Battery imaging
Imaging techniques are decisive in battery material analysis and battery failure diagnosis. Our group focuses on imaging techniques of multi-length scales to understand the major problems, including interface stability and dendrite growth, in all-solid-state lithium/sodium/magnesium metal batteries. At …
Ion transport mechanism in solid-state ionic conductors
Solid-state ion batteries have attracted considerable attention due to their safety, high energy density, and fast charging capability characteristics. Fast ionic conductor is the key component of the solid-state battery. However, there are …
Battery interface studies
Chemical and Electrochemical processes at solid-liquid and/or solid-solid interfaces are essential to cycle life of lithium-ion/lithium-metal batteries. In conventional lithium-ion batteries with liquid electrolyte, electrolyte decomposition results in the formation of a solid-electrolyte interphase (SEI), and this …
