NOVELTY - The mesoporous metal oxide microsphere electrode comprises a mesoporous transition metal oxide microsphere composition having microspheres with an average diameter of 1-2 mu m and mesopores provided on a surface and interior of the microspheres. The mesopores have an average diameter of 10-15 nm, and the microspheres have a surface area of 50-500 m2/g. The microspheres are comprised of nanograins with average diameters of 5-10 nm. The mesopores are uniformly distributed throughout the surface and the interior of the microspheres. The mesoporous metal oxide microsphere is used as an anode.    USE - The mesoporous metal oxide microsphere electrode is useful for a lithium-ion battery (all claimed), which is useful in electric vehicles, portable electronic devices and medical devices and for grid storage application.    ADVANTAGE - The mesoporous metal oxide microsphere electrode improves energy density, capacity, performance and charge-discharge capability of the lithium-ion battery.    DETAILED DESCRIPTION - The mesoporous metal oxide microsphere electrode comprises a mesoporous transition metal oxide microsphere composition having microspheres with an average diameter of 1-2 mu m and mesopores provided on a surface and interior of the microspheres. The mesopores have an average diameter of 10-15 nm, and the microspheres have a surface area of 50-500 m2/g. The microspheres are comprised of nanograins with average diameters of 5-10 nm. The mesopores are uniformly distributed throughout the surface and the interior of the microspheres.
