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: Although lithium metal anodes are expected to increase the energy density of next-generation batteries, the growth of dendrites during charge hampers their widespread implementation. Composite solid electrolytes with ceramic particles embedded in a polymer matrix show promise in preventing dendrites, but the differing properties of the polymer and ceramic domains can lead to nonuniform Li deposition and dendrite propagation. Computational examination reveals that optimizing the microstructure at the interface and incorporating interlayers can mitigate the issue, providing guidance for experimental approaches to prevent dendrites in composite electrolytes.

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.

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: The study focused on the simulation and analysis of thermal runaway in batteries, finding that batteries with Li4Ti5O12 and LiFePO4 materials showed better thermal safety and stability. Increasing separator melting temperature can delay the occurrence of thermal runaway, while increasing air velocity and reducing ambient temperature help batteries stay in a steady state.
