Aqueous Li-ion (Na) Battery: A Potential System for Stationary Power Source Application

Abstract:

Aqueous lithium-ion battery (LIB) and sodium-ion battery (SIB)  may solve the safety problem of LIB using organic electrolyte, as well as the undesirable cycling life of the commercialized aqueous secondary batteries (Pb acid, Ni-MH), but all reported aqueous LIB systems behaved poor cycling stability. In the present talk, the most recent research progresses of this new system in our lab will be introduced, including the mechanism responsible for capacity fading, self oxygen-elimination etc. Also the industrial application demonstration will be addressed. The aqueous LIB offers high safety, low cost, long cycling life and appropriate energy density, and shows potential application for stationary power sources.

Biography:

Dr. Yongyao Xia  is a professor in the Department of Chemistry and Institute of New Energy of Fudan University. He received a Bachelor of Science degree from the Chemistry Department of Zhejiang Normal University in 1987 and a Master of Science degree in Electrochemistry from the Chemistry Department of Jilin University in 1990. He received a PhD degree in Energy-Related-Material Science in Saga University, Japan in 1997. In 1998, he worked at the Department of Chemical Engineering, University of South Carolina as a Post-doctoral Research Associate. In 1999, he returned to Japan and worked as a Post-doctoral Research Associate in the Battery Section of Osaka National Research Institute. From 2001 to 2002, he worked as a Researcher at Hitachi Maxell Ltd. Starting from 2003, he becomes a full professor in Fudan University, China.

His research interests involve advanced materials and technologies for energy storage and conversion devices, e.g., lithium-ion batteries, electrochemical supercapacitors, lithium-air, lithium-sulfur batteries and fuel cells etc. He has published more than 250 papers in peer-reviewed scientific journals, contributed 3 book chapters, and hold 40 Japanese and Chinese patents on energy conversion and storage devices. The research works have been highly cited over 10000 times.

He received the award of New Century Excellent Talents in University, Ministry of Education (MOE) in 2005, and Outstanding Young Scientist Award of the Natural Science Foundation of China (NSFC) in 2009, Contribution Award in Electrochemistry of the Chinese Society of Electrochemistry (CSE) in 2015, and the First prize of Natural Science Award of MOE in 2015. Now, he serves as the president of the Chinese Society of  Electrochemistry (CSE) and Editor of Journal of Power Sources.
