17th GREEN Open Seminar

Schedules 2011.08.31 Finished


Dr. Kazuo Yamamoto, Researcher, Japan Fine Ceramics Center, will give us lecture with the following title; “Electron holographic observation of all-solid-state Li-ion battery".

Abstract

"Electron holographic observation of all-solid-state Li-ion battery"

All-solid-state lithium-ion batteries (LIBs) with nonflammable solid electrolytes offer the possibility of avoiding some safety issues associated with conventional LIBs that contain combustible liquid electrolytes. However, they have a lower power density, and this is mostly attributed to the large resistance to Li-ion transfer across the electrode/solid-electrolyte interface. To date, knowledge of how the local electric potential varies during Li-ion transfer has been unattainable. Recently we succeeded in operating the battery in a TEM and observing the potential by in-situ electron holography. In this lecture, we will introduce the principle of electron holography and show the latest results.
