Born in 1976, Lee graduated from Chungcheong University with a degree in mechanical design. She later studied in the Department of Convergence Mechanical Engineering at Jungwon University and completed a bachelor’s degree in business administration at Kyung Hee University, followed by a master’s program at its graduate school of business.
In 2010, she founded Yujin Technology in Cheongju, North Chungcheong Province. She has designed and operated precision presses, molds and battery process equipment, while also accumulating on-the-job experience as CEO.
Yujin Technology specializes in batteries, producing parts and equipment for the notching process — the first step in battery assembly — as well as lead tabs used as materials in assembly. Its notching molds are supplied exclusively to some affiliates of South Korea’s three major battery makers, the company said, and it holds a 60% share of the domestic market.
As association chair, Lee has focused on training technical workers and strengthening the industrial base for the battery and electric vehicle sectors. The association trains field-oriented specialists through education in battery performance evaluation, diagnostics, repair and fire safety. It has produced more than 1,200 battery professionals and built a cooperation network with about 50 organizations. It has also worked beyond training to develop a battery terminology dictionary and standards related to used batteries and fires, the article said.
Lee, a female engineer and CEO with broad experience across the battery production floor, said securing “field-ready” talent is urgent for the industry’s continued growth. While battery technology and equipment are advancing quickly, she said, skilled workers who can understand and operate them remain in short supply.
“Industrial competitiveness ultimately depends not on technology, but on people who understand the field,” Lee said. “More important than equipment are technicians who can handle it properly.”
Reflecting that view, the association is focusing on developing practical technicians who can understand batteries accurately, handle them safely and make data-based judgments, the article said.
“Going forward, securing talent with core capabilities such as battery safety and fire response will determine market competitiveness,” Lee said. “The association will work to build an ecosystem where technicians are properly evaluated and can play a central role in the industry.”
