All-solid-state lithium-ion batteries: Challenges and opportunities
Angelique Jarry, Senior Technology Manager – Battery
Moses Lake Industries, Portland, Oregon, ajarry@mlindustries.com
Abstract.—All-solid-state batteries (SSBs) are widely seen as the next-generation energy storage system due to their inherent safety and other benefits. However, further development of SSBs is still impeded by the current lack of understanding/engineering at the interfaces formed upon cycling. Recent progress in the development of characterization surface techniques using synchrotron radiation or lab sources has enabled major scientific advancements toward this understanding. The challenges and approaches of transitioning from the standard liquid electrolyte-based lithium-ion batteries to all-solid-state batteries with multi-electron transfer will be presented. Examples will include strategies to mitigate capacity fading originating from the structural distortion-electronic band structure changes occurring from the free surface to the buried interfaces. I will provide an overview of how, by using complementary state-of-the-art spectroscopy and microscopy techniques, we build a stronger foundation in the knowledge needed to achieve kinetic control of interfacial processes, to provide rational guidance to battery developers working toward stable and effective electrode/surface layer/electrolyte formulations.
Bio: Dr. Angelique Jarry is a senior technology manager at Moses Lake Industries where she manages the Battery R&D to develop high purity chemicals and processes to introduce novel products and technology to the growing lithium-ion market. She has over 15+ years of experience in materials R&D for electrochemical systems. Her expertise encompasses materials synthesis and characterization tools to shed light on the bulk and interfacial processes that govern the performance of electrochemical systems. Dr. Jarry received her PhD in 2012 from the University of Nantes. As a Postdoctoral Fellow, she then performed diagnostic studies of surface films in lithium-ion battery systems in the Kostecki group at Lawrence Berkeley National Laboratory (2012-2015) and explored conduction mechanisms at solid/liquid and solid/gas interfaces in electrochemical systems using in situ AP-XPS at the Advanced Light Source (2015-2017). As an Assistant Research Scientist in the Rubloff’s group at UMD (2017-2020), she developed 3D solid-state battery patterned structures, solid-state electrolyte for battery system, Li metal protection layer and spectro-electrochemical diagnostic methods.
