ABSTRACT:
A positive active material for non-aqueous electrolyte secondary battery is provided comprising lithium manganese oxide having such a spinel structure that the half-width (2θ) of the reflection peak corresponding to 440 plane as determined by X-ray diffractometry using CuKα ray is not greater than 0.145°. The use of this positive active material makes it possible to obtain a secondary battery which exhibits a good cycle life performance at room temperature and high temperatures and a reduced capacity drop when stored at high temperatures.
