报告摘要：The heavy reliance of lithium-ion batteries (LIBs) has caused rising concerns on the sustainability of lithium and transition metal (TM) and the ethic issue around mining practice. Developing alternative energy storage technologies beyond lithium has become a prominent slice of global energy research portfolio. The alternative technologies play a vital role in shaping the future landscape of energy storage, from electrified mobility to the efficient utilization of renewable energies and further to large-scale stationary energy storage. Potassium-based batteries (PIBs) are a promising alternative given its chemical and economic benefits, making a strong competitor to LIBs and sodium ion batteries (SIBs) for different applications. The presentation will discuss the advantages of potassium-based batteries, particularly the K-O2 battery, as well as the challenges associated with their development. Furthermore, our recent progress in potassium superionic conductors will be discussed, which will be crucial in solving challenges in potassium batteries. In addition, as the Deputy Editor of ACS Applied Energy Materials, I will be happy to answer any questions about the journal and encourage researchers to consider submitting their cutting-edge work.

报告人简介：Yiying Wu received his B.S. in chemical physics from the University of Science and Technology of China in 1998, and his Ph.D. in chemistry from the University of California at Berkeley in 2003 with Prof. Peidong Yang. He then did his postdoctoral research with Prof. Galen D. Stucky at the University of California, Santa Barbara, and joined the chemistry faculty at The Ohio State University in the summer of 2005. He was promoted to associate professor with tenure in 2011 and to full professor in 2014. From 2017 to 2022, he was appointed as the Leet Endowed Chair. He has been serving as an associate editor for ACS Applied Materials and Interfaces from 2013 – 2024, and the Deputy Editor of ACS Applied Energy Materials since 2024. His group focuses on materials chemistry and interface synthesis for energy conversion and storage. He is the inventor of the one-electron K-O2 battery and pioneered solar batteries that integrate solar harvesting with energy storage. He received Cottrell Scholar Award in 2008, NSF CAREER Award in 2010, CAPA Biomatik Distinguished Faculty Award in 2014, Franklin County Commissioner’s Award in 2014, Midwest Energy News “40 under 40” in 2015, Nano Research Top Paper Award in 2019, and ACS Akron Award in 2019. His invention of K-air battery received DOE Clean Energy Prize in 2014.
