The HIgh Silicon content anOdes for a solid state batteRY Project [The HISTORY Project]

加速采用零排放电动汽车(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。虽然传统的基于液体电解液的锂离子电池(LIB)是为电动汽车提供动力的主流技术，但与LIB相比，固态电池(SSB)技术有望迅速提供安全和性能改进。在这个项目中，总部设在英国的合作伙伴将为开发一种多层固态气囊电池做出贡献，其规格符合电动汽车组件开发商的需求。Ilika将设计和制造SSB电池；Nexeon将开发基于其低膨胀NSP-2材料的高硅含量电极，用于SSB电池的阳极；工艺创新中心将用硅粉配制油墨；圣安德鲁斯大学将研究界面和材料之间的相互作用；伦敦大学学院和帝国理工学院将在单层、多层和封装层面模拟SSB和硅阳极的膨胀和收缩；HSSMI将为减少环境影响和改善寿命结局提供建议。

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.
