WUHAN, China (April 1, 2021) - Wuhan Optoelectronics Forum No. 174 was successfully held in Auditorium D302 at Wuhan National Laboratory for Optoelectronics (WNLO) in the afternoon of April 1. Researcher Peng Zhangquan from Dalian Institute of Chemical Physics, Chinese Academy of Sciences delivered an inspiring speech entitled In-situ Spectroscopy Study on Reaction Principle of Lithium-Air Battery. Prof. Yan Shen from WNLO chaired the forum and awarded Researcher Peng Zhangquan the forum medal.
Researcher Peng’s lecture was based on the origin of the human earth. He began by introducing the history of oxygen, the universe, and optical technology. He clarified the working principles and modification methods of hydrogen-oxygen fuel cells and metal-air batteries. He explained the types of Li-O2batteries, the scientific problems and technical challenges of Non-aqueous Li-O2batteries, the detection of reaction intermediates, and the confirmation of elementary reactions. He also introduced the important role of in-situ spectroscopy in the study of reaction mechanism, intermediate detection, and solvation mechanism of Li-O2batteries, especially the clarification of reaction sites, charge transport and intermediate activity. Finally, he made an outlook on the future research hotspots and difficulties of lithium-air batteries.
Peng is currently a researcher at the Dalian Institute of Chemical Physics and is also a recipient of the National Science Fund for Distinguished Young Scholars. He graduated from Wuhan University with a bachelor's degree in July 1997, and received a master's degree and a doctorate degree from the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences in July 2000 and December 2003, respectively. From April 2004 to April 2012, Peng successively engaged in post-doctoral research at the University of Düsseldorf, University of Aarhus, and University of St. Andrew. From April 2012 to September 2020, he was a researcher at Changchun Institute of Applied Chemistry. He joined Dalian Institute of Chemical Physics in September 2020. Peng's main research directions include field spectroscopy/mass spectroscopy electrochemistry, computational electrochemistry, and lithium ion/lithium-air batteries. So far, he has published more than 50 SCI papers in Science, Nat. Mater., Nat. Chem., Nat. Commun., Angew. Chem. Int. Ed., J. Am. Chem. Soc., Nano Lett. and other journals. At the same time, he also won the honorary titles of British Newtonian Scholar and German Humboldt Scholar.
