| Abstract Scope |
Over the past decade, the use of mesoscale (particle- or interface-resolved) models of battery electrodes has grown tremendously. Much of our work at Sandia National Laboratories has focused not only on electrochemical performance at the particle scale, but how material deformation and stress generation couple with electrochemical processes to influence both electrochemical performance and degradation. This work has long purported to provide physical insights to improve the fidelity of macroscale models often used for cell design. So, what have we learned? In this talk, we look into the mesoscale mechanics of a variety of battery electrode materials, including NMC, FeS2, and Li metal. We explore what role mechanics has on electrochemical processes, and vice versa. We also take a step back and identify how macroscale models have been adapted to include these effects and can continue to be improved in the future. |
