In this review, the recent research on applications of CNTs in LIBs, including their usage as freestanding anodes, conductive additives, and current collectors, are discussed. Challenges, strategies, and progress are analyzed by selecting typical examples. Particularly, when CNTs are used with relatively large mass fractions, the relevant interfacial electrochemistry in such a CNT-based electrode, which dictates the quality of the resulting solid–electrolyte interface, becomes a concern. Hence, in this review the different lithium-ion adsorption and insertion mechanisms inside and outside of CNTs are compared; the influence of not only CNT structural features (including their length, defect density, diameter, and wall thickness) but also the electrolyte composition on the solid–electrolyte interfacial reactions is analyzed in detail. Strategies to optimize the solid–solid interface between CNTs and the other solid components in various composite electrodes are also covered. By emphasizing the importance of such a structure–performance relationship, the merits and weaknesses of various applications of CNTs in various advanced LIBs are clarified.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"7 2","pages":""},"PeriodicalIF":19.5,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.643","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497144","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}

To enhance energy storage and conversion efficiency, extensive research has been conducted in the academic community on numerous potential materials. Among these materials, metal fluorides have attracted significant attention due to their ionic metal–fluorine bonds and tunable electronic structures, attributed to the highest electronegativity of fluorine in their chemical composition. This makes them promising candidates for future electrochemical applications in various fields. However, metal fluorides encounter various challenges in different application directions. Therefore, we comprehensively review the applications of metal fluorides in the field of energy storage and conversion, aiming to deepen our understanding of their exhibited characteristics in different electrochemical processes. In this paper, we summarize the difficulties and improvement methods encountered in different types of battery applications and several typical electrode optimization strategies in the field of supercapacitors. In the field of water electrolysis, we focus on surface reconstruction and the critical role of fluorine, demonstrating the catalytic performance of metal fluorides from the perspectives of reconstruction mechanism and process analysis. Finally, we provide a summary and outlook for this field, aiming to offer guidance for future breakthroughs in the energy storage and conversion applications of metal fluorides.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"7 1","pages":""},"PeriodicalIF":19.5,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.630","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143120327","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}

Here, we reported a cost-effective, high-strength Janus film through surface optical engineering waste paper with one side decorated by a hydrophobic polymeric cooling coating consisting of micro/nanopore/particle hierarchical structure and the other side coated with hydrophilic MXene nanosheets for heating. The cooling surface demonstrates high solar reflectivity (96.3%) and infrared emissivity (95.5%), resulting in daytime/nighttime sub-ambient radiative cooling of 6°C/8°C with the theoretical cooling power of 100.6 and 138.5 W m−2, respectively. The heating surface exhibits high solar absorptivity (83.7%) and low infrared emissivity (15.2%), resulting in excellent radiative heating capacity for vehicle charging pile (~6.2°C) and solar heating performance. Impressively, the mechanical strength of Janus film increased greatly by 563% compared with that of pristine waste paper, which is helpful for its practical applications in various scenarios for switchable radiative thermal management through mechanical flipping. Energy-saving simulation results reveal that significant total energy savings of up to 32.4 MJ m−2 can be achieved annually (corresponding to the 12.4% saving ratio), showing the immense importance of reducing carbon footprint and promoting carbon neutrality.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"7 1","pages":""},"PeriodicalIF":19.5,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.676","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143120353","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 technology of Li-rechargeable batteries is permeating every corner of our lives as a result of our efforts to reduce the use of carbon energy. Batteries can be seen metaphorically as “living cells”, and approaching the future of that technology requires observing and understanding the real-time phenomena that occur inside battery systems during (electro)chemical reactions. In this regard, in situ analysis techniques have made significant progress toward understanding the basic science of battery systems and finding better performance-improving factors. There are various analysis methods utilizing electromagnetic waves, electrons, and neutrons to perform multifaceted analyses of battery systems from the atomic to the macroscopic scale. Now is the opportune moment to construct a comprehensive guide that facilitates the design of advanced Li-rechargeable battery systems, adopting a highly discerning and all-encompassing approach toward these cutting-edge technologies. In this review article, we discuss and organize the key components such as capabilities, limitations, and practical tips with a comprehensive perspective on various in situ techniques.

Among them, MoB thin film (MoB-TF) exhibits the highest activity toward electrocatalytic hydrogen evolution reaction (HER), displaying a low overpotential (η10 = 191 and 219 mV at 10 mA cm−2) and a small Tafel slope (60.25 and 61.91 mV dec−1) in 0.5 M H2SO4 and 1.0 M KOH, respectively.
