However, issues such as easy electrolyte solubility and low intrinsic conductivity contribute to high polarization and rapid capacity decay. Herein, we have designed a flexible self-supporting cathode based on perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA), interfacial engineering enhanced by polypyrrole (PPy), and carbon nanotubes (CNTs), forming the interconnected and flexible PTCDA/PPy/CNTs using polymerization reaction and vacuum filtration methods, effectively curbing those challenges. When used as the cathode of sodium-ion batteries, PTCDA/PPy/CNTs exhibit excellent rate capability (105.7 mAh g−1 at 20 C), outstanding cycling stability (79.4% capacity retention at 5 C after 500 cycles), and remarkable wide temperature application capability (86.5 mAh g−1 at −30°C and 115.4 mAh g−1 at 60°C). The sodium storage mechanism was verified to be a reversible oxidation reaction between two Na+ ions and carbonyl groups by density functional theory calculations, in situ infrared Fourier transform infrared spectroscopy, and in situ Raman spectroscopy. Surprisingly, the pouch cells based on PTCDA/PPy/CNTs exhibit good mechanical flexibility in various mechanical states. This work inspires more rational designs of flexible and self-supporting organic cathodes, promoting the development of high-performance and wide-temperature adaptable wearable electronic devices.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"6 11","pages":""},"PeriodicalIF":19.5,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.632","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141517052","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}

By dual-doping Ge and Cl into the Li10GeP2S12 (LGPS) framework, we synthesized Ge/Cl-doped LGPS (Li10+xGe1+2xP2−2xS12−xClx, x = 0.3) with an ionic conductivity of 12.4 mS/cm at 25°C, a value that stands among the highest for LGPS-type SEs. This achievement emphasizes the pivotal role of dopant selection in modulating Li-ion transport mechanisms, thereby enhancing SE performance. Our research elucidates the intricate atomic mechanisms responsible for this enhanced ionic conductivity, with a particular focus on the synergistic effects of Ge and Cl dual-doping. Integrating advanced multianalytical techniques, including experiments and atomistic modeling (machine-learning-assisted molecular dynamics simulations and density functional theory calculations), we provide comprehensive insights into the structure–property relationship in Ge/Cl-doped LGPS SEs. Our findings reveal that Cl doping significantly enhances the paddle-wheel dynamics, while Ge doping promotes cooperative Li diffusion through the formation of Li interstitials. This dual-doping approach not only elucidates the structural and functional dynamics of SEs but also paves the way for designing dopants to enhance ionic conductivity. The insights gained from this study offer a strategic direction for developing higher-performance SEs, highlighting the importance of tailored dopant selection in advancing energy storage technologies.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"6 10","pages":""},"PeriodicalIF":19.5,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.594","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141517015","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}

Recently, metal halide perovskites (MHPs) have emerged as promising photocatalysts due to their exceptional photoelectronic properties and low-cost solution processing, enabling successful applications in H2 evolution, CO2 reduction, organic synthesis, and pollutant degradation. Despite these successes, the practical applications of MHPs are limited by their water instability. In this review, the recently developed strategies driving MHP-catalyzed reactions in aqueous media are outlined. We first articulate the structures and properties of MHPs, followed by elaborating on the origin of instability in MHPs. Then, we highlight the advances in solar-driven MHP-based catalytic systems in aqueous solutions, focusing on developing external protection strategies and intrinsically water-stable MHP materials. With each approach offering peculiar sets of advantages and challenges, we conclude by outlining potentially promising opportunities and directions for MHP-based photocatalysis research in aqueous conditions moving forward.

Enormous efforts have been devoted to achieving highly efficient EMI shielding films by enhancing flexibility, lightweight, mechanical robustness, and high shielding efficiency. However, the consideration of the optical properties of these shielding materials is still in its infancy. By incorporating transparency, visual information from protected systems can be preserved for monitoring interior working conditions, and the optical imperceptibility allows nonoffensive and easy cover of shielding materials for both device and biology. There are many materials that can be applied to transparent EMI shields. In particular, two-dimensional transition metal carbide/nitrides (MXenes), possessing the advantages of superior conductivity, optical properties, favorable flexibility, and facile processibility, have become a great candidate. This work reviews the recent research on developing highly efficient and optically transparent EMI shields in a comprehensive way. Materials from MXenes, indium tin oxide, metal, carbon, and conductive polymers are covered, with a focus on the employment of MXene-based composites in transparent EMI shielding. The prospects and challenges for the future development of MXene-based transparent EMI shields are discussed.

This multicomponent strategy favors absorption broadening via additional components. Quaternary OPV (QOPV) blends have four components in three possible configurations: (i) a donor and three acceptors, (ii) two donors and two acceptors, or (iii) three donors and an acceptor. Although quaternary systems have only been relatively recently studied compared to other systems in OPVs, leveraging the synergistic effects of the four components leads to record power conversion efficiencies, currently approaching 20%. QOPVs provide ample material choices for compatibility and channels for charge transfer mechanisms, possibly leading to optimized morphology and orientation. Reviewing recent progress in advancing QOPVs is essential for understanding their contribution to the OPV field. The review mainly discusses research progress in QOPVs with a keen interest in their various configurations, semitransparency, and outdoor and indoor applications. It describes the not-well-understood QOPV's general working mechanism. This review explores high-performance QOPVs based on the fourth component's contribution as a donor, acceptor, or dye molecule and beyond in photovoltaic applications. Finally, there is a discussion around QOPV's outlook and projected future research directions in this field. This review intends to provide an overview of the quaternary systems approach to OPVs and inform current and future researchers on investigating the full spectrum of OPVs.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"6 10","pages":""},"PeriodicalIF":19.5,"publicationDate":"2024-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.579","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141502546","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}

Layered Na2Ti3O7 (NTO), with an open crystal structure, large theoretical capacity, and low working potential, is recognized as one of the prospective anodes for sodium storage. Nevertheless, it suffers from sluggish sodiation kinetics and low (micro)structure stability triggered by a high Na+ diffusion barrier and weak adhesion of [Ti3O7] slabs. Herein, the interlayered local structure of NTO is regulated to solve the above issues, in which parts of interlayered Na+ sites are substituted by H+ (Na2−xHxTi3O7 [NHTO]). Theoretical calculations prove that the NHTO offers lower activation energy for Na+ transports and low interlayer spacings with alleviated Na–Na repulsion and relatively flexible [Ti3O7] slabs to reduce fractural stress. In situ and ex situ characterizations of (micro)structure evolution reveal that NHTO goes through transformation between H-rich and Na-rich phases, resulting in high structure stability and microstructure integrity. The optimal NHTO anode delivers a high capacity of 190.6 mA h g−1 at 0.5 C after 300 cycles and a superior high-rate stability of 90.6 mA h g−1 at 50 C over 10,000 cycles at room temperature.

For the first time, the tunable effective absorption bandwidth can cover the whole test frequency band (2−18 GHz) with the broadest effective absorption bandwidth of 10.8 GHz and the minimum reflection loss of −60.5 dB. Moreover, PI@CNCs/CF possesses excellent heat insulation, infrared stealth, self-cleaning, flame retardant, and acid-alkali corrosion resistance, which endows it high reliability even under various harsh environments and repeated compression testing.
