Driven by global warming and net zero 2050 policy in the UK, the transportation is a sector that requires heavy decarbonization. The project aims to help design a thermal runaway proof battery pack for electric aircraft and electric automotives. This battery pack is also expected to be safe to operate at a wide range of temperature (-40oC to 50oC). This is enabled by the use of novel immersion cooling system with liquid-gas phasing changing materials. Safety is the first priority for batteries, especially the safety critical applications in automotive and aviation. However, the state-of-art battery technology is not thermal runaway proof, and it suffers from reduced range or accelerated ageing at extreme climate.In this project, we design, model and optimize the novel immersion cooling system so that heat can be quickly dissipated if thermal runaway happens to one or a few cells in the pack. Therefore, thermal runaway and its propagation can be effectively stopped. The current project targets electric automotives with significant improvements both in safety and performance compared to a state-of-the-art battery, with a view to bring the thermal runaway proof technology to the aircrafts as the technology is matured.

在英国的全球变暖和零2050政策的驱动下，运输是一个需要重量脱碳的部门。该项目旨在帮助设计用于电动飞机和电动汽车的热门防止电池组。预计该电池组还可以安全地在广泛的温度（-40oC至50oc）下进行操作。这是通过使用新型的浸入冷却系统和液态加速缩小材料来实现的。安全是电池的首要任务，尤其是汽车和航空中的安全关键应用。但是，最先进的电池技术并不是防热失控的证明，并且在极端气候下的范围降低或加速衰老。在这个项目中，我们设计，型号和优化了新颖的浸入式冷却系统如果在包装中的一个或几个单元格上发生热失控，则消散。因此，可以有效地停止热失控及其传播。与最先进的电池相比，当前的项目针对电动汽车的安全性和性能有了重大改进，以期随着技术的成熟，将热失控技术带入飞机。
