Summary: This work investigates the lithiation-induced swelling and deformation of three different electrode shapes under the framework of linear elasticity. The study reveals a linear relationship between lithium concentration and hydrostatic stress for all three electrode shapes. It is found that the lithium-induced swelling is proportional to the partial molal volume of lithium and the state of charge, and the swelling rate decreases over time. The constraint and geometrical shape of the electrode play crucial roles in controlling the swelling and stress evolution.

Summary: Thermal management is crucial for lithium-ion batteries due to their heat generation during high-rate charging and discharging. This paper presents a novel manifold immersion (MI) cooling structure inspired by the microchannel structure for chip cooling. Numerical simulation models are used for optimization analysis. The results reveal that the MI cooling structure requires high heat transfer on the lateral surface of batteries rather than the bottom or baffle surface. The cooling capacity is greatly influenced by design parameters such as manifold channel length and battery spacing channel width. Stable wall jet flows contribute to better thermal load and temperature uniformities. The optimized MI cooling structure achieves a maximum temperature of 35.06 degrees C with good temperature uniformity for a lithium-ion battery pack.

Summary: This paper investigates the elastoplastic behavior and fatigue life of the current collector for lithium-ion batteries. The effects of thickness and yield stress on elastoplastic behavior are discussed, along with the influence of different collector thicknesses on stress in the active layer. Fatigue life is predicted based on different elastoplastic behaviors. The results suggest that decreasing current collector thickness or yield stress leads to a shift from plastic shakedown to cyclic plasticity, with the peak stress in the collector increasing and stress in the active layer decreasing. CP not only relieves stress in the active layer but also improves the battery's energy density. These findings provide new insights into the fatigue and elastoplastic behavior of LIBs collectors.

Summary: In this work, the lithiation mechanism of green phosphorus (GP) with different layers as anode materials in Li-ion batteries was investigated using first-principles calculations. The results showed that single-layer GP has a higher specific capacity and faster Li diffusion rate compared to double-layer and bulk GP. The lithiation voltage also increases with the number of GP layers. Additionally, the specific capacity of GP is higher than that of black phosphorus anode.

Summary: The study proposes a coupled heating method using phase change materials (PCM) and heat films (HF) to warm up traction batteries at low temperatures, comparing two heating modes for effectiveness. It was found that while Heating Mode II had a faster heating rate, it had poorer temperature uniformity compared to Heating Mode I. Various factors affecting the heating performance of the coupled PCM/HF method were also investigated.

Summary: Research shows that lithium-ion batteries, especially those with silicon-based anodes, undergo significant volume changes during charge and discharge. This contradicts the expected decrease in stress as the battery volume decreases. By combining experimental measurements and an improved single-particle model, this study reveals that the large volume change of the anode material and the limited diffusion of lithium-ion in the active particles result in uneven concentration distribution and anomalous stress changes. The rupture of particles during cycling also contributes to increased diffusion channels and diffusion coefficient, enabling the prediction of battery health and reducing prediction complexity.

Summary: This study comprehensively investigates the cyclic plasticity behaviour of the LiNixMnyCozO2 electrode subjected to cyclic lithiation/delithiation under constant mechanical load. The shakedown, ratcheting, and fatigue analyses were performed using direct numerical techniques, while coin cell electrochemical experiments were conducted to support the analysis. The effects of coating thickness on shakedown and ratcheting response, as well as the strain-fatigue life curve to predict active coating life, were studied. The numerical results confirmed the presence of low cycle fatigue at the center and ratcheting mechanism at the edge of the cathode, consistent with experimental findings.

Summary: The current lithium ion battery technology poses safety risks, with the development of solid ceramic electrolytes offering a safer alternative for the next generation of all-solid-state batteries. However, the lithium diffusion behavior in these solid electrolytes and transport properties at the metal anode interface are not well understood. The proposed methodology aims to obtain lithium diffusion coefficients of bulk solid ceramic electrolytes and study their interfaces with electrodes for further optimization and performance enhancement in solid-state lithium batteries and hybrid systems.

Summary: Lithium-ion batteries are important technologies for improving energy storage. This study investigates the effects of ambient temperature, discharge rate, depth-of-discharge, and convective heat transfer coefficient on the maximum battery temperature and maximum battery temperature difference. The results show that the ambient temperature has the greatest influence on the battery temperature, while the depth-of-discharge has negligible effect. The maximum battery temperature difference is mainly determined by the discharge rate and the convective heat transfer coefficient.

Summary: In this study, a battery module consisting of sixteen 38120-type lithium-ion batteries was immersed in mineral oil to investigate the cooling effectiveness under various conditions. The results showed that increasing battery spacing and coolant flow rate can effectively reduce the temperature rise of the battery module. However, increasing flow rate also imposes restriction on the cooling efficiency due to pressure drop. The findings provide insights into the oil-immersed battery cooling system and may stimulate further development of BTMSs based on immersion cooling.
