A joint research team led by Professor Sun Yang-guk, Department of Energy Engineering at Hanyang University, published a paper reviewing lithium oxygen batteries which is one of the next-generation secondary battery systems.
The joint research team includes Professor Sun Yang-guk of Hanyang University, Professor Kwak Won-jin of Ajou University, Professor Doron Aurbach of Israel's Biran University, Professor Peter Bruce of Oxford University in the U.K., and Professor Linda Nazar of Waterloo University in Canada. The paper was titled "Lithium–Oxygen Batteries and Related Systems: Potential, Status, and Future" and was selected as a cover paper for theJuly 22 online edition of "Chemical Review."
The research team introduced he structure, driving principles and related derived systems of lithium oxygen batteries based on their experiences and achievements. It also pointed out the key problems in relation to lithium oxygen batteries, latest research trends, and improvement directions considering practicality.
Lithium oxygen cells are next-generation secondary battery systems that utilize oxygen in the air as an energy source. It also has the potential to surpass the theoretical enery density limts of lithium ion batteries used in mobile phones and electric vehicles allowing active research. However, there are limitations like low energy efficiency caused by irreversible generation and decomposition of short-term battery life products caused by negative reactions by oxygen. Therefore, innovative research is required to solve these problems professionally.
Meanwhile, Professor Sun was recognized as one of the best 10 scientists in the field of lithium-ion batteries by Research Interfaces. The paper was selected as the best paper researcher of the school in 2020, and currently holds 599 SCI-level papers and 456 domestic and foreign patents. In particular, he was recognizedas the "world's most influential top 1% researcher" by Claribate Analytics.
