Hx LIFE Foils manufacturing scale up for next generation automotive EV batteries

满足政府时间表对汽车行业日益增长的电气化需求，将需要增加电动汽车电池的安全性、可靠性、成本效益和可循环性。在Reaction Engine，我们开发了一种创新技术，使电池的被动热管理成为可能。这项名为HX LIFE FOILS的技术是一种导热系数非常高的材料，可以插入电池之间来冷却电池，并且可以为大多数袋状、棱柱状和圆柱形电池塑造和调整大小。我们已经在测试中展示了以下属性：*安全性：改善热失控的遏制*低质量以获得高比功率和高能量*高抽热率：优于大多数活跃的冷却系统在下一代汽车电池中部署箔片将显著提高汽车电动汽车的安全性和性能，并简化模块和组件的设计和架构。Hx Life箔片旨在以低成本大量制造，以满足汽车电池组的需求。以前与MTC的工作强调了这一过程中的改进，以降低风险和成本。因此，该项目包括优化流程的积木，并通过建设一条试点生产线，启动第一批中低规模的生产，使铝箔的年产量达到10000台，同时实现MRL6-7。这将支持原型的生产，并为下一次扩大规模提供学习，目标是大量生产(每年100万片)。联合体将由反应引擎作为箔的开发商和制造商领导，并将包括制造技术中心(MTC)作为合作伙伴。该计划将于2022年9月1日开始，2023年12月底完成。

Meeting the increasing need of electrification for the automotive industry by the government timescales will require an increase in the safety, reliability, cost effectiveness and cyclability of EV batteries.At Reaction Engines we have developed an innovative technology that enables the passive thermal management of battery cells. The technology, called Hx LIFE Foils, is a very high thermal conductivity material that inserts itself between the cells to cool them and can be shaped and sized for most pouch, prismatic and cylindrical cells. We have demonstrated on test the following attributes:* Safety: Improve containment of thermal runaway* Low mass for high specific power and energy* High rate of heat extraction: superior heat extraction to most active cooling systemsDeploying the Foils in the next generation automotive batteries will significantly improve the safety and performance of automotive EV's as well as simplifying the design and architecture of the modules and packs.Hx Life Foils have been designed to be made in very high volume at low cost to meet the demand for automotive battery packs. Previous work with the MTC has highlighted improvements in the process to reduce risks and costs. The project therefore consists in optimising the building blocks of the process and initiating a first scale up to low-medium scale production by building a pilot line that will allow production of the Foils in the 10000 units per year whilst also achieving MRL6-7\. This will allow supporting the production for prototypes and develop the learning for the next scaling up that will target high volume production (\>1M Foils per year).The consortium will be led by Reaction Engines, as the developer and manufacturer of the Foils and will include the Manufacturing technology Centre (MTC) as partner.The programme will start on 1st September 2022 and complete by end of December 2023\.
