Abstract
An object of the present invention is to provide a lithium secondary battery which has improved capacity, durability, and rate 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 (003) plane is oriented in a direction intersecting the direction of the plate surface of the particle or film.
