Consequently, the resulting hybrid SAMs-modified PSC achieve a champion photoelectric conversion efficiency (PCE) of 25.4% and demonstrated better operational stability.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"67 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143463228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inspiringly, the AEMWE performance on Ru-S-NiFe LDH is also superior to the NiFe LDH. In-depth mechanism investigations reveal that Ru single atoms not only act as the highly active sites, but also facilitate the conductivity of NiFe LDH. Meanwhile, S anions accelerate the electrochemical reconstruction of NiFe LDH to OER-active NiFeOOH and alleviate the over-oxidation issue on Ru active sites. Benefiting from these, Ru-S-NiFe LDH shows significantly enhanced OER activity and stability. Theoretical calculations further validate the decreased OER free energy difference brought about by the Ru single atoms and S anions dual-doping.

Regulating electric double layer (EDL) structure is an effective strategy to address these issues. Herein, a perovskite dielectric ZnTiO3 (ZTO) layer is designed on Zn anode to construct the autoregulative EDL for achieving fast charging capability. The ZTO layer can spontaneously generate the surface charge with external voltage to regulate the EDL structure, which results in an increased/decreased EDL capacitance under Zn plating/stripping potential respectively, leading to promoted Zn2+ solvation/de‐solvation for rapid reaction kinetics. Meanwhile, the H2O‐insufficient environment created by self‐regulated EDL and uniform electric field can prevent side reaction and dendrite growth during deposition process. Attributed to its EDL feature, ZTO@Zn exhibits an excellent cycle stability over 2850 h at 1 mA cm−2 in symmetrical cells. Even at high current density of 50 mA cm−2, it still exhibits a stable cycle for 230 h.
