| titleOfInvention |
Active material of positive electrode for non-aqueous electrode secondary battery and method for preparing the same and non-aqueous electrode secondary battery using the same |
| abstract |
The present invention relates to a positive electrode active material for a non-aqueous electrolyte secondary battery using lithium cobalt acid represented by the formula LiCoO 2 , which is in the range of 0.4 to 10 μm in the Ferre diameter of the projection drawing by SEM observation and has an average particle diameter. It consists of the mixture of the primary particle of the small crystal which is 5 micrometers or less, and the secondary particle in the range of 4-30 micrometers in which many small crystals gathered, and the molar ratio of Co to Li is 0.97 or more and 1.03 or less, It is preferable that at least a part of the small crystals constituting the secondary particles are bonded to each other by sintering, and the secondary particles are spherical or elliptical in shape. In addition, 90% or more of the particles having a Feret diameter of 9 µm or more are secondary particles, and the volume ratio of particles having a volume ratio of 6 µm or more is 70% or more of the mixture as a whole. A positive electrode active material for an aqueous electrolyte secondary battery, a manufacturing method thereof, and a non-aqueous electrolyte secondary battery using the positive electrode active material. |
