    摘要： An object of the present invention is to realize more effective intercalation and deintercalation of lithium ions in a cathode active material. The preset invention provides a cathode active material plate-like particle for a lithium secondary battery, the particle having a layered rock salt structure, wherein lithium-intercalation/deintercalation-plane-oriented grains (primary crystal grains whose (003) plane is oriented so as to intersect a plate surface of the plate-like particle) are present in a dispersed state among numerous (003)-plane-oriented grains (primary crystal grains whose (003) plane is oriented in parallel with the plate surface of the plate-like particle).

    摘要： An object of the present invention is to provide a lithium secondary battery which has improved capacity, durability, and the other characteristic as compared with conventional lithium secondary batteries. A plate-like particle or a film for a lithium secondary battery cathode active material has a layered rock salt structure. The lithium ion gateway plane is oriented in parallel with a plate surface, which is a surface orthogonal to a thickness direction of the particle and thus exposed at the plate surface, a plurality of layers are stacked together in the thickness direction, and while the layers have the same crystal axis in the thickness direction, as for the plate surface direction perpendicular to the thickness direction, the layers have different crystal axes.
