Abstract

Particle emissions released by lithium-ion traction batteries (LIBs) during thermal runaway (TR) are considered to be one of the fire hazard sources for new energy vehicles. Moreover, the particle emissions may persist in the environment and cause damage even after a fire is extinguished. Therefore, the formation mechanisms of the particle emissions from LIBs during TR are summarized firstly in this review. Effects of influencing factors on particle emission characteristics and biotoxicity are also explored. Furthermore, simulation models of LIB particle emissions are summarized. Particle emissions calculated for 2021 to 2023 are presented, and particle emissions from 2024 to 2030 are predicted. Finally, the existing research results and the problems with LIB particle emissions are summarized, and future research challenges and directions are prospected. This review aims to evoke interest in particle emissions from lithium-ion traction batteries during TR and provide a reference for suppressing and managing particle emissions to improve the safety of LIBs and mitigate environmental hazards.

加强对热失控期间锂离子牵引电池颗粒排放的了解：概述与挑战

锂离子牵引电池（LIB）在热失控（TR）过程中释放的颗粒物被认为是新能源汽车的火灾危险源之一。此外，即使在火灾熄灭后，颗粒排放物仍可能在环境中持续存在并造成破坏。因此，本综述首先总结了锂电池在热失控过程中颗粒排放的形成机理。还探讨了影响因素对颗粒排放特性和生物毒性的影响。此外，还总结了锂电池颗粒排放的模拟模型。介绍了 2021 年至 2023 年的粒子排放计算结果，并对 2024 年至 2030 年的粒子排放进行了预测。最后，总结了锂电池颗粒排放的现有研究成果和问题，并展望了未来的研究挑战和方向。本综述旨在唤起人们对 TR 期间锂离子牵引电池颗粒排放的兴趣，并为抑制和管理颗粒排放提供参考，以提高锂离子牵引电池的安全性并减轻环境危害。

期刊介绍： eTransportation is a scholarly journal that aims to advance knowledge in the field of electric transportation. It focuses on all modes of transportation that utilize electricity as their primary source of energy, including electric vehicles, trains, ships, and aircraft. The journal covers all stages of research, development, and testing of new technologies, systems, and devices related to electrical transportation. The journal welcomes the use of simulation and analysis tools at the system, transport, or device level. Its primary emphasis is on the study of the electrical and electronic aspects of transportation systems. However, it also considers research on mechanical parts or subsystems of vehicles if there is a clear interaction with electrical or electronic equipment. Please note that this journal excludes other aspects such as sociological, political, regulatory, or environmental factors from its scope.
