Abstract: There is a growing interest in low-cost and scalable manufacturing and recycling methods for lithium-ion batteries (LIBs). In this talk, I will discuss on our recent progress in innovating materials and processing technologies for more sustainable LIBs. I will first discuss our recent work on the next generation direct recycling methods, aiming to produce new electrode materials capable of matching the performance of native materials. By leveraging advanced characterizations, we study the microstructure and compositional evolution of battery materials during cycling, which are compared with the recycled materials. We demonstrate successful recycling of various battery materials to high performance active materials. Scaling up challenges will also be discussed.
