报告人简介：

Nian Liu is an Assistant Professor at School of Chemical and Biomolecular Engineering at Georgia Tech. He received B.S. in 2009 from Fudan University, and Ph.D. in 2014 from Stanford University, where he worked with Prof. Yi Cui on the structure design for Si anodes for high-energy Li-ion batteries. In 2014-2016, he worked with Prof. Steven Chu at Stanford University as a postdoc, where he developed in situ optical microscopy to probe beam-sensitive battery reactions. Dr. Liu’s lab at Georgia Tech is broadly interested in the combination of nanomaterials, electrochemistry, and light microscopy for studying the global energy challenges. Specifically, the Liu’s lab is focusing on electric vehicle battery and stationary battery science and technologies. His publications have been cited over 15,000 times. He is the recipient of the Electrochemical Society (ECS) Daniel Cubicciotti Award (2014), American Chemical Society (ACS) Division of Inorganic Chemistry Young Investigator Award (2015), and Journal of Materials Chemistry A Emerging Investigator (2018).

报告的摘要：

Zinc-based batteries have found applications in devices ranging from hearing aid to grid-scale batteries, due to their superior safety, high energy and low cost compared to Li-ion counterpart. However, zinc-based batteries, particularly zinc anodes, historically suffer from poor rechargeability. Since the launch of my lab at Georgia Tech in January 2017, we have focused on developing tools to uncover the important information about battery materials, as well as engineering battery materials at the nanoscale to solve their intrinsic problems. In this talk, I will present our recent progress in designing nanostructured materials to mitigate the reversibility problem of zinc anodes. Next, I will show our in-operando visualization of liquid product formation and dynamics in Zn-Br stationary battery. Finally, I will show examples of applying the above two research approaches in other battery systems.
