Yang Kook Sun is a professor of Energy Engineering at Hanyang University, Korea. He received his PhD in Chemical Engineering from Seoul National University in 1992. After that, he joined Samsung Advanced Institute of Technology, where he was the team leader of the lithium polymer battery and his contribution was a cornerstone for the commercialization of the lithium polymer battery of Samsung SDI. He received the “Grand Prize Award” from the Korea Patent Association due to his contribution to lithium ion battery commercialization in 1999. After joining Hanyang University in 2000, he became an active member of The Korean Academy of Science and Technology in 2007, The National Academy of Engineering of Korea in 2016, and became a Distinguished Professor at Hanyang University in 2008.
Professor Sun is also very active in the scientific community, giving a large number of invited talks, chairing many sessions, and organizing conferences on energy storage. He contributes a lot to our community by serving as a senior editor for ACS Energy Letters and before then he served as an editor for the journal of Power Sources. For his contributions in his field, he received a myriad number of awards for his accomplishments including Research Awards from the Energy Technology Division and the Battery Division of The Electrochemical Society (ECS) in 2007 and 2011, R&D 100 Award from R&D Magazine in 2012, National Green Technology award from Korea Industrial Technology Association in 2012, Lithium-ion Battery award of Ministry of Trade, Industry, and Energy from Korea Battery Industry Association in 2014, Innovative Knowledge Award from Ministry of Science, ICT and Future Planning in 2015, and Engineering Award from Gyeongam Foundation in 2016. In addition, he was selected as a Highly Cited Researcher (HCR) for ranking among the top 1% of researchers in his specific field by Clarivate Analytics 2016, 2017, 2018 and 2019. He received Technology Awards from the Battery Division of ECS in 2017 and became ECS Fellow in 2019.
Professor Sun’s major research interests are design, synthesis and structural analysis of new innovative energy storage and conversion of materials, and their applications in electrochemical devices of lithium-ion, lithium-sulfur, lithium-air, and sodium-ion batteries. One of his pioneering research works in lithium-ion battery field is the establishment of core-shell and concentration-gradient type composite cathode materials based on lithium-nickel-cobalt-manganese oxides. These innovative cathode materials have been licensed in 2008, 2010, and 2014 by three Korean companies and have recently undergone production for use in E-bike batteries by LG Chemical Ltd and in ‘2018 Niro EV’ electric vehicle batteries by Kia Motors Corporation. The concentration-gradient cathode material has received further attention from numerous companies and is expected to be employed for electronic vehicles. We anticipate that this novel approach should lead to the design and development of a wide range of other safe and stable high-capacity intercalation compounds. The concept of concentration-gradient has already been applied to sodium-ion cathode materials resulting in high-capacity and prolonged cycle life compared to conventiaonl sodium-ion cathode materials. Professor Sun has also contributed to the lithium-air battery community by setting the standard test-mode for operation through using cut-off capacity instead of cut-off voltage and employing tetraethylene glycol dimethyl ether (TEGDME) as most commonly used electrolyte in the field. Furthermore, he is fabricating high electrochemical performance pouch-type cells in lithium-sulfur and lithium-air batteries to investigate their practical cell performance and problems in commercial batteries which are shadowed in coin-type cells. Currently, he has expanded his research to lithium-metal-ion batteries for higher energy density batteries.
Today, his research has cumulated to more than 600 publications and 491 registered and applied patents in the field of batteries and electrochemistry. He is still very active in his field of research and continues to collaborate with multiple researchers from around the world to make contributions to the field of batteries and electrochemistry.
