에너지/전자재료 분석 연구실(Energy/Electronic Materials Analysis Lab)

Batteries are central to modern energy technologies, from electric vehicles to large-scale energy storage. Lithium-ion batteries offer high energy density and reliability, lithium metal batteries promise the ultimate capacity, and sodium-ion batteries provide a sustainable, cost-effective alternative. Our laboratory studies the fundamental reaction mechanisms and degradation processes in these systems, aiming to uncover the origins of performance limitations and guide the development of safer, more durable, and higher-performance batteries. Lithium-ion batteries are at the heart of electric vehicles and energy storage systems, and their further advancement critically depends on the development of high-performance cathode materials. Our laboratory focuses on understanding the fundamental reaction mechanisms and degradation behaviors of advanced cathode materials, including high-nickel NMC, Li/Mn-rich (LMR), and LiNiO₂ (LNO), which are among the most promising candidates for next-generation lithium-ion batteries. Through atomic- and nanoscale investigations, we aim to uncover the origins of performance limitations and provide fundamental insights that guide the design of more durable and higher-energy cathode materials. Lithium metal batteries represent the ultimate form of rechargeable batteries, offering the potential to dramatically surpass the energy density of conventional lithium-ion batteries by employing lithium metal as the anode. However, the formation of lithium dendrites and the accumulation of dead lithium remain critical challenges, severely degrading performance and raising serious safety concerns. Our research aims to uncover the fundamental origins of dendrite growth and dead lithium formation in lithium metal batteries. Based on these mechanistic insight
