A CLASS OF POROUS METAL OXIDE BASED ELECTROCHEMICAL ENERGY STORAGE MATERIALS, PREPARATION METHOD THEREFOR AND USE THEREOF

WIPO Patent Application WO/2020/253843

A1

Disclosed are a porous metal oxide based electrochemical energy storage material, a preparation method therefor and the use thereof. The porous metal oxide based electrochemical energy storage material at least comprises a host metal oxide having a multistage porous structure, and preferably also comprises a heterogeneous metal oxide locally deposited in the multistage porous structure of the host metal oxide structure and on the surface thereof, wherein the host metal oxide is of a single crystal, quasicrystal, or twin crystal structure with orderly arranged atomic lattices, is rich in oxygen atom vacancy defects in the crystal thereof, and has a general structure formula of MxOy-z, where M is selected from one of or a combination of two or more of the metal elements of niobium, molybdenum, titanium, vanadium, manganese, iron, cobalt, nickel, copper and zinc, where 1≤x≤2, 1≤y≤5, and 0.1≤z≤0.9, preferably Nb2O5-z.
