Transportation accounts for 23% of energy-related carbon dioxide emissions and electrification is a pathway toward ameliorating these growing challenges. All solid state batteries could potentially address the safety and driving range requirements necessary for widespread adoption of electric vehicles. However, the power densities of all solid state batteries are limited because of ineffective ion transport at solid|solid interfaces. New insight into the governing physics that occur at intrinsic and extrinsic interfaces are critical for developing engineering strategies for the next generation of energy dense batteries. However, buried solid|solid interfac- es are notoriously difficult to observe with traditional bench-top and lab-scale experiments. In this talk I dis- cuss opportunities for tracking phenomena and mechanisms in all solid state batteries in-situ using advanced synchrotron techniques. Synchrotron techniques that combine reciprocal and real space techniques are capa- ble of tracking multi-scale structural phenomena from the nano- to meso-scale. This talk will discuss the role microstructure plays on transport and interfacial properties that govern adhesion. Quantification of salient descriptors of structure in solid state batteries is critical for understanding the mechanochemical nature of all solid state batteries.

Speaker Bio

Dr. Hatzell earned her Ph.D. in Material Science and Engineering at Drexel University, her M.S. in Mechanical Engineering from Pennsylvania State University, and her B.S./B.A. in Engineering/Economics from Swarth- more College. Hatzell’s research group works on multifunctional coatings and understanding phenomena at solid|liquid and solid|solid interfaces. The Inks and Interfaces group works on an array of different applica- tions related to solid state batteries, electrochemical fuel production, printing, water desalination, and sep- arations application. She is interested in understanding far-from equilibrium material systems and utilizes a suite of x-ray and neutron techniques to understand these systems. Hatzell was an ITRI-Rosenfeld Postdoctoral Fellow at Berkeley Lab and an NSF Graduate Research Fellow. She received the Arthur Nowick Award from Materials Research and the Siver Graduate Student Award in the Materials Research Society. Since joining Vanderbilt she has won the ORAU Powe Junior Faculty Award (2017), NSF CAREER Award (2019), ECS Toyota Young Investigator Award (2019), finalist for the BASF/Volkswagen Science in Electrochemistry Award (2019), and the Ralph “Buck” Robinson award from MRS (2019). Hatzell was also named a SCIALOG Fellow in energy storage by the Research Corporation for Scientific Advancement in energy storage (2017-2019).
