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.
