项目摘要

Sodium-ion is emerging as a rival chemistry to the ubiquitous lithium-ion owing to its sustainability, lower cost and increased safety. Today, UK based Faradion and AMTE Power are manufacturing sodium-ion cells in the region of 140Wh/kg opening up 48V mild hybrid and 48V light mobility markets alongside 12V SLI (starting/lighting/ignition) lead acid replacement. This project's vision is to open up sodium-ion to the market of full-EV's by developing a high capacity anode material in excess of 500mAh/g which translates to a cell level energy density exceeding 200Wh/kg. The Centre for Process Innovation will screen processes and materials for techno-economics at TRL2\. Nuria Tapia-Ruiz at the University of Lancaster then identifies promising candidates in half cells at TRL3\. These are then progressed further in single layer pouch cells (TRL4) manufactured at Deregallera. Finally, the best material is tested in double-sided electrode multilayer pouch cells in a size and format guided by the Automotive end-users (TRL5). The National Physical Laboratory supports with their latest operando techniques to lift the fog of empirical analysis during material discovery process development and directly elucidate the electrochemical reaction pathways. In parallel, Deregallera responds to a techno-economic assessment the CPI conducted during round 3, to drive down the cost of their 240mAh/kg (140Wh/kg cell) hard carbon, opening opportunity for a UK based supply chain.

钠离子由于其可持续性、较低的成本和更高的安全性，正在成为无处不在的锂离子的竞争对手。如今，总部位于英国的Faradion和AMTE Power正在生产140 Wh/kg的钠离子电池，开辟了48 V轻度混合动力和48 V轻型移动市场，以及12 V SLI（启动/照明/点火）铅酸替代品。该项目的愿景是通过开发超过500 mAh/g的高容量阳极材料，将钠离子推向全电动汽车市场，这意味着电池级能量密度超过200 Wh/kg。工艺创新中心将在TRL 2\中筛选工艺和材料的技术经济性。兰开斯特大学的Nuria Tapia-Ruiz随后在TRL 3\的半细胞中鉴定出有希望的候选物。然后在Deregallera制造的单层软包电池（TRL 4）中进一步进行。最后，在汽车最终用户（TRL 5）指导的尺寸和格式的双面电极多层袋式电池中测试最佳材料。国家物理实验室支持他们最新的操作技术，以解除材料发现过程开发期间经验分析的迷雾，并直接阐明电化学反应途径。与此同时，Deregallera回应了CPI在第三轮期间进行的技术经济评估，以降低其240 mAh/kg（140 Wh/kg电池）硬碳的成本，为英国供应链提供机会。
