酸化物系全固体型リチウムイオン二次電池研究へのクリスタルサイエンスのアプローチ

抄録

  Energy conversion and storage, producing alternative fuels, and environmental purification are of growing importance to realize sustainable societies. All-solid-state lithium ion rechargeable batteries (All-solid-state LIBs) using oxide-based solid electrolytes have the potential to drastically improve the high energy, high power and high safety of current (liquid-type electrolytes) LIBs. Many researchers are focusing on bulk-type all-solid-state LIBs. However, these LIBs are well-known to have key performance problems. The difficulties lie in decreasing defects in materials and constructing well-connected interfaces between different materials because these are general causes of scattering of conductive carries. I believe that crystal science approaches will definitely help with solving the bottleneck problems of all-solid-state LIBs.
