Patent abstract
In a lithium transition metal oxide having a layered structure, one is provided, which is particularly excellent as a positive electrode active material of a battery on board of an electric vehicle or a hybrid vehicle in particular. A lithium transition metal oxide having a layered structure is proposed, wherein the ratio of the crystallite diameter determined by Measurement Method 1 according to the Rietveld method with respect to the mean powder particle diameter (D50) determined by the laser diffraction/scattering-type particle size distribution measurement method is 0.05 to 0.20.
