Symposium Driving Discovery: Integration of Multi-Modal Imaging and Data Analysis
Presentation Title 3D and 4D Characterization of Failure Mechanisms in Commercial Li-Ion Batteries

On-Site Speaker (Planned) Jeff Gelb
Abstract Scope The modern world has witnessed an increased reliance on energy storage technology in recent years, to address sustainability concerns on portable and stationary device scales. Lithium-ion batteries (LIBs) are of particular interest, and recent advancements in portable electronics, hybrid- and fully-electric vehicles, and grid-level energy storage have benefitted from the advancements made in LIB technologies. In order to predict LIB functional performance and ultimate failure modes, our recent work has used X-ray microscopy to identify possible failure modes and relate them to electrochemical performance characteristics. Here, an initial study surveying a commercial 18650 cylindrical battery using a variety of correlative imaging modalities will be presented. This will be followed by a presentation of our recent work, where the 4D evolution of the cathode layer within a packaged battery was observed to crack with increased fatigue cycling. A discussion of ongoing work in modeling of these structures will also be presented.
