Abstract
An object of the present invention is to provide a cathode active material which contains small-particle sized and low-crystalline lithium transition metal silicate and which undergoes charge-discharge reaction at room temperature. The cathode active material for a non-aqueous electrolyte secondary battery is characterized by containing a lithium transition metal silicate and exhibits diffraction peaks having half widths of 0.175 to 0.6°, the peaks observed through powder X-ray diffractometry within a 2θ range of 5 to 50°.
