Summary: The performance of an electric vehicle is greatly influenced by the thermal management of the battery pack. This study investigates the thermal behavior of a Li-ion battery pack and the performance of a liquid-based battery thermal management system using different coolants for different drive cycles. The results show that increasing ambient temperature leads to longer cooling time and higher energy consumption by the liquid-based thermal management system.

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 study investigates the thermal runaway behavior of overcharged LIBs in a low-pressure flight environment. The results show that an increase in overcharge cycles reduces thermal stability and increases the intensity and heat release of thermal runaway in the LIBs. Moreover, the intensity of thermal runaway at 30 kPa is significantly stronger than that at 95 kPa due to the larger differential pressure for combustible release. The intensity and heat release at 30 kPa are weaker than that at 95 kPa due to the lower oxygen content for burning. Electrochemical analysis and disassembly photos confirm the destruction of electrode structure and the deposition of lithium. X-ray computed tomography images and X-ray diffraction patterns suggest that side reactions in the inner layer of the cell are more pronounced than in the outer layer, and internal deformation expands from the inside out.

Summary: The compatibility of LiNi0.8Mn0.1Co0.1O2 (NMC811) with non-flammable water-in-salt electrolytes is investigated. It is found that the enhanced salt concentration effectively diminishes degradation phenomena and that self-discharge reactions lead to irreversible capacity losses.

Summary: Thermal conductivity is a fundamental parameter in battery pack models, but current measurement methods have large errors. This paper presents three novel methods for measuring thermal conductivity and thermal diffusivity with an accuracy of 5.6%. These methods, designed for materials like lithium-ion batteries, maintain a symmetrical thermal boundary condition around the middle of the cell, leading to improved measurement accuracy. These methods represent the future for thermal characterization of lithium-ion batteries.

Summary: This paper illustrates the thermal runaway mechanism of LiNi0.8Co0.1Mn0.1O2 based lithium-ion batteries and proves that the reaction between the cathode and flammable electrolyte is the trigger of thermal runaway accidents. Experimental results demonstrate that the vigorous exothermic reaction is initiated by the liberated oxygen species.
