E-mobility, especially electric cars, has been scaling up rapidly because of technological advances in lithium-ion batteries (LIBs). However, LIBs degrade significantly with service life cycles. With the current increase in the adoption of electric vehicles (EVs), a large volume of retired LIB packs, which can no longer provide satisfactory performance to power an EV, will soon appear. Various end-of-life (EOL) options are under development, such as recycling and recovery. Recently, stakeholders have become more confident that giving the retired batteries a second life by reusing them in less-demanding applications, such as stationary energy storage, may create new value pools in the energy and transportation sectors. In this perspective, we evaluate the feasibility of second-life battery applications, from economic and technological perspectives, based on the latest industrial reports and technical publications.

Thanks are due to Dr. Thomas Tancogne-Dejean & Prof. Dirk Mohr for the nice work!

Two sessions were held virtually. One was with colleagues in the Eastern US and Europe, and the other was with colleagues in the Western US and Asia. There are more than 70 registered participants from all our sponsors (Apple, AVL, Hyundai, Murata, Tesla, Toyota North America, VW/Porsche/Audi) and other interested companies (Aperam, Cummins, Honda, GM, Mercedes-Benz North America, Magna, Metalsa, Renault, Revian, Stellantis, etc )

There will be three exciting talks from MIT and Imperial College London. Come and join us on Sunday at 9 am EST with this Zoom link!

My talk is entitled "Safety-Focused Modeling of Li-ion Batteries: Physics-Based Models, Data-Driven Approaches, & Their Intelligent Combination." The recorded video of the talk is here.

Our review article entitled "Guiding the design of heterogeneous electrode microstructures for Li-ion batteries: microscopic imaging, predictive modeling, and machine learning" is just accepted by Advanced Energy Materials today. This a joint paper of UConn, Bazant Group, NREL, UCL, and the University of Pisa. Please check out our paper when it is online available!

Today, I gave a talk at the Texas A&M Ocean Engineering Seminar, entitled "Electro-Chemo-Mechanics of Li-ion Batteries: from Physics-Based to Data-Driven." I was joined by around 70 faculties and students. I also enjoyed the fundamental discussions after the talk!

Our paper entitled "Large-Deformation Plasticity and Fracture Behavior of Pure Lithium under Various Stress States" is accepted by Acta Materialia, the leading journal in metallic materials engineering and sciences. This study is a joint work of our team, Tasan group @ MIT DMSE, and Lian Group @ Aalto. Special thanks are due to our visiting student Tobias Sedlatschek! This study has been presented at several conferences, including the 2020 SES Technical Meeting, in which we won the "Most Watched Video Presentation" Award.

Our Perspective paper entitled "The Application of Data-Driven Methods and Physics-Based Learning for Improving Battery Safety" is accepted by Joule, the leading journal in the energy field. This is a joint paper of our team, NREL, Tsinghua, and Imperial College London. Thank you Donal for leading this paper!
