PROBLEM TO BE SOLVED: To provide a lithium titanium composite oxide exhibiting high effective capacity, high rate characteristics, and excellent coating-film formability.SOLUTION: The lithium titanium composite oxide contains LiTiO, has a number-based existence ratio, of 5-15% or 40-65%, of particles having a particle size of 0.1 μm or less in SEM observation, a number-based existence ratio, of 15-30%, of particles having a particle size of 0.3-1.5 μm, and a specific surface area value of 5.8-10.1 m/g measured by BET method. The average particle size D50 in particle size distribution measured by laser diffraction measurement is preferably 0.6-1.5 μm. |
