So far, the understanding of intricate relationship between structure and performance in hard carbon remains piecemeal, with research efforts scattered across various aspects, thereby numerous controversies have arisen in this field. Here, we provide new insights into structure-performance relationship in hard carbon by coupling key structural parameters based on integrating theoretical computations and experimental data. Density functional theory calculations show that interlayer spacing determines diffusion behavior of sodium ions in hard carbon, while appropriate defect and curvature secure high-quality intercalation capacity. Inspired by these theoretical results, we successfully produce high-performance hard carbon with optimal microstructures through in-situ molecular reconfiguration of biomass via thermodynamically-driven approach, which is demonstrated as an effective strategy to rationally regulate the microstructure of hard carbon by comprehensive physical characterizations from macroscopic to atomic level. More importantly, cylindrical batteries (18650 and 33140 types) fabricated from industrial-scale hard carbon exhibit fabulous sodium storage behaviors with excellent wide-range temperature performance (-40-100 oC), demonstrating great potential for achieving practical sodium-ion batteries with high energy density and durability in the future.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"33 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872286","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}

Recent research shows that the freezing point can be effectively lowered by using either concentrated salt or organic-rich electrolytes. However, these strategies result in either low oxidation stability or sluggish mass transport at low temperatures. Here, we report a multi-tentacle electrolyte (MTE) strategy that enables stable, fast and deep running of AZBs at −40 °C. MTE leverages the abundant hydrogen-bonding sites of multi-tentacle salts and organics. Adding small amounts of multi-tentacle moieties not only effectively confines water molecules’ movement and prevents their icing even at −60 °C, but also maintains low viscosity and high ionic conductivity of the electrolyte at low temperatures. At −40 °C, Zn metal anodes could stably cycle for more than 1100 hours at a high current density of 2 mA cm−2 and a high capacity of 2 mAh cm−2; high-capacity AZBs (3.4 mAh cm−2) sustain 1000 stable cycling with 99.99% retention per cycle in MTE. MTE strategy is also versatile to high-voltage LiMn2O4 cathodes, which further enhances the energy density of AZBs to 154.4 Wh kgLMO−1 at −40 °C.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"1 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872288","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}

The intrinsic thermodynamic instability of Zn metal anodes in mildly acidic Zn-ion batteries can trigger spontaneous interfacial corrosion, which leads to hydrogen evolution, the formation of byproducts, and the irreversible loss of active species during both storage and operation. Here, we delve into the intricate corrosion processes of the Zn metal anode in mildly acidic electrolytes. With the help of operando electrochemical liquid cell transmission electron microscopy, the self-dissolution of Zn is observed, and the capacity loss due to such corrosion behaviour during the cell rest period is quantified. This dissolution of Zn is found to be closely related to the initial pH value of the electrolyte and can be mitigated by pH adjustment through the slight addition of a pH buffer additive. The self-dissolution of Zn, which causes an increase in the local pH, is a prelude to the formation of corrosion byproducts that continues throughout the entire storage and cycling period. These corrosion issues are exacerbated by the presence of excess Zn metal in the system, suggesting that the feasibility of using excess Zn metal in Zn-ion batteries should be carefully evaluated. These findings further emphasise the importance of considering electrolyte pH in future electrolyte modification research, as well as its potential impacts on the stability of both the anode and cathode, and the shelf life of the entire battery.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"1 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872290","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}

Although flat two-dimensional (2D) evaporators exceeding the solar limit implies a non-thermal process, tall three-dimensional (3D) solar evaporators can exceed it by absorbing additional environmental heat into its cold sidewalls. Through modeling, we explain the physics and identify the critical heights in which a fin transitions from 2D to 3D evaporation and exceeds the solar-thermal limit. Our analyses illustrate that environmental heat absorption in 3D evaporators is determined by the ambient relative humidity and the airflow velocity. The model is then coarse-grained into a large-scale fin array device on the meters scale to analyze their scalability. We identify that these devices are unlikely to scale favorably in closed environment settings such as solar stills. Our modeling clearly illustrates the benefits and limitations of 3D evaporating arrays and pinpoints design choices in previous works that hinder the device’s overall performance. This work illustrates the importance in distinguishing 2D from 3D evaporation for mechanisms underlying interfacial evaporation exceeding the solar-thermal limit.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"31 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866905","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}

The study compares three different processes (plasma-assisted dry reforming (CO<small><sub>2</sub></small>/CH<small><sub>4</sub></small>), oxi-CO<small><sub>2</sub></small> reforming (CO<small><sub>2</sub></small>/CH<small><sub>4</sub></small>/O<small><sub>2</sub></small>) and bi-reforming (CO<small><sub>2</sub></small>/CH<small><sub>4</sub></small>/H<small><sub>2</sub></small>O)), as well as with current state-of-the-art steam reforming technology. Advancements in cost reduction and environmental performance are highlighted. While comparative studies on different plasma processing concepts have been published, their number is not large; meaning this study is bespoke in this aspect. Our study is also bespoken in extensive consideration of industrial gas separation, to provide a holistic view on sustainability with industrial viewpoint. Three different production design scenarios were considered in the analysis: DRM (scenario 1), oxy-CO<small><sub>2</sub></small> reforming of CH<small><sub>4</sub></small> (OCRM) (scenario 2), and bi-reforming of CH<small><sub>4</sub></small> (BRM) (scenario 3). This evaluation was carried out through a techno-economic analysis and a cradle-to-gate life cycle assessment (LCA). Among the scenarios analysed, OCRM demonstrates the most favourable economic performance, leading to a unitary cost of production of 549 $/tonne syngas, followed by DRM and BRM. However, when operating at large scale, the syngas production cost of BRM could compete with the benchmark if 20% reduction in plasma power consumption can be achieved, so in the near future, plasma-based BRM could be competitive against other more mature electric-powered technologies. When assessing environmental performance across 10 environmental categories of LCA metrics, OCRM is again preferred, followed by DRM and BRM. Key impact categories identified include freshwater eutrophication potential and energy consumption, which are significant contributors to environmental impacts. A study on the transition of energy sources indicates a substantial decrease in global environmental impact in the range of 50% when shifting from current electricity generation methods to wind energy sources. Comparative benchmarking reveals that the technologies evaluated in all three plasma scenarios perform better in environmental metrics across 7 over 9 categories assessed, when compared with current state-of-the-art steam reforming technologies. A material circularity indicator around 0.7 is obtained in all scenarios with slight differences, reflecting a medium-high level of circularity.
