"Nanotechnology for the Next Generation of Batteries, Supercapacitors, and Solar Cells"

Ms. Shan Hu

Department of Mechanical Engineering
University of Minnesota


Nanostructured materials with unusual properties not found in bulk materials can provide exceptional performances not achievable by traditional devices. The first part of this seminar will talk about how the unique properties of carbon nanotubes (CNTs) are explored to develop essential components for a solar-powered active noise control window system, including an invisible speaker, flexible supercapacitors, and transparent solar cells. Poor scalability and high production cost, the two major drawbacks of many nanomaterial-based devices, were overcome in this research by making the CNTs solution-processable. The impact of the developed energy generation/storage components on other real world applications will also be discussed.

The second part of the seminar will discuss the opportunities that exist for nanotechnology and control technologies to enhance the performance of renewable energy systems at the device level and the system level. Examples include (i) the use of nanostructured electrode materials for new Lithium-ion storage mechanism to achieve high-capacity Lithium-ion batteries, and (ii) the design of control systems for the energy management of hybrid energy systems (e.g. integrated solar-supercapacitor-battery systems, hybrid electric vehicles, etc.).


Ms. Shan Hu is a Ph.D. candidate in the Department of Mechanical Engineering at the University of Minnesota Twin Cities. She received her M.S. degree from the University of Minnesota Duluth in 2009 and her B.E. degree from the Harbin Institute of Technology, Harbin, China in 2007. She was awarded the Doctoral Dissertation Fellowship from the University of Minnesota’s Graduate School to complete her Ph.D. research, which uses carbon nanomaterials to develop the next generation devices for energy and biomedical applications. Her work on carbon nanotube-based paper supercapacitors was featured in Applied Physics Letters’ 50th Anniversary Collection and chosen as one of the “Most Read APL Articles in 2012”.
