ABSTRACT:
There is provided a metal oxide having a continuous nano-fiber network structure as a negative active material for a secondary battery. A method for fabricating such negative active material for a secondary battery comprises spinning a mixed solution of a metal oxide precursor and a polymer onto a collector to form composite fibers mixed with the metal oxide precursor and the polymer, thermally compressing or thermally pressurizing the composite fibers, and thermally treating the thermally compressed or thermally pressurized composite fibers to remove the polymer from the composite fiber.
