Abstract: Provided is a method for producing a negative electrode material for a lithium secondary battery. The method for producing a negative electrode material for a lithium secondary battery may comprise the steps of: preparing a base structure including lithium-titanium-oxide (Li4Ti5O12, LTO); improving the electrical conductivity and lithium ion conductivity of the base structure by primarily heat treating the base structure; and eliminating oxygen vacancies present in the primarily heat-treated base structure by secondarily heat treating the primarily heat-treated base structure.

Abstract: An anode active material comprising a transition metal oxide is provided. A method for preparing the anode active material may comprise the steps of preparing a first transition metal oxide source and a second transition metal oxide source; providing the first transition metal oxide source and the second transition metal oxide source for a secondary alcohol to prepare a base source; providing a hydrolysis catalyst for the base source and inducing a sol-gel reaction to prepare a transition metal oxide precursor; and subjecting the transition metal oxide precursor to heat treatment in a nitrogen environment to prepare an anode active material containing a transition metal oxide.
