Dr. Yong Yang is now a distinguished professor in Chemistry in the State Key Lab for Physical Chemistry of Solid Surface at Xiamen University since 1997. He now also serves as Editor for J Power Sources, The 1st Vice President of International Battery Materials Association (IBA) and International Meeting of Lithium Battery (IMLB). His main research interests are new electrode/electrolyte materials for Li/Na-ion batteries, in-situ spectroscopic techniques, and interfacial reaction mechanism study in electrochemical energy storage and conversion system. He published 400+ papers in referred journals (H=87, Google Scholar) and as leading editor of two books entitled “Solid State Electrochemistry” (Chinese, 2017) & “NMR/MRI of Electrochemical Energy Storage Materials & Devices” (English, 2021), He obtained several awards such as Technology award from Battery Division, ECS (2020), Distinguished Contribution Award from Chinese Electrochemical Society (2017) and Technology Award from International Battery Materials Association (2014). His main recent research interests are Solid-State batteries, interfacial electrochemical reaction mechanism and in-situ spectroscopic techniques such as NMR and XAS, and Li-ion Battery Ageing and Degradation Analysis for Power and Storage Applications.
