There is currently a growing demand for low-cost, high-performance electrochemical energy storage solutions to consumer electronics, vehicle electrification and stationary power management. The successful development and deployment of such solutions necessitate a fundamental understanding of electrochemical materials’ chemical and physical characteristics including their mechanical properties, as well as the intricate coupling between the electro-chemo-mechanical processes in these materials. In this talk, I will present our recent work on multiscale characterization of deformation and fracture in silicon electrodes for lithium battery applications. Experimental results from full-field optical measurements and high-resolution transmission electron microscopy (HRTEM) will be presented and their technical implications will be discussed.
