Abstract
Disclosed is to a method of manufacturing an anode active material, including mixing a first solution having a metal oxide precursor dissolved therein, a second solution having a polymer as a carbon fiber precursor dissolved therein, and an ionic liquid solution for nitrogen doping and formation of a porous structure, thus preparing an electrospinning solution, electrospinning the electrospinning solution, thus preparing a metal oxide-nitrogen-porous carbon nanofiber composite, and thermally treating the composite, and to an anode and a lithium battery using the anode active material.
