Nanocrystal oxide/glass composite mesoporous powder or thin film, process for producing the same, and utilizing the powder or thin film, various devices, secondary battery and lithium storing device

摘要

The present invention aims to realize (1) manufacture of a mesoporous composite powder or thin film composed of nanocrystalline metal oxide—glass having a three-dimensional structure with a large specific surface area, (2) construction of a porous structure framework with nanocrystalline metal oxide crystal and a slight amount of glass phase (SiO2 or P2O5, B2O3), (3) control of crystal growth of metal oxide with a slight amount of glass phase (SiO2 or P2O5, B2O3), (4) simplification of the manufacturing process, and (5) use thereof in manufacture of a lithium intercalation electric device, photocatalytic device, solar battery and energy storage device. Provided are a nanocrystal oxide—glass mesoporous composite powder or thin film having a three-dimensional structure with regularly arranged mesopores, and a secondary battery comprising the same.
