Authors: Hodaei Mohammad Amin , Hamidzadeh Hamid R. 
Published: December 2024

Abstract
This paper presents an analytical method and provides design guidelines for reducing vibrations in fully covered constrained three-layer beams. The analysis is based on the previous well-established studies carried out to investigate the passive vibration control of structures using constrained layer damping treatment. The main objective of this paper is to present guidance for accurate and appropriate practice in the design of a damped cantilever beam using constrained viscoelastic layers subjected to a harmonic force at its free end. The analysis provides the frequency-reacceptance responses, modal natural frequencies, and loss factors. The provided results depict this information for the first three resonance conditions for a wide range of geometries and material properties. The accuracy of the computed results is validated by comparing them with other published results.

Published: December 2024

Abstract
Dust aerosol from the regions of sandstorms is transported by air masses to thousands of kilometers, affecting the optical properties of the atmosphere, climate, and terrestrial natural objects. The northern Caspian region (Kalmykia, the Volga Delta, the Transcaspian lowlands, and northwestern Kazakhstan) is a year-round source of dust aerosol. Based on the data of Mosecomonitoring stations for 2011–2021 we analyzed the episodes of an increase in the level of aerosol pollution in Moscow near-surface air associated with long-range atmospheric transport of dust from the Caspian region. Eight months (about 6%) with the daily PM10 concentration in Moscow higher than MPC value during 3 or more days were revealed. The duration of each episode ranged from 3 to 10 days, and as a total they did not exceed 9% of days per year on average. During those episodes the maximal daily PM10 concentration in the near-surface Moscow air was 2.7 ± 1.1 times higher than the corresponding monthly values. The months with episodes of long-range atmospheric dust transport to Moscow are characterized by 1.9 ± 2.0°C higher air temperature and by 9 ± 13 mm lower precipitation amount relative to the corresponding norms for Moscow.

Sulfide-based all-solid-state batteries (ASSBs) have emerged as promising next-generation energy storage devices due to their high safety and energy density. Si, with its high theoretical capacity (3579 mAh g-1 for Li3.75Si), is a promising anode material for ASSBs. However, its large volume change (~300%) during cycling remains a significant challenge. Recent studies have shown excellent performance of micron-sized pure Si in sulfide-based ASSBs, but inconsistent cycle life characteristics complicate understanding of Si anode degradation mechanisms. To address this, nanolayer Si-coated graphite (Si/Gr) composites have been proposed, but their performance and degradation mechanisms in sulfide-based ASSBs remain unclear.
This study investigates the impact of Si morphological characteristics on the cycle stability of sulfide-based ASSBs and compares the degradation mechanisms of Si/Gr and pure Si composite anodes. Half-cells were fabricated using Si/Gr composites (~10 μm spherical particles, ~50 nm Si coating) and pure Si (1-5 μm). Cycle performance was evaluated for 50 cycles. Microstructural and chemical changes were analyzed using m-XRD, SEM/EDS, XPS, and TEM/EDS/EELS.
The initial capacity of Si/Gr was about 820 mAh g-1, which was higher than that of pure Gr(340 mAh g-1), but after 50 cycles, the cycle retention was 82%, which was faster than that of pure Gr(97%). Pure Si, on the other hand, showed a sharp decrease in capacity to nearly 0% in 10 cycles. The faster degradation of Si/Gr compared to pure Gr was attributed to interactions between Si and Gr within the composite, which had a greater impact than interfacial reactions with the solid electrolyte. Specifically, the Si coating gradually reduced Gr crystallinity during cycling, diminishing lithium storage capacity. For pure Si, crack formation at the Si/SE interface and excessive SEI formation during delithiation led to rapid capacity loss. In conclusion, Si/Gr offered higher capacity than Gr but degraded faster, while the thin Si coating had local volume changes better than micron-sized Si, resulting in higher capacity and improved cycle life.
This research elucidates the degradation mechanisms of Si-C composites in sulfide-based ASSBs and provides insights for optimizing Si-based anodes. These findings offer valuable guidance for developing high-performance sulfide-based ASSBs with enhanced long-term reliability.

The challenges of climate change are becoming increasingly important for society. This is accompanied by a growing need for a wider use of renewable energies, which also increases the need for the possibility of intermediate storage in other forms of energy due to their fluctuating availability. Flow batteries (FB) have the advantage that they store electrical energy chemically in electrolytes and are scalable in terms of power and energy. For a successful broad market launch of FBs, not only the technical performance but also the economic efficiency of the system is important. Known FBs must therefore be technically and economically optimized for specific applications. Not every technically possible improvement has the same positive impact on power or energy-specific costs.
Within the EU project SONAR, a techno-economic model was therefore developed in such a way that it can map inorganic and organic as well as aqueous and non-aqueous FBs and is suitable for automated applications such as machine learning. Based on extensive validation measurements with standardized test cycles, Vanadium FBs and Organic FBs (MV/TEMPOL and AQDS/BQDS) were analyzed in different molarities and compared techno-economically using the model (see Figure 1).
The component-wise sensitivity analyses of that model show battery-specific optimization potentials. With those techno-economically appropriate optimizations can be planned (see Figure 2 and Figure 3).
The additionally developed stand-alone software, into which the model was transferred, can simulate various aqueous flow batteries, which offers versatile application possibilities. Additional relevant areas, such as infrastructure and financing costs, can also be included (see Figure 4). Upscaling of the simulated FBs to industrial applications is possible, as is use for machine learning and high-throughput screening.
In this talk, some results of this techno-economic approach will be presented.

Over the past decades, there has been a notable surge in the adoption of renewable energy sources and techniques for storage. Despite this growth, advancements in energy storage devices have been somewhat limited. Among the various renewable energy options like solar, hydrogen, hydropower, and thermal energy, lithium-ion batteries stand out as a promising solution due to their rapid discharge, stability, capacity, and durability. However, as demands increase for applications such as electric vehicles and smaller electronic devices, which necessitate higher specific capacity, faster charging/discharging rates, and enhanced stability, considerable efforts and resources are being dedicated to developing new and efficient battery materials.
Nanocarbon materials, renowned for their chemical stability and conductivity, have been extensively studied for decades as both cathode and anode components. Their ability to form a conjugated 3D porous network holds great promise for enhancing the kinetic and chemical properties of lithium-ion batteries. In this project, a novel approach is proposed to create a free-standing conjugated 3D porous carbon system utilizing modified graphene and its analogous materials. A new fabrication technique based on microfluidic methods has been developed to reliably produce the 3D aligned porous structure of nanocarbon anodes for lithium-ion batteries. Various 3D free-standing films were produced by optimizing conditions such as precursor suspension concentration, flow rate, and microfluidic channel dimensions. Through comprehensive characterization employing techniques it was confirmed that the 3D porous films possessed anisotropic vertical alignment and macro-porosity, significantly enhancing battery performance.
Notably, the fabricated batteries exhibited substantially increased specific capacity and cyclability compared to those utilizing commercial or unmodified anodes. For instance, by using our 3D free-standing anodic film of MXene/reduced graphene oxide nanocomposite, the resulting battery achieved a specific capacity over 400% higher than its counterparts. This achievement represents a novel advancement, as the preparation of vertically aligned anisotropic 3D free-standing films with suitable dimensions for battery applications, coupled with their superior performance as battery anodes, has not been previously reported.
Thus, the development of the modified microfluidic method, along with the structural and compositional innovations outlined in this project, holds significant potential for revolutionizing the fabrication of high-performance and durable anodes for the lithium-ion battery industry.

Published: December 2024

Proton exchange membrane fuel cells (PEMFCs) are regarded as a highly promising technology for clean and sustainable energy conversion, but face challenges due to their reliance on costly noble metals and sluggish oxygen reduction reaction (ORR) kinetics[1]. Therefore, development of effective catalysts to serve as the alternatives of platinum group metals is required. So far, metal-nitrogen-carbon (M-N-C) materials are considered as the most promising electrocatalysts for ORR[2]. Their performance, however, are still impeded by the low density and accessibility of active metal sites. In this work, we developed a remarkable ORR electrocatalysts by assembling bimetallic CoFe nanoparticles on hierarchically meso-macroporous N-doped carbon nanospheres. This hierarchically structured meso-macroporous N-doped carbon serves as a conductive carrier and provides abundant exposed sites for the active metal species. In turn, the bimetallic CoFe nanoparticles significantly increase the total density of active catalytic sites for ORR. As a result, the optimized CoFe nanoparticles embedded in meso-macroporous N-doped carbon (CoFe@MesoMacroNC) delivered superior ORR activities in both alkali (half-wave potential = 0.943 V vs. RHE) and acid media (half-wave potential = 0.811 V vs. RHE). In addition, when the CoFe@MesoMacroNC was assembled in a Zn-air battery, it showed a higher power density of 155 mW cm-2 than commercial Pt/C (137 mW cm-2) as well as a better stability.

Published: December 2024

Sodium-ions that are dissolved in carbonate-based electrolytes do not intercalate well into graphite. Therefore, alternative anode materials are needed for sodium-ion batteries (SIB). Hard carbon anodes are a promising and widely used negative electrode for SIB, showing reversible gravimetric capacities in the range of 150-350 mAh g-1. [1] Volume changes and parasitic side reactions with the electrolyte are undesirable ageing effects which can happen during cycling and shorten the lifespan of a battery. Operando dilatometry and operando mass spectrometry are useful methods to characterize possible degradation mechanisms.
In this work we analyzed the volume changes of hard carbon electrodes in carbonate electrolytes during cycling with operando dilatometry, paying special attention to irreversible volume changes e. g. due to sodium plating. In addition, we carried out operando mass spectrometry to investigate gaseous substances produced due to the parasitic side reactions at the electrodes. Gas chromatography mass spectrometry (GC-MS) reveals the relevant species. The electrolyte consisted of 1M NaPF6 dissolved in EC:DMC (1:1, by weight). All measurements were carried out in specially developed test setups.
A relationship between the thickness change and voltage profile was established. The thickness changes can be correlated with the different storage mechanisms in the hard carbon electrodes. Additionally, the cyclic formation of the gaseous degradation products could be observed. A possible correlation between gas evolution and thickness change is discussed.
In conclusion, the results of this study contribute to a more detailed understanding of possible degradation mechanisms that occur during cycling of hard carbon anodes in carbonate-based electrolytes. A better understanding of the degradation mechanisms could be used to develop strategies to mitigate the negative influence on battery cycle life.

Development and Characterization of Structural Batteries

Published: December 2024

The structural battery (see figure) is a modern battery concept that integrates mechanical strength and conductive properties of carbon fibres, that hence constitute an intimate part of both electrodes [1]. The core components in a structural battery are composites, developed to provide multiple functions. The structural electrolyte, for instance, needs to both transfer load and conduct ions, whilst a glass fibre reinforced fabric acts as a separator between the electrodes. Good chemical and morphological properties are also crucial at the electrolyte/fiber interface. Similarly to more mature and commercially available batteries, currently tested structural batteries also rely on the conduction of Li ions. It is crucial to realise that highly functional structural batteries can revolutionise the lightweight design of many transport modes. However, such progression requires composite materials able to provide ionic conductivities above 10-4 S/cm and, simultaneously, good mechanical properties, targeting strength higher than 300 MPa and an elastic modulus over 70 GPa. Unfortunately, materials with exactly this set of properties do not exist yet and their development is the focus of our research. In this presentation, I will share recent progress done on the development of structural batteries, emphasising on the results that we have recently obtained from measurements by dielectric spectroscopy, NMR diffusometry, Raman spectroscopy and differential scanning calorimetry [2]. In particular, I will demonstrate the successful integration of protic ionic liquids into the concept of structural battery electrolytes and show the enhancement of local dynamics as an effect of nano-confinement. I will also show results on tests done by battery cycling and on dielectric spectroscopy measurements by which we were able to catch both ionic and electronic conduction.

Mechanistic Insights into the Behavior of Electrolyte Additives That Selectively Suppress Anode Corrosion in Battery Systems
Authors: Phung Theodore , Sinclair Nicholas Scott , Akolkar Rohan 
Published: December 2024

Metallic zinc (Zn) is of great interest as a battery anode material due to its very negative reduction potential, high charge storage capacity, low cost, and compatibility with aqueous electrolytes (acidic and alkaline) [1]. Despite these advantages, Zn-metal anodes are known to spontaneously corrode in aqueous electrolytes leading to a significant loss of stored capacity over long storage times [2]. A common approach to suppress this corrosion is to use additives that can adsorb onto the electrode surface, but many of these compromise the performance of the Zn battery [3]. In this talk, a novel additive, benzyldimethylhexadecylammonium chloride (BDAC), is presented that suppresses corrosion of Zn without impacting high-rate Zn deposition or stripping [4]. This behavior is further explored with slow-scan cyclic voltammetry measurements that show significant hysteresis in the presence of BDAC. The hysteresis implies that the electrode surface exhibits multiple steady states. For example, it can either be covered with additive and become passivated or have little-to-no BDAC and be electrochemically active depending on the applied potential or current. A model is then proposed that incorporates the competition between additive adsorption on a metallic Zn surface and additive deactivation based on metal deposition and stripping rates. Numerical analysis using the model corroborates experimental data and displays how different factors such as the transport rate of additive to the surface and applied current density influence the fate of the electrode’s surface in terms of which stable state it prefers. This work paves the way for the design and operation of electrolyte additives that selectively suppress Zn corrosion without harming battery performance.

Energy storage is becoming increasingly critical for sustaining an energy independent global economy. At present, the major energy eco-system relies primarily on tapping into the earth’s natural oil reserves and gas exports. The Li-ion battery chemistry has evolved over the years since its commercialization by Sony in 1990 and is currently at the forefront of secondary rechargeable battery systems. The field has witnessed burgeoning and an alarming growth in research activity since 1990 with transformative advances made in all areas of cathodes, anodes, and electrolytes. Despite much progress, however, lithiated transition metal oxides and carbon remain the preferred flagship systems that have made it into the commercial arena currently deployed in the hitherto electric vehicles (EVs). The incessant growth and global demand combined with the concomitant emergence of artificial intelligence, countless applications in use and ever evolving, there is an ever-increasing impetus for developing high energy density systems. The intense demand for identifying higher energy density systems has made Li-air and Li-S systems, the preferred actively researched systems of late. The Li-S systems are of particular interest due to the promise of achieving 500 Wh kg-1, a major milestone in meeting the energy density needed for next generation EVs matching and exceeding the performance metrics of the internal combustion engine (ICE).
This presentation will discuss the materials challenges in anode, cathode and the electrolyte areas that must be overcome to reach the grand challenge of 500 Whkg-1. Research progress made in the areas of developing cost-effective and scalable new sulfur and polysulfide confinement systems enabling high sulfur loadings of 4-6 mg/cm2 combined with unique functional electrocatalysts aided by theoretical first principles calculations exhibiting propensities to electro-catalyze Li2S formation will be discussed. Concurrently, progress made in generating new dendrite-free anodes and low-density current collectors for anode free configurations exhibiting areal capacities as high as 15 m Ah/cm2 with stable cycling over 100 cycles as well as electrolyte additives matching the cathode and anode performances will be outlined.
