Herein, LIB-grade graphite is produced using a less energy-intensive catalytic graphitization process. This work explores the catalytic graphite (CTG) growth mechanism, the impact of graphitization conditions on the degree of graphitization, aspects of developing high-rate graphite anodes, upscaling strategies, and techno-economic prospects. Operando thermal X-ray diffractograms reveal that the CTG forms through carbon dissoluton in nickel and its subsequent segregation as graphite and nickel. CTG synthesized between 1100 and 1500 °C shows porous flaky morphology, with higher temperatures favoring superior graphitization and carbon purity. The growth of graphitic domains governs the electrochemical performance of CTG. CTG 1100 shows hard carbon-like Li+ ion storage, while CTG 1300 and CTG 1500 form graphite intercalation compounds owing to the larger graphitic crystallites. Pitch-derived soft carbon coating onto CTG 1500 enhances its high-rate capability compared to commercial graphite due to its intrinsic porosity. Improved electrochemical performance establishes CTG as a better alternative to NG and SG, and detailed techno-economic analysis affirms its scalability prospects.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"53 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144066329","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}

Herein, a novel 1D perovskite based on 1,3-thiazole-2-carboximidamide (TZC) cation is introduced, which exhibits robust chemical interactions with PbI2 and 3D perovskite, enabling the fabrication of high-quality mixed-dimensional perovskite films identified by both HR-TEM and GIWAXS analyses. Benefiting from the lower formation energy barrier of 1D perovskites, they can preferentially form and act as crystal seeds to regulate perovskite crystallization kinetics with optimized morphology and improved crystallinity. In addition to effectively passivating surface defects and suppressing nonradiative recombination, TZC-enabled 1D perovskites exhibit pronounced n-type doping characteristics, leading to an elevated Fermi level (from −4.63 to −4.44 eV) and facilitating improved charge carrier extraction and transport in p-i-n perovskite devices. As a result, this strategy not only significantly enhances the power conversion efficiency (PCE) of the widely studied 1.55 eV bandgap perovskite but also boosts the PCE of 1.68 and 1.85 eV wide-bandgap perovskite devices, achieving outstanding PCEs of 22.52% and 18.65%, respectively.

Herein, a design strategy for the preparation of N-doped RuO₂ using TiN nanoparticles as the nitrogen source is presented. The in- situ characterization and theoretical calculation reveal the optimized oxygen evolution reaction (OER) mechanism on the resulting N-RuO2/TiN catalyst. The incorporation of low-electronegativity N and the formation of interfacial Ru−O−Ti bridge structure lead to the redistribution of electron density on adjacent Ru sites, weakening the Ru–O covalency and inhibiting the reactivity of lattice oxygen during electrocatalytic OER. Meanwhile, the altered electronic structures also optimize the adsorption energy of intermediates, consequently facilitating the formation of the pivotal intermediate *OOH and enhancing the electrocatalytic activity. The N-RuO2/TiN electrocatalyst displays a extremely low OER overpotential of 159 mV at 10 mA cm−2 in 0.5 m H2SO4. Particularly, the water electrolysis single cell with N-RuO2/TiN as anode electrocatalyst conveys an extremely low voltage of 1.78 V at 3A cm−2 and degradation rate of 26 µV h−1 during a 1100 h operation at 1 A cm−2.

However, LMFPs are veiled by their asymmetric charge-discharge voltage profiles that arise from complex phase transitions. In this study, first-principles calculations are employed to systematically investigate the phase transition mechanisms and electronic structure evolutions in LiFePO4 and LiMnPO4, with a focus on elucidating the behavior of Li1–xMnyFe1−yPO4 for next-generation lithium-ion batteries. Detailed phase diagrams across the full lithiation range, combined with partial density of states analysis, reveal that the dual voltage plateaus arise from the distinct redox processes of Fe2+/Fe3+ and Mn2+/Mn3+. Notably, the thermodynamic equilibrium reaction pathway of LMFP follows a sequence of biphasic, monophasic, and biphasic transitions. In contrast, the intrinsic insulating characteristics of iron phosphate trigger a non-equilibrium reaction during charging. This non-equilibrium behavior, marked by phase segregation and limited electron mobility due to Mott-insulator characteristics, leads to a stepwise (stair-like) voltage profile during charging, whereas the discharging process follows an equilibrium pathway with a smoother voltage response. These insights into the interplay between thermodynamics, electronic structure, and insulating properties provide a theoretical foundation for understanding LMFP cathodes.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"23 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144000669","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, it is still a great bottleneck that the AWE technology cannot meet the fluctuating renewable energies, due to the instability and poor resistant counter-current property of electrocatalysts in AWE. Herein, a high-stable and robust WMo-CoP@NM electrocatalyst is constructed by modulating the electronic structure of CoP catalysts. The catalyst not only exhibits excellent hydrogen evolution reaction (HER) performance at ampere-level current densities, but also presents outstanding resistant counter-current property and adaptability for multi-cycle start-stop tests in AWE, which offers an opportunity to use fluctuating renewable energies to produce H2. Importantly, the WMo-CoP@NM (cathode)||NM (anode) electrolyzer holds an ultra-long stability over 1500 h in 30 wt.% KOH at 65 °C, which confirms their potential for practical applications. DFT calculation shows that the synergistic effect of Mo and W doping can increase the adsorption capability and optimize the electronic structure of CoP species, and therefore efficiently promote HER performance. In short, this work provides the first example via designing robust catalysts to realize the adaptability of AWE for fluctuating renewable energies, which will accelerate the coupling of AWE technology with fluctuating renewable energies for green H2 production.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"36 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144000670","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}

Herein, a new cyano-bridged heterometallic active site catalyst (Cu3[Co(CN)6]2) is proposed to augment CO2 transformation reaction kinetics through electronic localization modulation. Computational simulation and series experiments confirm that the asymmetric electronic distribution in the cyano-bridge promotes distinct electron transfer, which significantly improves the CO2 adsorption ability and catalytic activity of the Co active site with the assistance of the Cu active site, contributing to a remarkable efficiency in driving the CO2 reduction and simultaneously facilitates CO2 evolution reactions.
