Accelerating the adoption of emission-free electric vehicles (EV) is widely seen as a key contributor to reaching Net Zero and reducing the release of greenhouse gases in the environment. Whilst conventional liquid electrolyte-based lithium ion batteries (LIB) are the incumbent technology for powering EV, solid state battery (SSB) technology is expected to rapidly provide safety and performance improvement compared to LIB. In this project, UK-based partners will contribute to the development of a multi-layer, solid state pouch cell with specifications aligned with the need of electric vehicle pack developers. Ilika will design and fabricate the SSB cell; Nexeon will develop a high silicon content electrode based on its low expansion NSP-2 material to be used in the anode of the SSB cell; Centre for Process Innovation will formulate inks with the silicon powders; University of St Andrews will characterise interface and materials interactions; University College London and Imperial College London will model the expansion and contraction of SSB with silicon anode at single-layer, multi-layer and pack level; HSSMI will provide recommendations for reduced environmental impact and improved end-of-life outcomes.

加速采用无排放的电动汽车（EV）被广泛视为实现净零排放和减少环境中温室气体排放的关键因素。虽然传统的液体电解质基锂离子电池（LIB）是电动汽车的主流技术，但与LIB相比，固态电池（SSB）技术有望迅速提高安全性和性能。在这个项目中，总部位于英国的合作伙伴将为多层固态袋状电池的开发做出贡献，其规格与电动汽车电池组开发商的需求保持一致。伊利卡将设计和制造SSB电池；Nexeon将以其低膨胀NSP-2材料为基础，开发用于SSB电池阳极的高硅含量电极；工艺创新中心将用硅粉配制油墨；圣安德鲁斯大学将描述界面和材料相互作用；伦敦大学学院和帝国理工学院将在单层、多层和包层水平上模拟硅阳极SSB的膨胀和收缩；HSSMI将提供减少环境影响和改善生命末期结果的建议。
