Claim Text:
1. A positive electrode for a lithium secondary battery, comprising: a positive electrode current collector; and a positive electrode active material layer over the positive electrode current collector, wherein the positive electrode active material layer includes: wherein a b-axis of the rectangular parallelepiped or substantially rectangular parallelepiped particle of the lithium-containing composite oxide having the olivine structure is oriented vertically to a surface of the positive electrode current collector, wherein a number of rectangular parallelepiped or substantially rectangular parallelepiped particle having b-axis thereof oriented vertically to the surface of the positive electrode current collector is larger than a number of rectangular parallelepiped or substantially rectangular parallelepiped particle oriented in other axes directions, and wherein a peak intensit ratio of a (020) diffraction to a (101) diffraction of the lithium-containing composite oxide having the olivine structure in a X-ray diffraction spectrum is greater than or equal to 4.5 and less than or equal to 5.5.
