题目：Aqueous Lithium-Air Batteries with Protected Lithium Electrode
报告人：Nobuyuki Imanishi Mie University
Lithium-air battery system consists of a lithium metal anode, an electrolyte, and a carbon-air cathode. Two types of lithium-air batteries have been developed based on the electrolyte type; non-aqueous and aqueous solutions. The paper will focus on the aqueous system in which the following reaction occurs. 4 Li + 6H2O + O2 = 4(LiOH-H2O) The energy density of the aqueous system is approximately 2000 Wh kg-1 including oxygen. This value can achieve the target of energy density announced by NEDO, Japan. The aqueous systems potentially have three kinds of electrolytes. The requirements and issues for each electrolyte will be discussed.
NOBUYUKI IMANISHI is a professor at department of chemistry, Mie University in Japan. He began his research career on industrial electrochemistry as undergraduate student in 1982 at Kyoto University and received PhD in 1993 under the direction of Professor Zen-ichiro Takehara of Kyoto University.
He joined Mie University in 1990, where he focuses on functional materials and electrochemistry, especially energy conversion and storage materials, for instance, electrode materials for lithium batteries and fuel cells, and solid-state electrolytes for those batteries. His recent research interests include two main topics: lithium-air batteries and solid polymer lithium ion batteries. He has participated in several research projects. Among them he was a group leader of aqueous lithium-oxygen battery research in the JST national project ALCA-Specially Promoted Research for Innovative Next Generation Batteries. He has published more than 300 refereed papers and many book chapters, and also served as a book co-editor on lithium-air batteries.
He chaired the 56th Battery Symposium in Japan in 2015, which accepted 560 papers and 2500 delegates. His research has been recognized by awards including The Electrochemical Society of Japan, ECS Japan Sano Award (1995), The Committee of Battery Technology, Award for Young Battery Researchers (2002), The Electrochemical Society of Japan, Research Paper Award(2016), The Electrochemical Society, Battery Division Reserach Award (2016) .
