In article cey2.647, Wang et al. synthesized [Me2NH2]V3O7 (MNVO) using a hydrothermal method. This layered vanadate features expended layer spacing and enhanced pH resistance. Both experimental and theoretical analyses reveal that the interlayer ionic and hydrogen bonding interactions, along with synergies from oxygen vacancy, enhance electronic conductivity and reduce the ion diffusion energy barrier. These improvements boost the material's capacity for H+/Zn2+ co-insertion in energy storage. As a result, aqueous zinc-ion batteries with MNVO as the cathode demonstrate high capacity and excellent cycling stability in acidic electrolytes.\u0000\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture>\u0000 </div>\u0000 </figure>","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"7 2","pages":""},"PeriodicalIF":19.5,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.70008","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497343","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}

However, their applicability has been hindered by low output discharge potential, high discharge polarizations, and singular aqueous configuration. To address these, the catalyst with faster oxygen reduction reaction (ORR) kinetic rate, nitrogen-doped carbon materials functionalized with FeMo metal clusters (FeMo-NC), was designed in acid electrolyte and thus high output voltage and energy density SABs with asymmetric-electrolytes have been developed. This innovative design aligns the reaction rates of the cathode and anode in SABs, achieving stable discharge around 1.7 V for 188 h. Furthermore, an all-in-one quasi-solid-state SAB (QSSSAB) was first developed using a suitable acid–base gel electrolyte. This all-in-one QSSSAB showcases good safety, low cost, and portability, with open-circuit voltage of 1.6 V and energy density of 300.2 Wh kg−1, surpassing the energy density of most previously reported aqueous SABs. In terms of application, these compact all-in-one QSSSABs can provide stable and reliable power support for portable small electronic devices (such as electronic players, diodes, and electronic watches).","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"7 2","pages":""},"PeriodicalIF":19.5,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.661","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497076","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}

Herein, experimental and numerical studies on the geometric optimization of a hygroscopic-membrane heat sink (HMHS) are conducted. The HMHS is based on water evaporation from a membrane-encapsulated hygroscopic salt solution, in which pin fins are used for thermal conductivity enhancement. A comprehensive heat and mass transfer model is developed and validated. To obtain the HMHS configuration with the maximum cooling performance, an approach that couples the Taguchi method with numerical simulations is utilized. The contribution ratio of each design factor is determined. Experimentally validated results demonstrate that the maximum temperature reduction provided by the HMHS can be further improved from 15.5°C to 17.8°C after optimization, achieving a temperature reduction of up to 21°C at a fixed heat flux of 25 kW/m2 when compared with a similarly sized fin heat sink. Remarkably, the optimized HMHS extends the effective cooling time by ∼343% compared with traditional phase-change materials, achieving a maximum temperature reduction ranging from 7.0°C to 20.4°C. Meanwhile, the effective heat transfer coefficient achieved is comparable with that of forced liquid cooling. Our findings suggest that the proposed cooling approach provides a new pathway for intermittent thermal management, which is expected to be used for thermal regulation of electronics, batteries, photovoltaic panels, and LED lights.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"7 2","pages":""},"PeriodicalIF":19.5,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.665","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497075","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}

In this study, we propose a novel approach called “similar stacking” for stress modulation, achieved through the loading of Co2P on Ni2P (Ni2P/Co2P). Theoretical simulations reveal that the compressive strain induced by Co2P influences orbital overlap and electron transfer with hydrogen atoms. Furthermore, the number of stacked layers can be adjusted by varying the precursor soaking time, which further modulates the strain range and hydrogen adsorption. Under a 2-h soaking condition, the strain effect proves favorable for efficient hydrogen production. Experimental characterizations using X-ray diffraction, high-angel annular dark-field scanning transmission election microscope (HAADF-STEM), and X-ray absorption near-edge structure spectroscopy successfully demonstrate lattice contraction of Co2P and bond length shortening of Co–P. Remarkably, our catalyst shows an ultrahigh current density of 1 A cm−2 at an overpotential of only 388 mV, surpassing that of commercial Pt/C, while maintaining long-term stability. This material design strategy of similar stacking opens up new avenues of strain modulation and the deeper development of electrocatalysts.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"7 2","pages":""},"PeriodicalIF":19.5,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.668","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497021","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}

However, limitations in the morphology of heterostructures prepared by hydrothermal reactions or molten salt-assisted strategies make it challenging to directly assess charge distribution and evaluate a single interface's hydrogen evolution reaction (HER) performance. Here, we prepared two-dimensional MoO2/MoS2 step heterostructures with a large specific surface area by the chemical vapor deposition method. Surface Kelvin probe force microscopy and electrical transport measurement verified the asymmetric charge distribution at a single interface. By fabricating a series of micro on-chip electrocatalytic devices, we investigate the HER performance for a single interface and confirm that the interface is essential for superior catalytic performance. We experimentally confirmed that the enhancement of the HER performance of step heterostructure is attributed to the asymmetric charge distribution at the interface. This work lays a foundation for designing highly efficient catalytic systems based on step heterostructures.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"7 2","pages":""},"PeriodicalIF":19.5,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.663","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497022","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}

However, structural instability and complex phase transitions during electrochemical cycling pose significant challenges to their practical applications. Employing cation substitution serves as a straightforward yet effective strategy for stabilizing the structure and improving the kinetics of the active material. In this study, we introduce a Ni-rich honeycomb-layered Na2+xNi2TeO6 (NNTO) cathode material with variable sodium content (x = 0, 0.03, 0.05, 0.10). Physicochemical characterizations reveal that excess sodium content at the atomic scale modifies the surface and suppresses phase transitions, while preserving the crystal structure. This results in enhanced cyclic performance and improved electrochemical kinetics at room temperature. Furthermore, we investigate the performance of the NNTO cathode material containing 10% excess sodium at a relatively high temperature of 60°C, where it exhibits 71.6% capacity retention compared to 60% for the pristine. Overall, our results confirm that a preconstructed surface layer (induced by excess sodium) effectively safeguards the Ni-based cathode material from surface degradation and phase transitions during the electrochemical processes, thus exhibiting superior capacity retention relative to the pristine NNTO cathode. This study of the correlation between structure and performance can potentially be applied to the commercialization of SIBs.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"7 2","pages":""},"PeriodicalIF":19.5,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.658","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497020","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}
