Research Abstract

The in situ observation techniques of the solid-liquid surface during electrochemical reactions were developed. To understand the interface structure, the in situ neutron reflectivity cells with electrochemical reactions were designed. And interface structures changes of the actual electrode were observed. The changes of reflectivity profile were determined and those changes were consistent with the changes of the amount of lithium ions in the electrodes.
