The broader impact/commercial potential of this SBIR Phase II project is to significantly improve the economics of lithium-ion battery (LIB) recycling, while minimizing its environmental impact. Direct recycling uses less energy and generates less pollutive waste and fewer emissions than alternative recycling approaches, while simultaneously producing more valuable products. The proposed project will advance the development of a recycling technology that will lower LIB cost, reduce the reliance of LIB production on the mining of expensive virgin metals, create a local supply of LIB materials, and facilitate the adoption of clean energy products (e.g., electric vehicles, grid storage). This SBIR Phase II project proposes to develop a cost-effective and scalable direct recycling process at a pilot-scale level. The proposed project will study LIB deactivation, component separation, purification, and regeneration processes that can be economically reproduced on a large scale. For example, a battery deactivation process that is quicker, safer, and cost-effective can be used in other waste management processes as well to discharge batteries. This project also will enable a better understanding of the key parameters of electrode extraction and purification processes able to preserve electrode chemistry and morphology. By focusing on the characterization of structure, morphology and electrochemical performance of the recycled materials, this project will lead to a more profound understanding of the effect of relithiation and heat treatment conditions on the quality of recycled cathode materials. Together, these studies will advance the knowledge and understanding of not only the process, chemistry, and mechanics behind the direct recycling process but also process optimization for a production-scale LIB recycling operation.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该SBIR II期项目的更广泛的影响/商业潜力是显着改善锂离子电池（LIB）回收的经济学，同时最大程度地降低其环境影响。直接回收利用的能量较少，比替代回收方法更少的投票浪费和更少的排放量，同时生产更多有价值的产品。拟议的项目将推动开发一种回收技术，该技术将降低LIB成本，降低LIB生产对开采昂贵的原始金属的依赖，创建本地LIB材料的供应，并促进采用清洁能源产品（例如电动汽车，电网存储）。这个SBIR II期项目提议在试点规模的水平上开发一个具有成本效益且可扩展的直接回收过程。拟议的项目将研究可以大规模经济复制的LIB停用，成分分离，纯化和再生过程。例如，可以在其他废物管理过程中使用更快，更安全且具有成本效益的电池停用过程以及放电电池。该项目还将更好地了解电极提取和能够保留电极化学和形态的纯化过程的关键参数。通过关注结构，形态和回收材料的电化学性能的表征，该项目将使人们对重新考虑和热处理条件对再生阴极材料质量的影响有更深入的了解。这些研究共同提高了直接回收过程背后的过程，化学和机制的知识和理解，而且还可以对生产规模的LIB回收操作进行优化。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响审查审查标准来通过评估来通过评估来支持的。
