Full Summary: Modeling nano-architected electrodes with elastic instabilities: The role of buckling on electrochemical performance


The development of next generation lithium-metal alloy electrodes which make us of Si, Sn, Al, Au, and Ge can revolutionize the energy storage industry. In practice, however, the high volume expansion of the host material, and accompanying generation of stresses, can have a significant deleterious effect on the electrochemical performance of these electrodes. One promising path for circumventing these mechanical degradation issues is through the use elastic instabilities. However, at present there is no numerical tool to enable the rational design of nano-architected electrodes which buckle. 

In this work, we develop numerical tools for modeling the electrochemical performance of nano-architected electrodes undergoing buckling. Our approach makes use of two types of simulations, i) a detailed fully-coupled finite-element model which accurately resolves the transient behavior of these complex systems, and ii) a simplified reduced order model which integrates enough physics to provide a reasonably accurate estimation of the electrochemical performance at a fraction of the computational cost.



Claudio V. Di Leo is an assistant professor of Aerospace Engineering at the Georgia Institute of Technology. Dr. Di Leo received his Ph.D. (2015), M.S. (2013), and B.S. (2010) in Mechanical Engineering from the Massachusetts Institute of Technology, where his research focused on modeling hydrogen diffusion in metals and the chemo-mechanics of Li-ion batteries. In November 2016, Dr. Di Leo joined Georgia Tech as an assistant professor of Aerospace engineering. His research interests lie in the coupling between chemistry and mechanics of materials, particular how we harness this coupling for improved chemical and mechanical performance.
