In the pursuit of extending the driving range of electric vehicles (EVs), Chelsea Chen, a polymer physicist at the Department of Energy’s Oak Ridge National Laboratory, is spearheading research on ion transport in solid electrolytes. Chen aims to develop innovative battery chemistry designs that increase energy density and support longer battery life.
By studying solid polymer electrolytes, Chen is exploring potential solutions to enhance energy density in EV batteries. These electrolytes play a crucial role in improving the performance of solid-state batteries by optimizing their structure and properties at the interface between the cathode and anode. This research is part of her work at the FaCT center, a newly funded DOE Energy Frontier Research Center focused on solving scientific challenges related to energy storage and conversion materials.
Solid-state electrolytes offer an alternative to traditional liquid electrolytes, thereby addressing safety concerns associated with the reactions between liquid electrolytes and lithium metal anodes in lithium-ion batteries. Pairing solid-state electrolytes with a high-voltage cathode and a lithium metal anode can significantly increase energy density.
Chen’s passion for polymer research began during her undergraduate studies in China, where she worked closely with experts in the field. She later obtained her Ph.D. in macromolecular science and engineering from the University of Michigan and conducted postdoctoral research at the University of California, Berkeley, and Lawrence Berkeley National Laboratory.
Her career trajectory eventually led her to ORNL, where she has focused on advancing her understanding of polymers’ structures, properties, and behaviors. Chen appreciates the research-centric environment at a national laboratory, where she can prioritize fundamental research over commercial applications.
Beyond her work on EV batteries, Chen also advocates for the recycling and upcycling of polymers to reduce waste and improve sustainability. She hopes that her research will prompt stakeholders in the public and private sectors to consider end-of-life issues in polymer design.
Chen’s research at ORNL is supported by the DOE Office of Energy Efficiency and Renewable Energy and the DOE Office of Science, with her work leveraging the capabilities of the Spallation Neutron Source and the Center for Nanophase Materials Sciences.
