The lithium-ion battery (LIB) features structural and chemical complexities across a broad range of length scales. An in-depth understanding of the battery function, degradation, and failure mechanisms requires a thorough investigation from the structural, chemical, mechanical, and dynamic perspectives. In this talk, I present a macro-to-nano zoom through the hierarchy of a standard battery cell using a suite of state-of-the-art X-ray characterization techniques. Damage, deformation, and heterogeneity at different length scales are visualized and are associated to different degradation phenomena and mechanisms. Our results highlight the importance of the cathode material’s mechanical properties, which could significantly impact both immediate and long-term cell behaviors. Going beyond battery research, I will also briefly discuss the application of X-ray characterization tools for applications in the semiconductor industry and in electronic device packaging.

Join us to celebrate successes and wins as we highlight how California IEEE organizations are broadening their professional and educational outreach. Kathleen A. Kramer, Cal Tech PhD, currently professor of Electrical Engineering at the University of San Diego, will be our featured speaker at 6PM to highlight success stories, particularly with San Diego outreach activities such as Expand Your Horizons, FIRST LEGO League and the FIRST Technical Challenge. Kathleen will be followed a panel of Bay Area and Silicon Valley IEEE leaders, and will discuss with them their challenges and achievements in creating diverse groups and sustaining energy, given the many obstacles over the past 3 years. Jerry Chang Larry Moody Jacqueline Radding Peter Fischer Pizza and beverages will be served from 5:15-6PM prior to the event. Parking on campus is $2 per hour and $10 per day, see below for parking instructions and map.
