Laboratory for Electrochemical Materials & Devices @ DGIST

3S (Superiority, Safety, and Sustainability) for Future Energy Solution

Thanks for reaching out! This is research website of the laboratory for electrochemical materials & devices (LEMD) led by Prof. Hongkyung Lee (이홍경) in the Department of Energy Science & Engineering at Daegu Gyeongbuk Institute of Science and Technology (DGIST). We performs "advanced battery research" at the intersection of chemistry, interface, materials science, and engineering. Our research is aim to to build a better battery to solve complex energy-related environmental challenges. To achieve our goals, we are not only exploring a new battery chemistry and most suitable materials to realize the advanced battery systems, but also going to reveal the fundamentals on the interface phenomena within various electrochemical cells. We are further looking for possible pathway to open up the practical applicability of the proposed concepts and materials.

Our research is highly interdisciplinary, drawing from influences in chemical engineering, mechanical engineering, materials science, physics and chemistry. The research lab is now under construction to be capable to use a variety of tools for advanced functional materials coating, including atomic layer deposition (ALD), a wide range of characterization tools, including X-ray photoelectron spectroscopy, high-resolution electron microscopy, and optical and x-ray spectroscopy. Our work is funded by a wide range of federal and industry sponsors, and we will collaborate with research groups in Universities and National Laboratories throughout the world.
