A polyvinylidene fluoride (PVDF) modified proton exchange membrane (PEM) bearing high sulfonic acid density was designed and investigated for water electrolysis application and H2–O2 fuel cell performance. The fabrication method involved ozonation of PVDF, followed by grafting using p-benzoquinone (i.e., Quino-PVDF) and successive sulfonation of Quino-PVDF to acquire the sulfonated Quino-PVDF copolymer. Moreover, a blending modification employing the Nafion™ ionomer was employed to enhance the performance of sulfonated Quino-PVDF based cation exchange membranes (i.e., QuinoCEMs). The membrane with 25 wt/wt% Nafion™/sulfonated Quino-PVDF (i.e., QuinoCEM-0.25) showed good performance in vapor-phase water electrolysis, liquid water electrolysis and direct seawater and achieved maximum current densities of 130, 480 and 240 mA cm−2 over a cell voltage of 1.8 V at 80 °C respectively. Furthermore, the QuinoCEM-0.25 based membrane electrode assembly achieved a peak power density of 400 mW cm−2, comparable to that of Nafion-212™ (i.e., 412 mW cm−2) in proton exchange membrane fuel cells (PEMFCs). Thus, this study highlights the potential of modified PVDF proton exchange membranes as efficient and cost-effective alternatives to commercially available PEMs.

Developing recyclable microcellular rubber foams with excellent photothermal conversion ability can reduce resource waste and harvest solar energy to alleviate the environmental pollution and energy crisis simultaneously. In this work, we propose a novel “one-stone-two-birds” strategy: the constructure of Fe3+ heterodentate coordination between epoxidized natural rubber and polyaniline were successfully confirmed by FT-IR, XPS, and Raman. Through supercritical CO2 foaming technology, recyclable microcellular epoxidized natural rubber/polyaniline/FeCl3 foams (f-EPx) with excellent photothermal conversion were first fabricated and reprocessed. Changing the temperature and FeCl3 content could control the viscoelasticity, subsequently regulating cell size (4.4-9.0 μm) and foam tensile properties (elongation at break up to 710%). The recycling of f-EPx was realized through “cutting-molding-foaming” cycles. After 4 cycles of processing, the 4th reprocessed f-EPx still possessed intact cell structure with 400% elongation at break. Remarkably, Fe3+ heterodentate coordination endowed f-EPx to harvest 92.6% photothermal conversion efficiency and 90.5% shape recovery ratio by photo-triggered shape memory effects. Strikingly, the bird egg wrapped by f-EPx film could be cooked thoroughly under near-infrared light for only 15 minutes, exhibiting potential applications as photo-heating sleeves in solar energy harvesting. This work provides an innovative strategy to fabricating recyclable microcellular rubber foams for clean energy utilization, envisioning the sustainable development of rubber industry.

Exploring low oxidation states of alkaline earth metal elements with natural abundance can be useful for renewable energy applications and is highly desirable. Although alkaline earth metal elements in +1 oxidation states have recently been observed in organometallic compounds, +1 oxidation states in crystal structures are extremely rare. Here, we conduct a comprehensive structure search to find stable two-dimensional (2D) metal monohalides MX crystalline materials composed of alkaline earth metals in +1 oxidation states (M = Be, Mg, Ca, Sr, Ba) and halogens X (X = F, Cl, Br, I) with the aid of first-principles swarm structure search calculations. A subgroup of these 2D MX monolayers exhibits rich topological properties, such as being topological crystalline insulators and high-symmetry-point semimetals. These MX monolayers with inherent metallicity are also promising candidates as anode materials for ion batteries and catalysts for electrochemical water splitting. Various potential synthetic pathways for MX monolayers are proposed using top-down and bottom-up growth approaches, suggesting the feasibility of their experimental realization.

Lithium-ion batteries (LIB) present a global challenge in managing their end-of-life (EOL). As LIB's raw materials are critical and valuable, they are considered a secondary resource. The annual volume of publications and patents on LIB recycling has significantly increased up to 32% compared to 4% in all scientific chemical literature for a decade since 2010, reflecting the emergence of this research topic. In a circular economy context, achieving high recycling efficiency of all LIB components and reusing recycled raw materials for battery production is essential. The increase in recycling efficiency is further promoted by governmental regulations aiming for a carbon neutrality and sustainable society with lower environmental impact. Conventional and destructive recycling methods, pyrometallurgy and hydrometallurgy, focusing on specific metals are insufficient to reach these goals. Instead, this paper discusses the emerging topic of direct recycling, which recovers, regenerates, and reuses the main battery components: electrolyte, negative and positive electrodes to create new LIBs. Although this approach may add complexities to the process, it significantly increases recovery rates, prevents component destruction and minimizes losses. This critical review synthesizes ideas and methods to provide new perspectives on recycling the main components of LIB.

Photocatalytic fuel cells (PFCs) can harness energy from organic waste for electricity generation. However, incorporating CO2 reduction into PFC to achieve carbon neutrality remains significant challenges due to substantial thermodynamic and kinetic barriers. Herein, a PFC is constructed using formate dehydrogenase (FDH)-based biocathode and S-scheme heterojunction TiO2/CdS engineered photoanode. The resulting PFC integrates photoanodic pollutant degradation with bio-cathodic CO2 reduction to achieve formate production rate of 7.13 mol·h-1 with high selectivity and CO2 recovery efficiency of 76.1%, which is the best value in the reported PFC. Furthermore, PFC demonstrates a peak power and current density of 186.3 W cm-2 and 1361.6 A cm-2, respectively. The best performance of PFC is achieved due to the ultrafast electron transfer on the biocathode and the efficient carrier separation of the photoanode. The collaborative dynamics between the photoanode and biocathode lower the CO2 reduction potential, enhancing the reaction kinetics of CO2 reduction to formate.

The conformal surface coating of Ni-rich layered cathode materials is essential for mitigating their interfacial and subsequent structural degradation. Zirconia (ZrO2) coating effectively enhances the surface stability of the cathode owing to its excellent chemical durability; however, the insulating electrical conductivity of ZrO2 increases the electrode resistance of the electrode and triggers efficiency decay. Here, we propose a highly conductive oxygen-deficient black ZrO2−x as a charge-conductive coating material. The black ZrO2−x is uniformly coated onto the Ni-rich LiNi0.8Mn0.1Co0.1O2 (NMC) surface via solvent-free mechanochemical shearing process. Benefiting from the black ZrO2−x coating layer, black ZrO2−x coated NMC shows improved cycling characteristics and better rate capability than both bare NMC and ZrO2 coated NMC. The enhanced electrochemical operations by the conformal coating of black ZrO2−x mainly results from enhanced charge transfer, reduced gas evolution, and mitigated microstructure cracking. Density functional theory calculations confirmed that the defective structure of black ZrO2−x lowers the energy barrier for Li ion transfer, and strong hybridization between Zr in black ZrO2−x and O in NMC mitigates oxygen evolution.

To address the diverse and complex application environments encountered today, the performance requirements for flexible sensing materials have become increasingly stringent. Traditional flexible sensing materials, which typically possess only excellent mechanical properties, can no longer meet these demands. We now seek materials that exhibit a range of additional features, including self-healing capabilities, biodegradabilityand good biocompatibility, to enhance the overall functionality and versatility of flexible sensors. This study successfully synthesized poly (carbonate-chair cyclohexane-urethane) (PCCU) with stable mechanical properties by incorporating a chair conformation structure and dynamic disulfide bonds into the polyurethane backbone. The resulting material demonstrated self-healing capability, antibacterial properties, recyclability, degradability, and biocompatibility. The chair conformation enhanced the material's fatigue resistance and promoted molecular chain mobility, thereby facilitating self-repairing properties. The synthesized polyurethane exhibited high tensile strength (15.09 MPa), high elongation at break (910%), a self-repairing efficiency of 92.75%, low dissipation efficiency (38.46%), 25% mass reduction after 8 weeks of degradation, and efficient antibacterial activity against Staphylococcus aureus and Escherichia coli (92.34% and 88.41%, respectively), with no cytotoxic effects observed. Finally, the polyurethane was encapsulated with conductive ink to validate its sensing capabilities through motion monitoring. This multifunctional polyurethane elastomer enhances the functionality of flexible electronic sensing materials and demonstrates potential applications across multiple domains.

The ever-growing global population, energy scarcity worries, and climate change encourage scientists to explore eco-friendly, and cost-effective energy sources. Energy storage systems, more especially chemistries based on electrochemical reactions such as Li-ion batteries (LIBs), are recognized as one of the greatest effective means of connecting clean energy sources to electrical power grids among the many forms of renewable energy resources, including wind, solar, and wave powers. Regrettably, demand for large-scale commercialization of LIBs tackles serious matters mostly owing to the lack of lithium in the earth. Burgeoning lithium-free batteries such as mono and divalent metal ion batteries (Na-ion batteries (NIBs), K-ion batteries (KIBs), Mg-ion batteries (MIBs), and Ca-ion batteries (CIBs)) could be a suitable candidate for the existing LIBs technology, especially in terms of economics, energy density, and accessibility. With all their advantages such as high ionic conductivity and transference number, quick diffusion for NIBs and KIBs, and high volumetric and gravimetric capacities in CIBs and MIBs, alkali and alkaline-based batteries are very reactive and show low mechanical stability during the charge-discharge process. Therefore, to ease the readers in comparing the differences between mono and divalent metal ion batteries with lithium metal batteries, this review aims to scrutinize the fundamental challenges related to stability issues of electrode-electrolyte interphases (EEIs) in terms of the chemistry and formation mechanism to comprehend the origin of failures in mono and divalent metal-ion batteries. Also, the main instability matters in each part of the mono and divalent metal-ion battery and recent design strategies exploited to improve battery performance are discussed.

Burgeoning lithium-free batteries such as mono and divalent metal ion batteries (Na-ion batteries (NIBs), K-ion batteries (KIBs), Mg-ion batteries (MIBs), and Ca-ion batteries (CIBs)) could be a suitable candidate for the existing LIBs technology, especially in terms of economics, energy density, and accessibility. With all their advantages such as high ionic conductivity and transference number, quick diffusion for NIBs and KIBs, and high volumetric and gravimetric capacities in CIBs and MIBs, alkali and alkaline-based batteries are very reactive and show low mechanical stability during the charge-discharge process. Therefore, to ease the readers in comparing the differences between mono and divalent metal ion batteries with lithium metal batteries, this review aims to scrutinize the fundamental challenges related to stability issues of electrode-electrolyte interphases (EEIs) in terms of the chemistry and formation mechanism to comprehend the origin of failures in mono and divalent metal-ion batteries. Also, the main instability matters in each part of the mono and divalent metal-ion battery and recent design strategies exploited to improve battery performance are discussed.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":null,"pages":null},"PeriodicalIF":11.9,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142405063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
