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: 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: Modern society relies on energy storage systems such as Lithium-ion (Li-ion) batteries, which are sensitive to temperature changes. This study aims to improve the performance of Li-ion batteries by reducing operational temperatures through a novel design of an efficient air-cooling system. The results indicate that increasing air inlet velocity significantly reduces the average air temperature and temperature difference of the battery cells, while the average heat transfer rate of the cooling pack increases monotonically.

Summary: As lithium-ion battery (LIB) research shifts towards high energy density and fast charging batteries, traditional assumptions about battery thermal management around room temperature may not hold true. A comprehensive review of thermal considerations for LIBs targeting high energy density and fast charging is necessary, including optimal thermal conditions, heat transport and generation inside the battery, and thermal management strategies. To maintain temperature uniformity and prevent excessive internal temperature rise, enhancing heat transfer inside the battery and reducing thermal contact resistance between electrodes can significantly improve the effective thermal conductivity of batteries.

Summary: It is crucial to understand the temperature distribution within a battery pack for its impact on capacity loss, power degradation, and safety. This study introduces a novel sensorless method for determining the temperature of a cell by exploiting the relationship between the cell's overpotential and temperature. Through analysis of reference pulses, it is shown that a Δt in the 10 ms to 100 ms range has the greatest sensitivity to temperature and the least dependence on other parameters.

Summary: This study selects Na2S2O3·5H2O (STP) and CH3COONa·3H2O (SAT) as supercooling salt hydrates to preheat lithium-ion batteries. The optimal design is to cover all sides of the battery with a salt hydrate thickness of 8.0 mm at 253.15 K, with heating rates of 0.236 K/s and 0.205 K/s for SAT and STP, respectively. However, as the ambient temperature increases to 273.15 K, the effective utilization of SAT and STP decreases, and a higher discharge rate provides higher effective utilization.
