Design and Engineering of Interfaces/Interphases for Stable Li Anodes
 
Date: 2018-06-12
Time: 11:00
Venue: ABII402会议室
Speaker: Prof. Donghai Wang(王东海教授)

报告摘要:Li metal and Li-alloy based anode materials are the most promising anodes for next-generation Li batteries. The poor interfacial stability (unstable solid-electrolyte interphase (SEI)) in the battery has been the primary issue hindering their practical application. In this talk, I will present a strategy to reinforce the SEI with desired properties including good tolerance to the Li-based material volume change and efficient surface passivation against electrolyte penetration. The strategy works via introducing multiple functional components bonded to the Li-based material surface into the SEI. The SEI reinforced shows much better stability than the SEI reinforced by electrolyte additive strategy, which is the current state-of-art and commercially used solution to SEI stability issue.

报告人简介:Donghai Wang is Professor at Department of Mechanical Engineering and Department of Chemical Engineering at The Pennsylvania State University. Before joining Penn State in 2009, he was a postdoc and subsequently became a staff scientist at Pacific Northwest National Laboratories where he developed functional materials for catalysis and energy storage techniques.  He received a B.S. and Ph.D. degree in Chemical Engineering from Tsinghua University and Tulane University in 1997 and 2006, respectively.
Dr. Donghai Wang’s research interests have been related to design and synthesis of materials for a variety of applications. His recent research is focused on material development for energy conversion and storage technologies such as batteries, supercapacitors, fuel cells and solar fuels. Professor Wang has authored and co-authored over 90 peer reviewed publications, more than 15 patents and patent applications, and 4 book chapters.
