While working in the secondary battery equipment field, I experienced firsthand how crucial ensuring stability is in actual industrial sites.

Lee's journey highlights a successful transition from industry to academia, driven by a desire to deepen his understanding of critical issues in the secondary battery sector. "While working in the secondary battery equipment field, I experienced firsthand how crucial ensuring stability is in actual industrial sites," Lee stated. "Afterward, I re-organized the fundamentals of mechanical engineering in the department and wanted to expand the problem awareness I felt in practice into research, which led me to pursue graduate studies."

He attributes his success to the structured curriculum and the repetitive learning opportunities offered by Korea Cyber University's online platform. "At first, I had many concerns about whether I could be competitive through online classes alone, but thanks to the systematic curriculum and the environment that allows for repeated learning, I was able to increase my understanding of the major," Lee explained. The flexibility of online learning allowed him to balance his studies with work, reinforcing his foundational knowledge and enabling him to articulate his research interests more logically during the application process.

Professor Baek Chang-hyun of the Mechanical Control Engineering department at Korea Cyber University emphasized the program's balanced approach to theory and practice. "The Mechanical Control Engineering department operates its curriculum to allow for a balanced learning of theory and practice, and supports students in developing the ability to define and solve problems on their own," Baek said. "This acceptance case is a meaningful achievement that shows it is possible to advance to world-class research-oriented universities even in an online educational environment."

Lee's specific research interest lies in the safety and thermal management of secondary batteries, crucial areas given their widespread use in electric vehicles and electronics. He plans to investigate the vulnerability of electrolytes to heat and fire and explore conditions for safer use. His prior experience in equipment verification and quality control in the battery manufacturing industry is expected to be a significant asset in his graduate research, enabling him to meticulously compare experimental results and generate reliable data.
