    Powder compression has been utilized in various industries, including pharmaceuticals, foods, metals, and batteries. Although powder properties affect the compact structure, these effects remain unclear. In this study, we used the discrete element method to investigate the effects of particle cohesiveness and plasticity on the compression of bimodal powders. The Edinburgh elastoplastic adhesion model, which considers particle cohesiveness and plastic deformation, was applied as the contact model. The particle plasticity λp was varied from 0 to 0.7. The macroscopic and microscopic properties of the powder compression were investigated. The void fractions of two-component powder mixtures with different plasticities were evaluated. In contrast to that for the elastic model, the void fraction at Vf = 0.5 was smaller than that at Vf = 0.3 for the high plastic condition λp = 0.7). In addition, as the number of fine particles increased, the largest contact type changed in the order of coarse–coarse, coarse–fine, and fine–fine. The plasticity of the particles enhanced the effects of fine particle addition. This study suggests that it is essential to determine the optimal addition ratio of fine particles based on the plastic deformability of the material.

    Research on lithium-ion batteries (Li-ion batteries) has demonstrated that the structure and properties of the separator are critical factors influencing both battery performance and safety. This study investigates three distinct separator structures: foam, non-woven fabric, and uniaxially stretched. The focus is on the interaction between separator structure, thickness, and external conditions to identify key characteristics affecting performance. The foam separator exhibited superior performance, characterized by a more uniform porosity distribution compared to the other structures. This uniformity is crucial for optimizing ion transport and minimizing Li+ concentration gradients, thus improving battery performance. Even at elevated C-rates, the foam separator generated less heat, an essential advantage for maintaining thermal stability during high charge/discharge cycles. Additionally, the study identified a significant challenge under high-pressure conditions, which resulted in a reduced separator thickness (13 μm). Under these conditions, battery capacity became immeasurable at a C-rate of 5. Although the foam separator showed promising features, its limitations under specific operational conditions suggest a need for further optimization. Nevertheless, the findings of this research provide important insights into the role of separator design in addressing challenges related to capacity, thermal stability, and operational limitations in lithium-ion batteries.

    The cathode catalyst layer (CCL) of a polymer electrolyte membrane fuel cell (PEMFC) plays a critical role in determining the overall performance and represents a significant cost factor owing to the use of Pt particles. Optimizing the CCL composition to enhance the PEMFC performance while minimizing Pt loading is a promising approach to lowering costs. Therefore, this study proposes an integrated framework that combines a heterogeneous CCL model with machine learning and a genetic algorithm to optimize CCL composition under low-Pt-loading conditions. The optimized CCL achieves a significant reduction in Pt loading of 56.4 %, from 0.25 to 0.14 mg/cm2, while maintaining a high performance with only a 6.41 % decrease in the maximum power density. The results reveal that the improvement in the optimized CCL can be attributed to the reduced overvoltage caused by proton resistance in the ionomer. This framework offers a powerful tool for the cost-effective CCL design and optimization of PEMFCs.

    The performance of vanadium redox flow batteries (VRFBs) is strongly influenced by the structural properties of the electrode––particularly fiber diameter and compression. This study explores the impact of these parameters on mass transport and electrochemical performance through structural simulations and cyclic voltammetry analysis. Compression was found to increase the specific surface area, enhancing electron transfer rates (k), but also elevated tortuosity and reduced permeability, potentially hindering mass transport. Cyclic voltammetry results revealed that 8 µm fibers exhibited the highest electron transfer rate in the positive electrode, while 10 µm fibers performed optimally in the negative electrode. Polarization curve analysis demonstrated that a mixed configuration—8 µm fibers in the positive electrode and 10 µm fibers in the negative electrode—achieved the most effective balance between reaction kinetics and mass transport. This configuration minimized activation overpotentials and improved sulfuric acid dissociation, resulting in enhanced voltage performance. These findings underscore the critical role of electrode structure optimization in maximizing VRFB efficiency and offer valuable insights for future electrode design advancements.

    All-solid-state batteries (ASSBs) are expected to be next-generation batteries owing to their safety and suitability for high-temperature operation. While traditional lithium-ion batteries use liquid electrolytes that enable easy electrolyte filling after electrode fabrication, ASSBs use solid electrolyte particles. Thus, electrolyte particles must be dispersed alongside the active materials and additives during electrode preparation. The dispersion state of the electrolyte influences subsequent electrode formation and structure; however, experimentally quantitatively controlling and evaluating the dispersion states remains challenging. This study used powder simulation to control the dispersion state quantitatively, based on the aggregation size of solid electrolyte particles. It also evaluated the compression process and the resulting electrode structure.

    To advance the understanding of the mechanical degradation in silicon (Si) anodes, an electrochemical particle simulation model employing the discrete element method is developed. This model integrates lithium-ion (Li-ion) transfer, electrochemical reactions, and charge expansion into a particle physics depiction of a Si anode half-cell. The impact of fabrication pressures and stack pressure on the contact area, cell voltage, and degradation is examined. The charge performance primarily depends on stress overpotential and Li-ion conduction. Conversely, the discharge performance is chiefly constrained by Li-ion conduction, percolation of the electron conducting network, and bottleneck diffusion resistance in areas with minimal contact between the active material (AM) and solid electrolyte (SE). These resistances are markedly reduced by elevating fabrication pressure, which decrease porosity and mitigate delamination between AM and SE. Furthermore, the dynamics of isobaric expansion differ from the constrained case, with the porosity and Li-ion conduction resistance notably increasing alongside the state of charge. The insights gained from this study establish a robust foundation for enhancing the performance and longevity of Si all-solid-state batteries anodes.

    Tablets are the most commonly used dosage form in the pharmaceutical industry, and their properties such as disintegration, dissolution, and portability are influenced by their strength. However, in industry, the mixing fraction of powders to obtain a tablet compact with sufficient strength is determined based on empirical rules. Therefore, a method for predicting tablet strength based on the properties of a single material is required. The objective of this study was to quantitatively evaluate the relationship between the compression properties and tablet strength of powder mixtures. The compression properties of the powder mixtures with different plasticities were evaluated based on the force-displacement curves obtained from the powder compression tests. Heckel and compression energy analyses were performed to evaluate compression properties. During the compression energy analysis, the ratio of plastic deformation energy to elastic deformation energy (Ep/Ee) was assumed to be the plastic deformability of the powder. The quantitative relationship between the compression properties and tensile strength of the tablets was investigated. Based on the obtained relationship and the compression properties of a single material, a prediction equation was put forward for the compression properties of the powder mixture. Subsequently, a correlation equation for tablet strength was proposed by combining the values of K and Ep/Ee obtained from the Heckel and compression energy analyses, respectively. Finally, by substituting the compression properties of the single material and the mass fraction of the plastic material into the proposed equation, the tablet strength of the powder mixture with different plastic deformabilities was predicted.

    Powder compression is the process of obtaining pellets by directly applying pressure to powder beds. The densification phenomenon involving the plastic deformation of particles is still unclear. In this study, the powder compression process of the binary mixture of powder with different plasticity was calculated by using the discrete element method incorporating Edinburgh elasto-plastic adhesion model. The macroscopic and microscopic powder properties were evaluated in the conditions of different volume fraction plastic powders. The calculation method of contact plasticity between elastic and plastic particles, which was proposed in this study, was validated by the data of experimental comparison tests. The result of this study indicated that particle plasticity strongly affected the powder properties, especially contact area inside the powder bed. We hope that this study will be useful for applications where the contact area inside the powder bed is important, such as batteries.

    All-solid-state lithium-ion batteries (ASS-LiB) have garnered attention as the next-generation secondary batteries owing to their high safety and energy densities. The ASS-LiBs are composed of inorganic solid electrolytes, instead of an organic liquid electrolyte. Therefore, interstitial voids deteriorate the battery capacity, which is a serious problem with ASS-LiBs. A straightforward solution to this problem is to fill the voids using smaller particles. However, the particle size control is yet to be established, and there are insufficient studies on particle size control. In this study, nano-sized solid electrolyte particles of Li3PS4 (LPS), which is a typical sulfide solid electrolyte, was synthesized using a liquid-phase shaking method. The nucleation rate of LPS was improved using the submicron-sized Li2S as raw material, which was prepared through wet milling and dissolution-precipitation processes. Consequently, the liquid-phase shaking method with fine Li2S powder was successfully used to synthesize the nano-sized LPS particles with high ionic conductivity.

    In this study, the compression characteristics of bimodal cohesive particles were investigated using a discrete element method (DEM) simulation. The compression and packing processes were simulated under different conditions of size ratios of 1–4 and fine particle mixing ratios of 0–0.5. The cohesive force was expressed using the surface energy proposed by the Johnson-Kendall-Roberts (JKR) cohesion model having a surface energy of 0–0.2 J/m2. The calculated results demonstrated that even in the case of cohesive particles, an increase in the particle size ratio reduced the void fraction of the powder bed during the packing and compression processes. In addition, it was found that the cohesive force decreased the contact number, especially the coarse-coarse contacts, although it had little impact on the void fraction. Our DEM simulations suggested that it is necessary to evaluate the contact numbers even under similar void fractions, which will be essential in the case of different material mixtures, such as all-solid-state batteries.

    全固体電池の内部構造計算によって電極構造を再現し，最短経路探索をベースとした独自コードにより全固体電池の性能を大きく左右する電極内部でのリチウムイオンの伝導経路を評価した。この計算結果は実験検討とも比較され，妥当な評価方法であることがわかり，大気下で不安定な固体電解質を取り扱う必要なく実際の電極構造を計算のみで評価することが可能となった。
