Rechargeable batteries, such as the lithium-ion battery, are indispensable to continuously support sustainable modern society, but further development of a battery system with much higher energy density and longer durability is still required. To improve rechargeable batteries, it is essential to understand the structural evolution of the bulk and interfaces between anode, cathode, and electrolyte materials during charge-discharge processes. However, a real battery cell has so many chemical components and complex structures, making it difficult to diagnose respective materials and their interfaces in an electrochemical process. We need to prepare a simple model battery composed of high-purity materials such as single crystals, thin films, and solid-state crystal electrolytes.
This symposium will focus on investigations of the relationship between atomic structure and electrochemical property by using simple but high-quality battery materials. In addition to structure and property analyses, this symposium will cover growth methodology of high purity single crystals and thin films. The battery system is not only cation (lithium, sodium) but also anion (fluorine or sulfur) or the other multivalent-ion materials.
