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: 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.

Summary: The study investigates a lithium-ion battery heat management system using a heat pipe, and experimentally explores its performance. The experimental results show that while increasing ambient temperature leads to a rise in battery surface temperature, the decrease in thermal resistance of the heat pipe moderates this effect and controls the battery surface temperature with forced convection, distributing temperature uniformly. The use of the heat pipe helps maintain more stable temperature conditions with lower fluctuations in consecutive battery cycles.

Summary: Thermal runaway is a major safety obstacle for the development of electric vehicles and energy storage systems. This study investigates the thermal runaway behavior and propagation of lithium-ion batteries with different tab connection methods using an electro-thermal model. The results show that the thermal runaway behavior and propagation are influenced by factors such as C-rates and tab connection modes. Tab overheating is found to be more dangerous for triggering thermal runaway compared to other heating strategies.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: An efficient phase inversion-impregnation approach is developed to fabricate BaO-decorated Ni8 mol% YSZ anode-supported tubular solid oxide fuel cells (SOFCs) with anti-coking properties. BaO nanoislands are successfully introduced inside the Ni-YSZ anode, leading to higher peak power densities and improved stability in methane fuel. Density functional theory calculations suggest that the loading of BaO nanoislands facilitates carbon elimination by capturing and dissociating H2O molecules to generate OH.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
