PURPOSE:To provide a positive pole active material for a nonaqueous electrolyte secondary battery excellent in charge/discharge efficiency with high capacity by smoothly promoting intercalate/deintercalate reaction of lithium. CONSTITUTION:In a spherical and almost spherical or elliptical secondary particle 2, a plate-shaped monocrystal grain 1, having a stratified structure of regularly laminating a thin piece, is collected, and in almost or all the plate-shaped crystal grains for constituting a surface part of this secondary particle 2, a stratified structural surface of inercalating/deintercalating lithium is exposed toward the outside of this secondary particle 2. |
