On May 28, industry sources reported that Lee announced his decision in a letter to SK On employees, stating, "I wish to conclude my duties as CEO of SK On by the end of May," and added, "It has been a great honor to work alongside SK On members at the center of the secondary battery industry."
He explained, "I have been deeply contemplating the significant responsibilities of the CEO role since the end of last year, but I delayed my resignation to ensure the successful completion of key management issues, including the conclusion of our U.S. joint venture."
Appointed as president of SK On in December 2023, Lee previously held positions at Intel and served as a professor in the Department of Electrical and Electronic Engineering at KAIST. He also worked as the head of DRAM development at SK Hynix and as Chief Operating Officer.
Lee is recognized as an expert in global manufacturing, having received the Intel Technology Award three times, and is seen as the ideal leader to transform SK On into a top-tier global battery company focused on advanced technology.
He has played a crucial role in expanding SK On's presence in the North American market and establishing partnerships with automotive manufacturers.
In October of last year, SK On appointed Yoon Wook, former CEO of SK Siltron, as president, creating a dual leadership structure alongside Lee.
With Lee's resignation, SK On will transition from a dual leadership model to a sole leadership structure under Yoon Wook.
