| titleOfInvention | Positive electrode active material for non-aqueous electrolyte secondary battery and non-aqueous electrolyte secondary battery using the positive electrode active material |
| abstract | (57) [Problem] To provide a positive electrode active material for a non-aqueous electrolyte secondary battery excellent in discharge capacity under a high load, and a non-aqueous electrolyte secondary battery using the positive electrode active material. SOLUTION: The positive electrode active material substantially uses lithium cobaltate represented by a general formula LiCoO 2 , wherein the lithium cobaltate is composed of secondary particles in which a large number of primary particles of small crystals are aggregated, and The secondary particles have many minute gaps through which the electrolyte can penetrate, and the tap density is 2.1 g. / Cm 3 or more, and it is preferable that at least a part of the small crystals constituting the secondary particles are bonded by sintering, and the secondary particles are spherical or elliptical spherical. It is preferred that Further, the average particle diameter of the secondary particles is 4 μm or more and 30 μm or less, and the average particle diameter of the primary particles is 0.4 μm or more and 10 μm or more. The following is preferred. A non-aqueous electrolyte secondary battery using the above-described positive electrode active material as a constituent element is characterized. |
