Functional protective coatings on lithium metal surfaces offer a viable solution to these challenges. Herein, an innovative adaptive protective layer for lithium metal anodes based on a thiourea H-bonded supramolecular polymer is developed for the first time. With dense thiourea H-bonding, the lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) incorporated poly(ether-thiourea) protective layer shows strong adhesion to the lithium metal surface and good adaptive properties. The unique viscoelastic and flow characteristics of the poly(ether-thiourea) coating facilitate uniform Li⁺ flux, effectively suppressing dendrite formation at the solid electrolyte interface. Furthermore, this innovative polymer integrates in situ generated compounds, such as Li₃N and Li₂O, significantly enhancing interfacial stability.

Generally, the failure mechanism of conversion-alloy anodes is ascribed to volume expansion or the shuttle effect, which, however, fails to adequately explain their characteristic electrochemical behavior: an initial rapid drop and then a gradual decline in capacity. Herein, by combining electrochemical characterizations with multi-scale microscopies, spectroscopy, and theoretical calculations, we systematically analyze the failure mechanism of Bi₂Te₃, a typical conversion-alloy anode. The failure processes and mechanisms are identified into two stages: (1) the rapid capacity fading dominated by the shuttle effect in the first several cycles and (2) the gradual material deactivation and capacity decline due to solid-electrolyte interphase accumulation in the following cycles. Furthermore, in response to these failure mechanisms, an elaborate design of Bi₂Te₃-based electrode featuring ultrafine nanoparticles and carbon encapsulation is presented, which exhibits prominent capability in avoiding the above negative effects and substantially enhancing cycling stability. This study reveals the failure mechanism of conversion-alloy anode throughout its entire life cycle, and the gained insight may lead to targeted optimization strategies for stable high-capacity electrodes.</p>","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"8 2","pages":""},"PeriodicalIF":24.2,"publicationDate":"2026-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.70129","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147570001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method is evaluated using experimental data and various exchange-correlation functionals and materials for C- and O-containing species. Our main conclusion is that no functional is simultaneously accurate for adsorbates and molecules, as adsorbed-phase errors are visibly different from gas-phase errors. Importantly, total, gas-phase, and adsorbed-phase errors are correlated, revealing intrinsic DFT limitations and enabling the elaboration of swift correction routines.

Herein, we develop a facile solvent evaporation strategy to synthesize ultrathin Al₂O₃-coated biomass-derived HC (GSC-Al₂O₃-3%). The conformal Al₂O₃ layer passivates defects and micropores, suppresses side reactions, and promotes the formation of a robust organic–inorganic hybrid solid electrolyte interphase. Comprehensive characterizations, including in situ X-ray diffraction, ex situ Raman spectra, X-ray photoelectron spectroscopy, time of flight secondary ion mass spectrometry, solid-state ²⁷Al nuclear magnetic resonance, and atomic force microscope modulus mapping, demonstrate that Al₂O₃ actively participates in SEI reconstruction, enhancing the chemical and mechanical stability. Electrochemical tests reveal that the optimized GSC-Al₂O₃-3% anode delivers 91% capacity retention after 1000 cycles at 1.0 A g⁻¹, and possesses excellent wide-temperature tolerance (149.3 mAh g⁻¹ at −30°C and 286.8 mAh g⁻¹ at 60°C). Mechanistic studies confirm a synergistic Na⁺ storage process involving “adsorption–intercalation–pore filling,” while density functional theory calculations and electrostatic potential mapping reveal that Al₂O₃ coating regulates interfacial charge distribution and reduces Na⁺ migration barriers. A full cell paired with a NaNi_0.5Fe_0.5MnO₄ cathode exhibits a high initial capacity of 395.7 mAh g⁻¹ and outstanding cycling stability (200 cycles).

This study demonstrates for the first time that washing hydrochars in solvents of different polarity before activation is a simple yet powerful strategy to tailor pore size distribution. Hydrochar is produced from spent coffee grounds via hydrothermal carbonization, followed by washing in various solvents and activation in KOH. This results in carbons with a very large surface area (∼2700 m²/g), and washing is demonstrated to significantly increase product yield. Furthermore, washing in non-polar or mixed-polarity solvents removes long-chain carboxylic acids and esters from the hydrochar, promoting the development of narrow micropores while suppressing mesopore formation. To illustrate the impact of this structural control of porous carbons, post-combustion CO₂ capture is investigated as a case study. Narrower pore size distribution enhances CO₂ uptake, significantly improving capacity from 2.8 mmol/g for unwashed samples to 3.8 mmol/g for acetone-washed samples. Interestingly, moderate pore size (9–12 Å) is shown to be optimal for CO₂:N₂ selectivity, while smaller pores result in lower selectivity due to stronger interactions between N₂ and the pore walls. These findings highlight the potential role of solvent washing in directing pore architecture of hydrochars for adsorption-based carbon capture technologies and beyond.</p>","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"8 2","pages":""},"PeriodicalIF":24.2,"publicationDate":"2026-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.70141","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147564312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although traditional magnetic absorbers, such as ferrites and metal powders, show excellent magnetic loss performance at room temperature, they have significant limitations in harsh environments due to their high density, low Curie temperature, and susceptibility to oxidation. In contrast, carbon-containing materials have emerged as promising candidates for high-temperature EWA applications, owing to their high melting point, low density, tunable dielectric loss mechanisms, and superior thermal stability. Unlike magnetic materials, carbon-based systems primarily dissipate electromagnetic energy through conductance loss, dipole polarization, and interfacial polarization, thereby avoiding performance degradation at elevated temperatures. However, several critical challenges remain, including insufficient oxidation resistance, mechanical reliability issues, and the need for stable impedance matching. To address these limitations, recent strategies such as defect engineering, heterointerface construction, and metamaterial design have been proposed to enhance thermal stability and functional performance. This review provides a systematic summary of recent advances in carbon-containing absorbers, with a focus on dielectric loss mechanisms, optimization strategies, and multiscale structural design principles. By elucidating the structure–property relationships of carbon materials, carbide ceramics, and novel carbon hybrids, this study aims to offer theoretical and technical guidance for the development of advanced high-temperature electromagnetic wave absorbers, thereby promoting their practical applications in aerospace and telecommunications.</p>","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"8 2","pages":""},"PeriodicalIF":24.2,"publicationDate":"2026-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.70118","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147565675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
