Abstract: Lithium metal anodes are expected to drive practical applications that require high energy‐density storage. However, direct use of metallic lithium causes safety concerns, low-rate capabilities, and poor cycling performance due to unstable solid electrolyte interphase (SEI) and undesired lithium dendrite growth. This talk will focus on the development of novel energy storage materials such as effective and robust solid-electrolyte interface (SEI) materials for high capacity li-metal batteries. New nanofabrication methods including plasma enhanced deposition of Li3N and radio frequency sputtered graphite‐SiO2 ultrathin bilayer on Li metal chips are discussed as effective solid-electrolyte interface (SEI) layers. These lead to a dendrite free uniform Li deposition to achieve a stable voltage profile and outstanding long hours plating/stripping compared to the bare Li. In addition, innovative energy conversion materials such as active light harvesting perovskite materials, hole transport materials, and electron transport materials for efficient solar energy utilization are presented. Nano- and micro-fabrication for batteries, solar cells, and biosensors will also be discussed.

Bio: Dr. Qiao is currently a professor at Mechanical and Aerospace Engineering Department and also an affiliate professor at Electrical Engineering and Computer Science Department at Syracuse University. He is founder for Fastsol Power, Inc, a start-up company to commercialize batteries and their intrinsic integration with photovoltaics for sustainable energy generation and electric vehicles. He is site director for NSF IUCRC Center for Solid State Electric Power Storage (CEPS). He has also been working on nano- and micro-fabrication for batteries, solar cells, and biosensors.
