abstract |
The present invention relates to a positive electrode active material, a positive electrode material, a positive electrode, and a nonaqueous electrolyte secondary battery. [Problem] In a non-aqueous electrolyte secondary battery, a means for suppressing a decrease in capacity during long-term use and improving power characteristics is provided. [Solution] A positive electrode active material for a non-aqueous electrolyte secondary battery, characterized in that the true density/tap density of the secondary particles of the lithium composite oxide containing nickel as a main component is in the range of 1.6 to 2.3, and In the secondary particles, the average porosity at the center side is larger than R/2 [μm] of the particle radius R of D50 of the secondary particles than R/2 [μm] of the particle radius R of D50 of the secondary particles Average porosity on the more surface side. |
