Abstract
The present invention provides a novel titanium-based composite oxide being usable as an electrode material for a lithium secondary battery and having a high capacity and an excellent cycle stability, a method for producing the same and a lithium secondary battery using the titanium-based composite oxide. Disclosed is a compound obtained by compositing titanium oxide with elements other than titanium, specifically a titanium-based composite oxide wherein the relevant chemical formula is TiMO, M is the element Nb or the element P, or a combination of these two elements in an optional ratio therebetween, x is such that 0<x<0.17, y is such that 1.8≦y≦2.1, x is the sum of Nb and P when M is a combination of the element Nb and the element P, and the present invention provides a lithium secondary battery using as an electrode the titanium-based composite oxide.
