MSE Special Seminar: Revolutionizing Battery Technology - Engineering Quantum Materials for Enhanced Safety and Performance in Solid Electrolytes
Abstract: In the face of escalating smartphone usage, with a 2024 consumer report citing that 97% of U.S. individuals own at least one, the challenge of battery overheating has become prevalent. My doctoral studies present a groundbreaking approach to this issue by engineering a quantum material as a solid electrolyte with superior ionic mobility at optimal operational temperatures. Utilizing wet chemistry, I synthesized quantum dots to create Cu chalcogenides with superionic conductivity, enhancing battery safety and performance. My postdoctoral work extended these findings, exploring reduced-dimensional quantum wells and transitioning from cadmium-based to copper chalcogenides, leveraging copper's recyclability. My current research also delves into high-pressure X-ray studies performed at synchrotrons, uncovering new material phases and enhancing electrolyte stability. In a parallel avenue, I investigated perovskite-based solar batteries, aiming for efficiency improvements through innovative synthesis and material assembly. In this talk, I will discuss how to effectively utilize atomically precise material engineering toward the discovery of energy materials meant for high-priority energy storage applications. My vision includes developing nonflammable, high-conductivity solid electrolytes from abundant elements, optimizing synthesis via machine learning and advancing understanding of ionic transport in solid electrolytes. Collaborations and advanced imaging techniques, like time-resolved electron energy loss spectroscopy, are integral to this endeavor, aiming to revolutionize electrolyte design for safer, high-performance batteries.
