Summary: A three-dimensional electrochemical-thermal coupled model is developed to study the characteristics of pouch-type lithium-ion batteries under natural convection conditions. The simulation results show that the average particle size of electrodes directly affects the heat generation rate, and the uneven distribution of local current density leads to non-uniform temperature distribution.

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: 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 research investigates the impact of heating temperature on the thermal runaway (TR) of lithium-ion batteries (LIBs). It is found that TR occurs when the heating temperature exceeds 200 degrees Celsius, while only safety venting is observed at 175 degrees Celsius. As the heating temperature increases, the time interval between safety venting and TR decreases, and the temperature difference within the battery decreases. Additionally, the contribution of self-generated heat to trigger TR at different heating temperatures is identified.

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.
