Abstract
A negative electrode active material for a secondary battery and a lithium secondary battery including the same. The negative electrode active material for a secondary battery, includes lithium titanium-based composite particles comprising: a lithium titanium oxide represented by LiTiO, wherein x, y and z satisfy 0.1≤x≤4, 1≤y≤5 and 2≤z≤12, Zr doped into the lithium titanium oxide; and an aluminum and sulfur containing compound coated on a surface of the lithium titanium oxide. The aluminum and sulfur containing compound is present in an amount of 0.4 mM to 0.9 mM based on 1M lithium titanium oxide.
