MESOPORÖSES PULVER ODER MESOPORÖSER DÜNNER FILM AUS VERBUNDWERKSTOFF AUS NANOKRISTALLINEM OXID UND GLAS, HERSTELLUNGSVERFAHREN DAFÜR UND VERWENDUNG DES PULVERS ODER DÜNNEN FILMS, VERSCHIEDENE VORRICHTUNGEN, SEKUNDÄRBATTERIE UND LITHIUMSPEICHERVORRICHUNG

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 (SiO 2 or P 2 O 5 , B 2 O 3 ), (3) control of crystal growth of metal oxide with a slight amount of glass phase (SiO 2 or P 2 O 5 , B 2 O 3 ), (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.
