Summary: Manufacturing defects can result in thermal runaway in batteries, posing serious safety risks in electric vehicles and energy storage systems. A study found that complete tearing of the anode tab poses the greatest hazard to battery safety, as it can lead to lithium plating phenomenon. The mechanism behind this phenomenon is identified as a combination of high electrolyte-phase electrical potential and gradual accumulation of lithium intercalation at the anode edge.

Summary: Thermal runaway, caused by lithium plating in low-temperature cycling LIBs, is a significant hazard that hinders the application of LIBs in electric vehicles and energy storage systems. This study developed a thermal runaway model that includes the exothermic reaction between metal lithium and electrolyte to account for the aging effect. Validation tests confirmed the effectiveness of the model. The results revealed a three-stage process for thermal runaway and demonstrated that the reaction between plated lithium and electrolyte at around 140 degrees C accelerates the onset of thermal runaway.

Summary: This work investigates the influence of low temperatures and current rates on lithium (Li) plating in lithium-ion batteries (LIBs) through electrochemical tests, material characterization, and numerical analysis. The results show that at lower temperatures and higher current rates, the battery charging process shifts from normal intercalation to Li plating, which eventually leads to failure. The morphology observations reveal the growth process of Li plating, and quantitative analysis reveals the dynamic pattern under long-term cycles. The study provides detailed information on the range and growth process of Li plating, which can be used for practical prediction and regulation.

Summary: Graphite anodes in practical applications often suffer from Li plating, causing capacity fade and safety hazards. This study monitored the secondary gas evolution behavior during Li plating process using OEMS, and detected the local microscale Li plating on graphite anode in situ for early safety warnings. The distribution of irreversible capacity loss under Li plating conditions was accurately quantified using TMS. The effect of typical VC/FEC additives on Li plating was recognized based on OEMS/TMS results, and it was found that these additives could reduce the loss of dead Li capacity.

Summary: Current research focuses on lithium-ion battery cells with high-energy density and good fast charging properties. Increasing mass loadings is one approach to achieve high-energy densities, but thick electrodes face transport limitations that result in performance drop. Overcoming these limitations can be achieved through the use of different active materials and a two-layer coating of the anode to reduce ionic resistance and enable faster lithiation of the anode. This approach has shown promising results in terms of increased electrical conductivity and capacity retention.

Summary: In this study, beta-lactoglobulin solutions were mechanically stressed using glass beads at high temperatures and low pH value to investigate the effect of mechanical stressing and surfaces on amyloid aggregation kinetics. The findings provide valuable insights into the role of specific mechanical factors in facilitating the assembly of building blocks for efficient production of functional amyloid aggregates. The use of different diameters of glass beads and shaking frequencies allowed for the manipulation of mechanical stress energy, which was quantified using CFD-DEM simulations. Surface effects were examined by modifying the hydrophobicity and surface roughness of the glass beads. The analysis of amyloid aggregates and bead surfaces was performed using ThT-assay, AFM, and ATR-FTIR techniques.

Summary: Modeling the structural and mechanical properties of tablets with multiple components using minimal experimental data is of great interest to minimize time and cost in the development of new tablet formulations. Most available models use compressibility and compactibility of constituent components and mixing rules to predict tablet properties. However, these models are limited to single materials, excluding lubricants. This study combines compaction and lubrication models to systematically predict properties of lubricated multi-component tablets.

Summary: The aim of this study was to investigate the deformation behavior of non-spherical particles during high-load compaction using the multi-contact discrete element method (MC-DEM). The bonded multi-sphere method (BMS), which incorporates intragranular bonds between particles, and the conventional multi-sphere (CMS), where overlaps between particles are allowed to form a rigid body, were used. The results showed that the BMS method was able to handle large elastic deformations and achieved good agreement with experimental data, while the CMS approach had limitations in capturing the compression behavior of a single rubber sphere.

Summary: Tablets are the preferred dosage form for many active pharmaceutical ingredients and viable probiotic microorganisms due to their convenience, safe dosing, and cost-effective production. In this study, granules with viable yeast cells were tableted using a compaction simulator, and the effect of compression stress, speed, consolidation time, and dwell time on tablet properties and microbial survival was investigated. Higher compression stress resulted in lower porosity and higher tensile strength, which had a detrimental effect on microbial survival but improved tablet quality. Prolonged dwell time reduced porosity and survival rates but increased tensile strength, while consolidation time had no significant influence on tablet quality attributes.

Summary: In order to ensure the effectiveness of probiotic microorganisms when administered to patients in sufficient doses, dry dosage forms are preferred, particularly tablets. The drying process must be as gentle as possible. In this study, Saccharomyces cerevisiae was dried using spray drying and various additives and process parameters were investigated to improve yeast cell survival. The use of protective additives was found to be essential and the outlet temperature during drying determined the survival rate. Subsequent compression of the spray-dried yeast reduced viability, but tabletability of the yeast protectant particles was good, providing insights into cell inactivation during tableting.

Summary: To achieve the commercialization of solid-state batteries, further improvement in the properties of solid electrolytes is needed. The hybrid solid electrolyte approach, which combines different solid electrolyte classes, is being systematically investigated. However, mixing thiophosphate or oxide filler particles into the matrix does not improve the electrochemical properties. Silanization of the thiophosphate filler particles significantly increases the ionic conductivity, and the surface structure of the filler particles affects the overall conductivity of the hybrid solid electrolyte. These findings emphasize the importance of tailored filler design in solid-state battery applications.

Summary: In this study, in-depth analyses were conducted to investigate the ageing of negative electrodes with different particle size distributions. The analyses included discharge behaviour, electrochemical impedance analysis, and for the first time, nonlinear frequency response analysis. The results showed that the ageing impacts were more significant on the positive electrode for fine to medium-sized particles, leading to increased impedance and nonlinear responses. However, for coarse and broad negative particles, the impedance and nonlinear responses at negative electrodes decreased due to improved kinetics from micro-cracking. Additionally, the nature of the charge transfer process during ageing was found to change: it became asymmetric for fine and medium-sized negative particles at the positive electrode, while it became symmetric for coarse and broad negative particles at the negative electrode.

Summary: This study comprehensively investigated the impact of Si content and particle size on the particulate and electrode properties of Si@Gr composites. It was found that both parameters significantly influenced the specific surface area (SSA) of particles, which in turn correlated with the initial capacities and coulombic efficiencies (ICEs). Furthermore, changes in pore size distribution and electrical conductivity were observed. The built full cells exhibited high initial capacities (>150 mAh g(-1)), good rate capability (75% at 1 C, 50% at 2 C) and ICEs (>80%). The energy density increased by 32% at 15 wt.% Si compared to graphite, indicating the future potential of Si. Additionally, the impact of a carbon coating on Si@Gr/C composites was investigated, showing reduced SSA, improved particle stability, and higher capacity retention. Hence, this study emphasizes the importance of investigating the particulate properties of Si anodes.
