#Selectedpapers in #Batteries_MDPI in topic "Lithium-ion Batteries" "Modification of Single-Walled Carbon Nanotube Networks Anodes for Application in Aqueous Lithium-Ion Batteries" 🔗 Read the full article: https://brnw.ch/21wKQap 👉 Check out more papers in topic "Lithium-ion Batteries": https://brnw.ch/21wKQan Abstract The changes in global energy trends and the high demand for secondary power sources, have led to a renewed interest in aqueous lithium-ion batteries. The selection of a suitable anode for aqueous media is a difficult task because many anode materials have poor cycling performance due to side reactions with water or dissolved oxygen. An effective method for improving the characteristics of anodes in aqueous electrolyte solutions is adding carbon nanotubes (CNTs) to the electrode materials. For a better comprehension of the mechanism of energy accumulation and the reasons for the loss of capacity during the cycling of chemical current sources, it is necessary to understand the behaviour of the constituent components of the anodes. Although CNTs are well studied theoretically and experimentally, there is no information about their behaviour in aqueous solutions during the intercalation/deintercalation of lithium ions. This work reveals the mechanism of operation of untreated and annealed single-walled carbon nanotubes (SWCNT) anodes during the intercalation/deintercalation of Li+ from an aqueous 5 M LiNO3 electrolyte. The presence of -COOH groups on the surface of untreated SWCNTs is the reason for the low discharge capacity of the SWCNT anode in 5 M LiNO3 (3 mAh g−1 after 100 cycles). Their performance was improved by annealing in a hydrogen atmosphere, which selectively removed the -COOH groups and increased the discharge capacity of SWCNT by a factor of 10 (33 mAh g−1 after 100 cycles).

New potential has been discovered in the field of large-scale energy storage, promising significant breakthroughs！ Lithium−sulfur (Li−S) battery is a highly promising candidate for the next−generation battery system. However, the shuttle effect of polysulfides or the dendrites and side reactions of lithium metal anodes limit the cycle life of batteries. The team led by Professor Yunhui Huang, the Chief Scientist of Topsound, and the team led by Professor Zhen Li from Huazhong University of Science and Technology have jointly constructed a Li−S pouch cell with sulfurized pyrolyzed poly(acrylonitrile) (SPAN) as the cathode and graphite (Gr) as the anode, introducing lithium−ions through a facile in−situ pre−lithiation method. In carbonate−based electrolytes, the SPAN cathode can avoid the shuttle effect, while the Gr anode can exclude the interference of lithium metal. This design is expected to fundamentally improve the long cycle stability of the Li−S pouch cells and it has great potential in the field of large scale energy storage due to its absence of transition metal elements. Meanwhile, the related research paper titled "Lithium−sulfur pouch cells with 99% capacity retention for 1000 cycles" has also been successfully published in the journal Energy & Environmental Science.

Dear #electrochemistry and #energy storage communities   This week, we selected two recent #openaccess peer-reviewed #articles for the “Energy Editors’ Highlights” page of Nature Communications (the only fully open-access Nature-branded journal of Springer Nature Group and Nature Portfolio).   The first is a commentary article written by Alessandro Innocenti, Stefano Passerini and co-authors focusing on Zn and Li’s availability for use in #batteries. They use techno-economic analysis and simulations to critically discuss the accuracy of the claims about sustainability and cost-effectiveness of zinc compared to lithium for secondary battery systems. 🔋⚡🪫⚡   The second is a research article by Jack Aspinall, Mauro Pasta and co-authors. They explore the compatibility of lithium-magnesium alloy electrodes with a Li6PS5Cl solid-state #electrolyte using cutting-edge physicochemical and electrochemical characterizations. The authors demonstrate the role of Mg content in the alloy for possible practical all-solid-state battery applications. 🔬🔋⚡🪫   As a scientist and in-house editor, I really enjoyed reading and editing these papers as they offer practical perspectives on different scales for the future development of aqueous and non-aqueous battery systems. 😊   I would be happy to read your thoughts about these research works in the comments, and if you haven’t already read these articles, I strongly recommend doing it. Also, if you are interested in the latest research on future zinc-based aqueous battery development, I suggest looking at our recent collection.   You can find the links to the articles, “Energy Editors’ Highlights” page and zinc batteries collection in the comments 👇👇👇👇

I am glad to share our recently published review entitled “MXenes the future of solid-state supercapacitors: Status, challenges, prospects and applications”. Which summarizes the developments in MXene-based energy storage. Technological advancements have led to a growing demand for energy storage systems, with MXene being the most popular material due to its high conductivity, flexibility, mechanical properties, hydrophilicity, and electrochemical nature. MXene is used in various applications, including supercapacitors, batteries, and biosensors. Researchers are developing MXene microelectrodes for micro-sized energy storage devices (MESDs) using various microfabrication processes. This review discusses the state-of-the-art, challenges, and future prospects of MXene-based energy storage. https://lnkd.in/eYk2tWBb

New publication alert! Grimaldi et al. have just published an interesting article on the photostability of 2D and quasi-2D hybrid organic-inorganic perovskites (HOIPs). https://lnkd.in/gFB5v8xt For the past 15 years, perovskite research has focused on improving the photovoltaic power conversion efficiency of 3D perovskites, which are now nearing the performance of state-of-the-art silicon photovoltaics. However, these materials face stability challenges under certain environmental conditions. Recent research shows that certain 2D and quasi-2D perovskites offer enhanced stability due to their large, organic sublattices. In this study, Grimaldi et al. examine the photostability of a set of related 2D and quasi-2D perovskites, using a range of analytical techniques (SEM/EDX, XRF, FTIR, and photoluminescence measurements). They tested these materials under various atmospheric conditions, namely atmospheric air, nitrogen, and dry air, while exposing them to laser illumination to understand how degradation occurs. Their findings highlight oxygen's crucial role in the photodegradation of these materials, and they show how adding a capping layer can significantly slow down photoluminescence decay. For anyone interested in enhancing the stability of lower-dimensional perovskites like I am, this paper is both thorough and thought-provoking. While certain 2D structures may be more stable than 3D counterparts, there is still much work to be done in designing structures with greater environmental photostability and effective passivation strategies for broader implementation in photovoltaic devices and renewable energy technologies.

Alhamdulillah, Another work from my Ph.D. research has been published in Solar RRL journal (WILEY Online Library). I am so grateful to all co-authors, especially my supervisor Dr. Yan for supporting me. Growing the antimony selenide (Sb2Se3) nanoribbons perpendicular [001] direction to the substrate is crucial for easy charge carrier transportation, and it has been a major challenge so far. In this project, we developed solution-processed Sb2(S,Se)3 nanopillars-like structure to assist vertical grain growth of Sb2Se3 nanoribbons, that yielded high quality, compact and columnar Sb2Se3 thin films. This approach improved the solar cell power conversion efficiency by almost 34.28%. Please have a look at my paper if you find it interesting. #Semiconductor_chalcogenides #ThinFilm #SolarCell #Photovoltaic https://lnkd.in/g-h95ZYK
