Hi, I’m Jinwoo Lee, a Lithium-ion Battery Cell Design & Development Engineer with over 5 years of hands-on R&D and mass production experience. I specialize in developing advanced separators to mitigate lithium plating and designing high-power, high-capacity lithium-ion cells for the North American EV market. In my current role at LG Energy Solution, I lead chemistry design, cell validation, and mass-production optimization for upcoming EV models. Previously at ETRI, I focused on advanced materials R&D, creating novel separators to improve lithium plating behavior and enhance battery safety, and I performed extensive electrochemical testing and material characterization to push cell performance. I hold a Master and a Bachelor of Science in Fiber System Engineering from Dankook University, with a specialization in lithium-ion battery separator materials. I’m passionate about turning laboratory insights into robust, scalable energy storage solutions.…Hi, I’m Jinwoo Lee, a Lithium-ion Battery Cell Design & Development Engineer with over 5 years of hands-on R&D and mass production experience.
