Ohio University’s Chemistry and Biochemistry Colloquium Series presents Dr. Liu Tianbiao on “Developing New Battery Chemistries for Sustainable Energy Storage”, Monday, Sep. 23, at 1:00 p.m. in Walter Hall 235.

Tianbiao is an Assistant Professor of chemistry and materials science at Utah State University

The host is Dr. Jixin Chen.

Abstract: In response to rapid increasing energy storage demands of consuming electronics, electrical vehicles, electrical grids, and renewable energy integration, there is an urgent call for advanced rechargeable batteries with superior energy storage performance and more affordable material costs compared to existing battery technologies. The presentation will cover our research efforts in developing new battery chemistries towards sustainable and economical electrochemical energy storage. Through rational molecular engineering, we have designed and applied redox active molecules including viologen (anolyte), quinone (anolyte), TEMPO (catholyte), ferrocene (catholyte), and ferrocyanide (catholyte) for developing aqueous organic redox flow batteries (AORFBs). The chemistry and battery performance of redox active molecules will be discussed in detail. In addition, the chemistry of quinone based redox active MOFs and their applications in developing Li metal rechargeable batteries will also be presented. Particularly, this presentation emphasizes that in-depth mechanistic understandings of redox active materials at the molecular level play crucial roles in developing new generation of rechargeable batteries.
