Farshid Ramezanipour, PhD

Dr. Ramezanipour joined the Department of Chemistry in August 2015. A Ph.D. graduate of McMaster University (2011), Dr. Ramezanipour was a Postdoctoral Fellow at the University of Calgary (2011-2013) and a NSERC Postdoctoral Fellow at the University of California, Berkeley (2013-2015).


His group designs and synthesizes solid state oxides for application in energy conversion devices. Material synthesis is a major component of our research and we invest significant effort in establishing correlations between structure and properties of complex oxide materials. They also explore the electronic and ionic conductivity of these materials for application in fuel cell devices.


They work on solid lithium-ion conductors for solid electrolytes in lithium-ion batteries, which can enhance the safety and performance of these batteries.


They utilize a large number of characterization methods, including diffraction techniques, electronic and ionic conductivity measurements, scanning and transmission electron microscopy, x-ray photoelectron spectroscopy and electrochemical impedance spectroscopy to understand the properties of new materials that we synthesize, and explore their potential applications in different areas including fuel cells and batteries.”

Hui Wang, PhD

Dr. Hui Wang, Ph.D. is an Assistant Professor of Mechanical Engineering at the University of Louisville. Dr. Wang earned her Ph.D. degree from Michigan Technological University in 2013. After then, she had been a Postdoc research associate at Oak Ridge National Laboratory before she joined University of Louisville in 2016. Dr. Wang’s research focuses on Novel Materials for Renewable Energy Storage and Conversion Systems, such as All-solid-state Batteries, Li-ion Batteries, Na-ion Batteries, as well as Solar Cells. Dr. Wang also has been awarded “Dean’s Award for Outstanding Research Scholarship”, “Doctoral Finishing Fellowships” as well as “China’s Government Award for Outstanding Graduates Abroad”.


Dr. Wang’ research on all-solid-state batteries focus on three aspects: (a) solid electrolyte materials design and synthesis. We can synthesize various kinds of solid electrolyte materials, such as Li3PS4, Li2S-P2S5, LLZO, LLTO, Li3OCl and so on. We keep searching for novel and fast ion conductors and explore their properties and applications in all-solid-state batteries. (b) solid electrolyte manufacturing. We are interested on solid electrolyte manufacturing to reduce the cost for large-scale materials processing. (c) interface engineering between solid electrolyte/electrodes. We investigate the interface stability between solid electrolyte and both Li anode and cathode materials such as S. In summary, our research goal is to develop all-solid-state batteries with high performance (capacities, rate performance, cycle life) for the next-generation energy storage systems.
