Abstract - Li-ion batteries have emerged as one of the most alluring energy sources, particularly in the transportation industry, as worries about carbon emissions and the ensuing climate effects grow. An efficient thermal management system is necessary for Li-ion batteries in order to guarantee high efficiency, prevent capacity degradation, and remove safety concerns. Heat pipe-based thermal management systems have been widely utilized to regulate the temperature of Li-ion batteries because they can provide exceptional cooling performance in a small area. Based on research conducted over the previous 20 years, this study provides a thorough evaluation of the thermal management systems of Li-ion batteries that use four different types of heat pipes: flat single channel heat pipes, oscillating heat pipes, flexible heat pipes, and microchannel heat pipes. To give researchers and engineers a comprehensive understanding, the impacts of many influencing factors on the cooling performance and thermal runaway behavior of Li-ion batteries are covered in detail. According to the findings, water spray cooling has the potential to outperform forced air cooling and water bath cooling for all kinds of heat pipe-based thermal management systems. Its energy usage is also clearly lower than that of forced air cooling.
