Research question
Which local atomic environments allow oxygen to supply additional charge capacity in lithium-rich cathodes?
Key result
Lithium-rich coordination, including Li–O–Li arrangements, creates oxygen electronic states that can be oxidized more readily. This connected oxygen redox to local structure and provided a basis for cathode design.
Research contribution
Dong-Hwa Seo performed DFT calculations and co-developed the theory with Jinhyuk Lee. They jointly designed project details and analyzed the results under Gerbrand Ceder’s supervision. This work predates the current KAIST group.
