Professor Young-Beom Kim's research lab specializes in advanced materials for energy conversion and storage, with a strong focus on solid-state energy devices. The lab develops novel thin-film deposition and sintering techniques—such as atomic layer deposition (ALD), flash-light sintering, and intense pulsed light processing—to engineer high-performance, nanostructured functional oxides. Key research directions include optimizing catalytic and protective layers for solid oxide fuel cells, all-solid-state batteries, and water electrolyzers, with an emphasis on enhancing interfacial stability, ionic conductivity, and electrochemical activity at low temperatures and minimal noble metal usage. The lab also investigates perovskite-based materials, particularly for bifunctional electrocatalysis and interface engineering in next-generation energy systems.

Because noble metal catalysts (e.g. Pt) are one of the main contributors to low-temperature (<500 °C) fuel cell costs, significant efforts have been made to lower the noble metal loading in constructing fuel cell electrodes. In this work, ultra-thin (∼10 nm) platinum (Pt) cathode/catalyst layers were patterned by atomic layer deposition (ALD) and tested as catalytic electrodes (cathode) for low-temperature solid oxide fuel cells. We found that 180 cycles or approximately 10 nm of ALD Pt, with a
Perovskites are a challenging new class of highly efficient bifunctional catalysts that hold huge significance in advanced batteries and water electrolysis. The surface chemistry and surface electronic structures of the La0.6Sr0.4CoO3−δ (LSC) perovskite is greatly modified upon postsynthesis sintering. Herein, a new strategy has been demonstrated by intense pulsed light technology to accomplish the sintering process in milliseconds, and is comparatively explored with conventionally sintered LSC.
