Towards Safer Battery Packs for Transport Industry

英国承诺到2050年实现净零排放。运输部门是其中的重要组成部分，这导致了汽车和/或航空动力系统电气化的出现。特别是在运输领域，大型电池组的障碍是类似的，成本，耐用性和安全性。该项目的主要重点将放在大格式电池组的安全方面。人们对热失控模型背后的物理学以及电池故障期间发生的实际反应缺乏了解。因此，在大多数情况下，来自一个单元的数据/模型将无法转移到另一个单元。该项目的目的是通过开发基于物理的热失控模型并量化热量和释放的气体来弥补文献中的空白。此外，使用经过验证的模型来减轻故障情况下的热失控/热传播，并找到避免电池组爆炸的解决方案。

The UK is committed to achieve net zero emissions by 2050. The transport sector is a significant part of it, and this has led to the emergence of electrification of power trains in automotive and/or aviation. With transport sector specifically, the hurdles of large format battery packs are similar, cost, durability, and safety. The main focus of this project will be on the safety side of a large format battery pack. There is a lack of understanding regarding the physics behind thermal runaway models and the actual reactions that happen during a battery failure. Therefore, in most cases the data/model from one cell won't be transferable to another. The aim of this project is to bridge the gaps in the literature firstly by developing physics-based models of the thermal runaway and quantifying the heat and released gas. Furthermore, using the validated models to mitigate thermal runaway/thermal propagation in case of a failure, and finding solutions to avoid battery pack explosion.
